This study focused on the preparation of anti-corrosion coatings on Q235 steel surfaces. Waterborne epoxy resin (WEP) served as the film-forming matrix, with SiO₂ and Al utilized as fillers. Three groups of samples, namely WEP, WEP/SiO₂, and WEP/SiO₂/Al, were prepared. The innovation was introduced in the coating preparation process, where silica sol was substituted for silica powder, effectively augmenting the dispersion of the silica filler within the WEP matrix. The coating morphologies were characterized using a metallographic microscope and scanning electron microscope (SEM). Results showed that compared to the WEP coating, the WEP/SiO₂/Al coating had fewer surface defects. For mechanical property evaluation, pencil hardness and adhesion tests were carried out. It was found that SiO₂ and Al synergistically boosted the pencil hardness of the WEP coating to a maximum of 4H while maintaining a similar adhesion grade to that of the WEP coating. Static water contact angle (WCA) tests indicated that the WCA values of WEP/SiO₂ and WEP/SiO₂/Al coatings were 79° and 81°, higher than that of the WEP coating (76°), and retained good hydrophobicity after 20 wear cycles. Electrochemical impedance spectroscopy tests revealed that the impedance value of the WEP/SiO₂/Al coating reached 2.17 × 10⁸ Ω cm², which is higher than that of the WEP/SiO₂ coating and the WEP coating. Moreover, its corrosion potential shifted positively by 248.8 mV compared to the WEP coating, signifying a significant enhancement in anti-corrosion performance. The excellent comprehensive performance of the WEP/SiO₂/Al coating can be attributed to the fact that SiO₂ and Al synergistically enhance the mechanical and anti-corrosion properties of the WEP coating.</p>\u0000 </div>","PeriodicalId":183,"journal":{"name":"Journal of Applied Polymer Science","volume":"142 25","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various molar ratios of SSA to CNF are examined, with the ratio represented as <i>x</i>, ranging from 0.2 to 1.0. Results indicate that the proton conductivity of the SCNF/SPEI composite membrane could be enhanced by creating the ionic path and hydrophilicity throughout the membrane.

For example, hydrogels with superior sealing properties often exhibit limitations such as conflict-free, individual, and flexible control over injectability and gel physical properties, as well as limitations regarding applications in diverse sealing scenarios. This article presents PL/OHA, a pH-driven injectable hydrogel sealant designed for wound sealing. PL/OHA employs dynamic bonds, including Schiff base and hydrogen bonds, to produce a biodegradable and biocompatible hydrogel sealant. By individually adjusting the pH value and solid content, the gelation time, mechanical properties, and adhesion strength of PL/OHA can be flexibly controlled to meet different requirements in various wound-sealing contexts. Experiments prove that the injection time of the hydrogel can be flexibly controlled, from several seconds to tens of minutes, by changing the pH value. It also exhibits adjustable mechanical properties. When the solid content of the hydrogel is increased from 24% to 36%, the tensile strength increases from 10.12 to 25.12 kPa, and the compressive strength increases from 97.50 to 516.61 kPa.

In response to existing challenges, a series of poly(styrene-block-isobutylene-block-styrene) (SIBS) block copolymers are evaluated for pIOL application, and methacryloyloxyethyl phosphorylcholine (MPC) is grafted onto SIBS to further improve its anti-adhesive properties in this work.

The analysis aims to quantify the impact of key parameters, including sealing interface design, O-ring pre-compression, and liner thickness, on overall sealing integrity. Through detailed modeling of the interactions among the metal boss, polymer liner, and sealing ring, the study shows that ignoring the viscoelastic response of the polymer liner can result in a significant underestimation of radial deformation, by a factor of 0.4–0.5. Furthermore, the increasing thickness of the liner wall in the vessel mouth area intensifies deformation within the sealing zone, thereby increasing the potential for leakage. The presence of an annular groove at the interface between the metal seat and polymer liner is critical for effective sealing, generating contact stresses that meet the operational requirements at 52 MPa. Moreover, the O-ring's sealing effectiveness is highly sensitive to the initial compression rate, achieving optimal performance at rates above 16%.
