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}

Similarly, SEM is employed to examine the morphological alterations of irradiated surfaces. The band gap and band tail of pristine and treated films were estimated using Tauc’s methodology. By raising hydrogen fluence from 6x1017 ions/cm2 to 12x1017 ions/cm2, the band gap is lowered from 5.06 eV to 4.86 eV. Furthermore, the band tail energy is improved from 0.53 eV for PVA to 0.55 eV for 6x1017 and to 0.63 eV for 9x1017 ions/cm2. In addition, the dispersion characteristics of were estimated using the Wemple Di-Domenico method. Moreover, the extinction coefficients and refractive index were calculated. The recorded relaxation time is reduced from 2.06x10−7 sec to 1.65x10−7 sec respectively, by enhancing ion fluence from 6x1017 to 12x1017 ions/cm2.

Maintaining the wetting stability of flexible superamphiphobic surfaces under stretching is challenging. Here, flexible surfaces with stable superamphiphobicity under stretching were fabricated by covering flexible polydimethylsiloxane substrates with superamphiphobic powders. Superamphiphobic powders composed of micro- and nanoparticles were prepared by a chemical substitution reaction and modification treatment. The fabricated flexible surfaces possessed contact angles for water, kerosene and peanut oil of 155, 152 and 153°, respectively, exhibiting superhydrophobicity and superoleophobicity. The self-cleaning properties of the fabricated flexible surface were studied by removing contaminants from the surfaces using water and oil droplets. Also, the wettability and morphology of the fabricated flexible surface under stretching were investigated. It was found that the fabricated flexible surface maintained stable superhydrophobicity and superoleophobicity when the stretching strain reached 60% due to the fact that it still kept micro–nano double-scale structures after being stretched. The fabricated flexible surface coated with superamphiphobic powders with wetting stability is expected to be used in the field of liquid repellency.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":"189 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135659037","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, developing a simple and universal method to fabricate wettability patterns on a variety of metals remains a great challenge. In this work, we developed three specific preparation approaches to fabricate wettability patterns on copper substrate using chemical processing combined with mask technology. Surface wettability can be suitably controlled by changing the solution concentration and immersing time. The surface has good stability and low pollution under external action. Three preparation methods have differences in preparation process, wettability and mask function. On the basis of these approaches, various complex wettability patterns could be prepared on different metal substrates using designed masks. Furthermore, various wettability-patterned surfaces were successfully fabricated for liquid manipulating applications, such as controlling fluid shape and water transport. These methods proposed is expected to have promising application potential in patternable printing, water collection and heat-dissipation devices.","PeriodicalId":22032,"journal":{"name":"Surface Innovations","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2023-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43401370","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}
