Different dyes and chemicals are required to give the specific coloration effect of AF. AF are relatively difficult to dye due to their very crystalline structure and remarkable compactness. The different techniques, including supercritical carbon dioxide, microwave irradiation, liquid ammonia, ultraviolet treatment, co-polymerization, high temperature, carrier method, and ozone treatment, have already been utilized for the dyeing of AF. Among the processes, some of them show excellent dyeing performances in color fastness to wash, rubbing, and light. The AF also frequently used in harsh environments and cannot be cleaned in a timely manner; bacteria that develop on their surface might pose a health concern, making AF with antibacterial properties are extremely desirable. There have been a number of antibacterial treatments for AF to develop protection against gram-positive and gram-negative bacteria. The in-situ treatment of AF using silver nanoparticles (AgNPs) showed a high level of antibacterial activity. However, there are no reviews that discuss the coloration and antibacterial activity of AF. Therefore, this review summarized the coloration and antibacterial activity of AF using different dyes and nanoparticles.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136263732","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 effect of the MWCNTs addition on morphology and photocatalytic activity of the nanostructures was characterized by scanning electron microscopy (SEM), Raman spectroscopy, UV-Vis diffuse reflectance spectroscopy (DRS), photoluminescence (PL) spectroscopy, and methylene blue (MB) degradation tests. The results showed that MWCNTs were successfully incorporated into the TiO 2 nanotube structure, and significantly affected its photocatalytic activity. The best photocatalytic performance was achieved with the use of 0.025 g/L MWCNTs in the electrolyte composition.

Electrospun scaffolds with defined three-dimensional patterns at the mat surface can be efficiently fabricated using textured collectors that transfer the topography during the manufacturing process. However, the efficacy of surface pattern transfer from the collector to the mat, the correlation between the topography and the absorption capability and the effect of sterilisation on absorption have not yet been analysed. In this study, textured patterns were imprinted over polycaprolactone electrospun mats using textured collectors. The successful transferability of the patterns was quantified through height, hybrid and functional surface topography parameters. Additionally, ethylene oxide, hydrogen peroxide (H 2 O 2 ) and ultraviolet (UV) sterilisation methods were tested, of which only UV preserved the morphological and functional integrity of the mat. Finally, fibroblasts were used to analyse the cytotoxicity and cellular response of the dressings, verifying their biocompatible nature. This study demonstrates that absorption capacity can be modulated by the surface texture of the wound dressing. The S dq and S dr parameters were identified as key surface characteristics for enhancing absorption capacity and yielded an increase of up to 176.76% compared with the non-textured control, thus revealing the potential of surface functionalisation for increasing exudate absorption.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135805987","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}

However, existing slippery surfaces have the limitation of insufficient oil-locking capability for rough structures, which limits their practical application. To solve the aforementioned limitation, the authors developed a slippery surface with a good oil-locking capability. First, a wire-cutting machine tool was used to fabricate ternary coupled grooved structures on an aluminum (Al) substrate, which could increase the lubricant-storage capacity of the microstructures, and the substrate was named slippery porous surface with groove-textured aluminum (Slips-G-Al). Then, a surface durability test was performed involving lubricant shear, sandpaper wear and water impact. The chemical stability test involved acid, alkali, salt corrosion and weather resistance tests, which showed that Slips-G-Al had a good lubricant-storage capacity compared with the traditional Slips surface. In addition, the self-cleaning performance and the fog collection capability of Slips-G-Al were also studied. Finally, an electrochemical corrosion test of Slips-G-Al was carried out. The findings showed remarkable application prospects in the aerospace and shipbuilding fields.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135805986","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}

Through methods such as X-ray diffraction phase analysis, microscopic morphology analysis, roughness analysis, coating thickness analysis and hardness testing, it was found that the added graphite particles can react with silicon (Si) in the electrolyte to promote the formation of the silicon carbide (SiC) phase, thereby improving the surface morphology of the coatings, increasing the thickness of the coatings and improving the microhardness of the coatings. At the same time, dynamic potential polarization curve and scanning electrochemical test results show that the formation of the silicon carbide phase can increase self-corrosion potential and reduce self-corrosion current density. When the amount of graphite added is 1.0 g/l, the self-corrosion potential and self-corrosion current density are −0.129 V and 2.9 × 10 −8 A/cm 2 , respectively.

The MnO 2 -MnS 2 /P2AMB nanocomposite demonstrates remarkable optical properties, characterized by a bandgap of 1.81 eV. To promote the water splitting reaction by the synthesized MnO 2 -MnS 2 /P2AMB nanocomposite photoelectrode, sewage water is utilized as a sacrificial agent to effectively facilitate the generation of hydrogen gas through the evaluation of the current (J ph ). At −0.9 V, the J ph and J o values are determined to be −0.33 and −0.2 mA.cm -2 , correspondingly. Notably, the optimum J ph value of −0.26 mA.cm −2 is observed for incidence photons at 340 nm, indicating that light with higher frequency and energy leads to the generation of more electrons from the MnO 2 -MnS 2 /P2AMB nanocomposite and subsequent hydrogen production. Conversely, the lowest J ph value of −0.21 mA.cm −2 is obtained at 730 nm, suggesting the influence of infrared waves on the photoelectrode due to the small bandgap (1.86 eV) of the materials, as calculated in a previous analysis. This study represents an initial step towards the conversion of wastewater into hydrogen gas, which can serve as a sustainable fuel source for various industrial applications.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135199671","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}

A magnetic field enhances the plasma density and sputtering rate. The study examines the bonding force, surface morphology, tribological properties, and mechanical strength of DLC. Scanning electron microscopy, Raman spectroscopy, and X-ray photoelectron spectroscopy are used to characterize the cross-sectional morphology, structural features, and chemical bonding species of DLC films and NBR substrates. Nanoindentation results show that varying the power has no significant effect on hardness and Young’s modulus. Tribological tests are conducted under ambient conditions using a ball-and-disk tribometer, with a fixed load of 0.3 N. Results indicate that the power of DLC films influences their tribological properties. Specifically, DLC films prepared at 120 W exhibit superior tribological properties, maintaining a stable coefficient of friction (CoF) below 0.2 for the test duration.

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":null,"pages":null},"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}
