After storing for 5 days, WCA of PTFE stored under room temperature (25°C) recovered from 19 ± 2° to 54 ± 2°, while the WCA of PTFE stored under low temperature (−10°C) just increased to 42 ± 3°. Then, the mechanism contributing to the slower wettability recovery was investigated by analyzing surface chemical compositions via X-ray photoelectron spectroscopy (XPS) and observing surface morphologies using atomic force microscope (AFM). After 15 days storage, the contents of O and N decreased obviously, while F content increased. The F content of sample stored under low temperature was 20% less than that stored under room temperature. By contrast, surface micro-morphologies remained unchanged during storage, and the surface roughness Ra of each sample was around 7 nm. Finally, peel strength tests were conducted on APCP-treated PTFE surfaces stored under different temperatures, and the surfaces stored under low temperature maintained better adhesive property; after 15 days of storage, the adhesive strength could still reach 400 N/m, which was 376% higher than that of the untreated surface. The research results are expected to significantly facilitate practical applications of APCP modification and PTFE surfaces.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2023-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44174559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, pulsed plasma polymerisation was used to produce an antibacterial coating from the carvone oil of the spearmint plant. The coating films have adjustable chemical and physical properties based on the deposition parameter – that is, duty cycle (DC). The static water contact angle (WCA) values of pulsed wave (PW) plasma-polymerised carvone (ppCar) increase with the increase in DC. Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy showed that the molecular structure of carvone is less fragmented, retaining moieties associated with C–O and C=O when the DC is reduced. These C–O and C=O moieties likely reduced the measured static WCA. This surface chemical composition with predominantly C–O and C=O also showed a stronger bactericidal effect, based on the biofilm assay with bacteria (Escherichia coli and Staphylococcus aureus), compared with those coatings with C–C and C–H produced at a higher DC. As shown by the atomic force microscopy images, a lower DC resulted in smoother and more homogeneous coatings than those produced with a higher DC, while field emission scanning electron microscopy images show that when E. coli and S. aureus membranes were attached to PW ppCar, they ruptured and distorted with a pore created and that these distortions and ruptures increased as the DC was reduced.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135114544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study successfully prepared flexible and porous silicon dioxide (SiO2)–titanium dioxide nanofiber membranes (NFMs) by implementing electrospinning technology and calcination processes. The porous membranes demonstrate remarkable performance in water treatment, featuring a high specific surface area (49 m2/g) and porosity, enabling efficient adsorption and removal of organic pollutants in water. Remarkably, the NFMs-800 variant exhibits outstanding photocatalytic performance, achieving complete removal of adsorbed organic compounds under ultraviolet irradiation. The design and fabrication methods of this porous membrane are simple and scalable, providing a potential solution for practical water-treatment applications. Consequently, the silicon dioxide–titanium dioxide porous membrane holds significant prospects in the field of water treatment, offering a promising contribution to the attainment of efficient and sustainable water resource management.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2023-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46732905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that the volume ratio of the two droplets has a significant effect on the vibration modes. With the change of the volume ratio, the droplet exhibits different vibration modes, such as the pumping mode (PM), the rocking mode (RM), or the pumping-rocking mixed mode (PRM). In addition, the coalescence time of the two droplets varies with the volume ratio. When the volume ratio is close to 1, the two vibrated droplets are in synchronous pumping mode (SPM) and the coalescence time is the shortest. When the volume ratio is far away from 1, the two droplets may show the rocking mode (RM), the asynchronous pumping mode (APM), or the pumping-rocking mixed mode (PRM). At this point, the coalescence time gets increased, especially for the small volume ratios. Finally, the movement characteristics of the three-phase contact lines are discussed, and a theoretical model is proposed to analyze the coalescence process. This work provides a new method to remove droplets rapidly, which is essential to enhance the heat transfer performance of dropwise condensation.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46529075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, an effort was undertaken to see if Rheum Emodi (Rhubarb) extract might be used as a natural dye for wool dyeing for the replacement of synthetic dyes. The dyeing of wool fabric was carried out using microwave (MW) rays’ treatment. By combining several mordants, a stunning color pallet of shades of varying hue and tone was created. Comparative evaluation of the effects of various chemical mordants (aluminum salt, iron salt, tannic acid, and cream of tartar) and bio mordants (pomegranate extract, and pine nut hull extract) on the characteristics of dyed wool samples was carried out to choose the best mordant for each application. It was found that MW treated wool fabric using bio mordant shown higher color fastness value of 4/5 to 5 and color strength value of approximately 10 to 20 rather than using metallic mordant. Scanning electron microscopy (SEM) photographs and Fourier transform infrared spectroscopy (FT-IR) analyses revealed the difference between irradiated and un-irradiated wool fabric. The employment of MW rays and bio-mordants in the natural coloring of wool fabric is encouraged due to their biocompatibility and non-toxicity when combined with MW treatment of wool fabric, as well as their high color fastness and color strength performances. As a result, the naturally extracted dyes from rhubarb can be the replacement of synthetic dyes for the coloration of wool fabric in the textile industry due to their environmental issues.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48378512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although various extreme wettable materials are designed to achieve oil-water separation, there are still limitations such as expensive materials, fluorine-containing reagents, and poor robustness of oil-water separating materials. Here, we resolved the above problems by proposing a simple and low-cost sandblasting plating method with Ni, P, and 1-octadecanethiol modification to manufacture a robust superhydrophobic stainless steel mesh for separating oily water under harsh environments. The mesh can achieve the light and heavy oily water with outstanding separating efficiency and high purity. It can be also used to separate HCl solution, NaOH solution, and NaCl solution-oil, with the separating efficiency larger than 95%. Moreover, the mesh still was superhydrophobic and had outstanding oil-water separating efficiency after sandpaper abrasion, tape stripping, simulated seawater corrosion, and natural environment corrosion tests. Therefore, the robust superhydrophobic stainless steel mesh proposed in this work can very efficiently separate oily water in harsh environments.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2023-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42603286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chromate conversion coatings (CCC) have been widely used in industry over past decades, providing exceptional corrosion protection at relatively low cost for Al alloys. However, new environmental regulations prohibiting the use of Cr(VI) have raised a growing interest in development of the alternative technologies to CCC, but only titanium/zirconium (Ti/Zr) conversion coatings have been used in industrial applications thus far. However, there remain some disadvantages to these coatings, such as colorless appearance and poor corrosion resistance, which affects their wide application. Here, a colored Ti/Zr-based conversion coating, formed on AA6063 Al alloy using a solution containing C76H52O46(tannic acid, TA), H2ZrF6, H2TiF6, and NaVO3, was developed recently by ours, enabling rapid film-formation at room temperature and improved corrosion resistance. The influence of TA on the film-forming process of colored Ti/Zr-based conversion coatings was investigated using UV-Vis, XPS, and IR techniques, and the possible reaction process after adding TA, as well as the mechanism of rapid film formation and color rendering, were also explored. The results showed that, the large number of organic complexes formed by TA with metal ion during the aging process of conversion solution and film formation are the main reasons for the rapid film formation and color rendering of coating.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2023-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47687656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
