Under the tested short-term room-temperature conditions, the lower-concentration NaOH solutions produced lower corrosion and passive current densities and higher interfacial impedance than the higher-concentration solutions. The chemical composition and valence states of the passive film were not directly determined in the present study; therefore, the possible roles of Cr- and Mn-containing surface species are discussed only as literature-informed interpretations.

In this work, mesoporous silica nanoparticles (MSNs) were developed as pH-responsive nanocarriers, for controlled corrosion-inhibitor release. Two MSN architectures were synthesised: hexagonally ordered mesopores (MSNs-hex) and centre–radial hierarchical porosity (MSNs-CR), providing tunable loading capacity and release kinetics. Polyacrylic acid (PAA) and polyethylenimine (PEI) were employed pH-responsive polymer gatekeepers under acidic-to-neutral and alkaline conditions, respectively. Benzotriazole (BTA), used as a conventional corrosion inhibitor, and caffeine (CAFF; 1,3,7-trimethylxanthine), selected as an environmentally more benign alternative, were loaded into the nanocarriers, and their release behaviour was systematically investigated. MSNs-CR architectures achieved higher inhibitor loading than MSNs-hex, approximately 6.5 and 1.3 wt%, respectively, confirming the enhanced cargo capacity of the hierarchical architecture. Functionalisation with PAA or PEI enabled pH-dependent release under neutral and alkaline conditions, respectively, with PEI-gated MSNs-CR releasing nearly 90% of both inhibitors over 48 h at pH 11. BTA and CAFF displayed comparable normalised release profiles, although a lower absolute amount of CAFF was incorporated and retained. Preliminary ageing tests on bronze showed a stronger protective effect for BTA, while CAFF still reduced surface oxidation relative to the uncoated aged substrate. Overall, this study establishes a versatile, stimuli-responsive platform integrating hierarchical pore engineering and polymer gating to control inhibitor loading and release, with promising potential for sustainable corrosion-protection applications.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"61 44","pages":"35035 - 35056"},"PeriodicalIF":4.4,"publicationDate":"2026-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10853-026-13748-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149163014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, inorganic fiber-based insulation boards were fabricated via mechanical compression molding to systematically evaluate the effects of silica sol and alumina sol as binders on material properties. The influence of mixed sol ratios (alumina/silica) on the structural and functional performance of the fiberboards was further investigated. The results demonstrate that fiberboards prepared with alumina sol exhibit significantly enhanced physical properties at room temperature, with compressive strength increases ranging from 74.6% to 331.0% compared to those using silica sol. Conversely, the alumina-based boards show reduced high-temperature stability and thermal insulation performance. By employing mixed sol systems, the complementary advantages of both binders can be partially integrated. With increasing alumina sol content in the hybrid system, the microstructure and overall performance progressively approach those of the pure alumina system. Accordingly, this study establishes that tailoring the type and proportion of composite sol enables directional property design for fiberboards, thereby providing a viable strategy to meet specific application requirements across diverse thermal environments.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"61 44","pages":"34971 - 34987"},"PeriodicalIF":4.4,"publicationDate":"2026-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149163079","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}

Driven by the pronounced energy-level mismatch between the polymer host and AN dopants, customized localized deep electron traps (~1.25 eV) are constructed. Under coupled electro-thermal stresses, this tailored electronic landscape efficiently captures nonequilibrium hot carriers, effectively suppressing long-range hopping transport and significantly reducing conduction loss.
