However, the combination of superhydrophobicity and supercapacitance in a single textile coating remains largely unexplored, representing a critical gap in current research. This study addresses this gap by developing a multifunctional nanocoating applied to polyester fabric using reduced graphene oxide (RGO) and a fluoropolymer (FP) via a spray mist coating technique. GO was synthesized by the Hummers and Hoffman method and reduced with environmentally friendly glucose. Structural and morphological modifications were confirmed through XRD, RAMAN, FTIR, XPS, and SEM-FEG analyses. The resulting nanocoated fabrics exhibited exceptional water repellency with contact angles exceeding 150°, enhanced washing, and abrasion resistance. A Box-Behnken design optimized key process parameters (RGO/FP ratio, curing temperature, and time) to achieve peak performance at a contact angle of 160° with a 1:5 ratio (RGO/FP), a curing temperature of 125°C, and a curing time of 2 minutes. Furthermore, the functionalized polyester fabric demonstrated a remarkable specific capacitance of 305.88 F/g, surpassing results from comparable studies and making it suitable for wearable supercapacitor applications. Durability tests revealed stable superhydrophobicity and structural integrity after five wash cycles, equivalent to 25 home washes. SEM-FEG analysis highlighted nanocoating-induced roughness, enhancing the lotus effect, while electrochemical evaluations indicated notable improvements in conductivity and energy storage. This environmentally friendly spray mist coating technique offers a scalable and sustainable approach for creating multifunctional textiles, paving the way for advanced applications in smart fabrics and flexible electronics.</div></div>","PeriodicalId":278,"journal":{"name":"Colloids and Surfaces A: Physicochemical and Engineering Aspects","volume":"716 ","pages":"Article 136696"},"PeriodicalIF":4.9,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143746357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the in-situ wettability of reservoir rocks at high temperatures is essential to prevent water phase trapping and optimize enhanced oil recovery methods. This study employs a high-temperature, high-pressure contact angle measurement system to assess water contact angles on various rock surfaces, within a temperature range of 20°C to 200°C, under an 8 MPa nitrogen atmosphere. The mechanism of temperature-dependent wettability changes was conducted using molecular simulation, atomic force microscopy, scanning electron microscopy, and energy-dispersive X-ray spectroscopy. Findings reveal that the contact angle on quartz surfaces reduces with temperature, exhibiting distinct segmented behavior. The rate of change in contact angle was approximately −0.07°/°C from 20°C to 100°C and −0.17°/°C from 100°C to 200°C. Under subcritical conditions, an increase in hydrogen bonds between water molecules and the silica surface, along with a reduction in hydrogen bonds between water molecules, markedly influences the wettability on quartz surfaces. Water contact angles on crude oil-adsorbed rock samples progressively declined with increasing temperature, from 108.3° to 52.3°, transitioning the surface from oleophilic to hydrophilic. The adhesion work of water on these oil-adsorbed rock surfaces remained nearly constant up to 100°C; beyond this, under subcritical conditions, the adhesion work surged, with a change rate of 49.14 % at 200°C. Microscopic analysis of rock surface morphology and elemental composition, combined with the physicochemical properties of subcritical water, indicated that the desorption or thermal degradation of hydrocarbons adsorbed on the rock surfaces under the action of the subcritical water significantly alters their wettability characteristics. This research offers novel insights into the mechanisms driving wettability changes on high-temperature reservoir rock surfaces and supports the development of effective strategies for preventing water phase trapping and enhancing oil recovery.</div></div>","PeriodicalId":278,"journal":{"name":"Colloids and Surfaces A: Physicochemical and Engineering Aspects","volume":"716 ","pages":"Article 136753"},"PeriodicalIF":4.9,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143734520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The VB12/SS composite electrode proved to be the optimal for the synergistic effect of VB12 and metal substrate on the DCAA degradation. Target chloro-, bromo-, and iodo-HAAs were catalytically decomposed, and their dehalogenation efficiency and mechanistic pathway were compared. The results show that HAAs electrolytic dehalogenation rates were significantly related with both the degree of halogenation (tri &gt; di &gt; mono) and the halogen atomic weight (I &gt; Br &gt; Cl). Dehalogenation of HAAs follows a first-order kinetic model, and kinetic variations were well described by a linear model.

In this work, first-principles methods based on density functional theory (DFT) are employed to investigate the stability, electronic structure, and gas-sensing properties of Cr₂Pc and Mo₂Pc monolayers upon adsorption of five representative VOCs (C₂H₄, CH₃Cl, C₆H₆, H₂CO, and CH₃OH). The results reveal that Cr₂Pc monolayer exhibits weak adsorption for C₂H₄, CH₃Cl, and C₆H₆, while demonstrating moderate adsorption strength for H₂CO and CH₃OH.

Furthermore, a comprehensive evaluation of sensitivity and recovery time suggests that two-dimensional Cr₂Pc is a promising reusable CH₃OH gas sensor at room temperature, featuring an ultrafast recovery time of 0.14 s and resistance to interference from common gases such as H₂O, N₂, CO₂ and CH₄.
