For the first time the combined effect of various textures after laser texturing and graphene synthesis on corrosion current and wettability before and after corrosion is investigated. Previous research works have shown that the surface wettability after laser texturing varies greatly over time, from superhydrophilic to highly hydrophobic. However, the present work shows that the combined effect of laser texturing and graphene synthesis allows stabilizing the wettability of textured samples over time, as well as significantly reducing the impact of corrosion on the contact angle. The droplet contact angle changes slightly over time after corrosion. The smallest change in the contact angle corresponds to the Cu/G surface for textures with craters. At that, the corrosion current of the textured Cu/G sample is reduced 12–14 times, compared with the textured copper. The use of textures with craters provides higher corrosion resistance than in the case of textures without craters. The performed XPS analysis reveals that that the textured wall with craters has a maximum peak C = C (C1s XPS spectra). A new mechanism is proposed to explain the different wettability inversion period for textured copper with graphene synthesis. The wettability of textured surfaces is simulated using molecular dynamics methods. The contact angle of the nanodrop depends on both the textures and the hydrophilicity of the polished surface. The obtained results will be useful for the development of combined methods and composite materials in materials science to control wettability, stabilize surface properties, as well as to counteract aggressive environmental effects.</div></div>","PeriodicalId":316,"journal":{"name":"FlatChem","volume":"48 ","pages":"Article 100770"},"PeriodicalIF":5.9,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142656237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this, the surface of tungsten disulfide (WS<sub>2</sub>) nanosheets is modified with temperature-responsive (poly(N-vinylcaprolactam)) and pH-sensitive (vinylacetic acid) polymers and then characterized using TGA, FE-SEM, XRD, and FT-IR techniques. Experimental variables including pH (5.56), temperature (25 °C), and contact time (11.02 min) are optimized using response surface methodology (RSM) and central composite design (CCD), yielding an adsorption efficacy of 99.45 %. The RSM-CCD model’s capability is analyzed using the correlation coefficient (R2) and several statistical error functions, including average relative error (ARE), root mean square error (RMSE), hybrid fractional error function (HYBRID), and Chi-square test (χ2). The in vitro drug release procedure is evaluated at different pH levels (5.6 and 7.4) and temperatures (37 and 50 °C). The results showed a maximum BCT release of 87.2 % within 6 h at 50 °C and pH 5.6, compared to 13.3 % at 37 °C and pH 7.4. Moreover, the BCT-loaded carrier demonstrates complete BCT release (100 %) following 10 min of NIR irradiation at pH 5.6.

Additionally, the kinetics of electron transfer was studied by EIS. Thereafter, proper optimization of various sensor parameters such as pH, scan rate and analytical performance were executed. Preliminary sensing studies carried out by cyclic voltammetry revealed an enhancement in peak current from 0.48µA to 1.05µA upon incorporation of rGO into the ZIF-L(Zn/Co) hybrid.
