CCPD-MPTES-CFs can maintain highly hydrophobic stability even without significant decrease in CAs after immersing in acid and base solutions for 21 days. Additionally, the clicked samples possess good self-cleaning property upon exposure to various liquids.

For this aim, the CPs coatings were electropolymerized and <em>in situ</em> electrodeposited from the corresponding monomers on the surface of PVA-NF collected on ITO electrodes, accomplishing the fibrous composites PVA@PEDOT and PVA@PPy. The assembly of CPs coatings on top of PVA-NF was characterized by FT-IR, FE-SEM and EDX elemental microanalysis, supporting the successful deposition of CP coatings. The electrochemical response of composites indicates that the redox properties of the CPs were preserved when deposited on the PVA-NF, and good capacitive behavior was displayed through 50 cycles of cyclic voltammetry. In addition, the PVA@CPs composites showed improved thermal resistance of at least 110 °C higher than the pristine PVA-NF. The evaluation of mechanical properties through stress-strain curves showed that incorporating PEDOT and PPy on the PVA improved Young's modulus to 95 MPa and 105 MPa, respectively, compared to pristine PVA-NF (61.4 MPa). Furthermore, the high water-solubility of the PVA-NF template leads to obtaining pure nanofibers of PPy and PEDOT at room temperature with preservation of microstructure at a high degree, being consistent with classical attributes associated with non-woven electrospun mats.

This study investigates the use of rice husk derived silica aerogel (SA) as a low-cost thermal insulation additive in commercial water-based acrylic paint. The highly porous SA with nanostructured closed pores significantly reduces thermal conductivity by effectively inhibiting heat transfer through the paint coating. The supercritically-dried SA was methyl-silanized to achieve a balance of hydrophobicity and maintain a high silanol density, enabling its compatibility within the water-based emulsion. The SA particles were directly added at 20, 40, and 60 vol% into the emulsion, followed by spray coating onto a bulk substrate resulted in a 1.3 ± 0.2 mm dry film thickness. The relationship between SA volume fraction on the paint properties was investigated through a comprehensive evaluation of aesthetic, mechanical, and thermal characteristics. The introduction of SA did not substantially alter the original paint color, although it increased surface roughness due to SA aggregation. These surface aggregates effectively impede heat transfer and contribute to the formation of a thermally insulating char layer during combustion. Concurrently, the combination of preserved SA porosity and surface hydrophobicity endowed the modified paint with low thermal conductivity (0.11–0.07 W/mK), high cohesive strength (1.3–2.7 MPa), and a high-water contact angle (θ° = 110°).</div></div>","PeriodicalId":20834,"journal":{"name":"Progress in Organic Coatings","volume":"201 ","pages":"Article 109114"},"PeriodicalIF":6.5,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143099326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
