The use of humidity-sensitive materials exhibiting dual capacitance/resistance response characteristics offers a promising strategy to enhance sensor applicability. In this study, a chitosan humidity sensor was developed to systematically investigate its dual-response behavior under varying humidity conditions (6%–92%RH). Sensors with different interdigitated electrode configurations were fabricated and characterized at 1 kHz to evaluate their humidity sensing performance. Experimental results demonstrate outstanding sensor performance, including high response (5382.29% in capacitance and 99.99% in resistance) and rapid response/recovery times (within 10 s and 30 s, respectively). Among the configurations tested, the interdigitated electrodes design exhibits the most pronounced capacitance response, accompanied by a notable resistance response and the fastest response/recovery times, establishing it as the optimal electrode structure. The dual-response mechanism was elucidated using a water adsorption model, revealing distinct capacitance and resistance behaviors, while different electrode configurations modulate ion transport pathways and electric field distribution, accounting for the observed performance differences. Non-contact sensing tests further validate the practical potential of the dual-response characteristics. These findings provide valuable insights for optimizing the design and expanding the applicability of advanced humidity sensors.","PeriodicalId":18477,"journal":{"name":"Materials Today Communications","volume":"53 1","pages":"115285-115285"},"PeriodicalIF":0.0,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147878092","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}

Liu, Yu Li","doi":"10.1016/j.mtcomm.2026.115048","DOIUrl":"https://doi.org/10.1016/j.mtcomm.2026.115048","url":null,"abstract":"Epoxy resin-hollow glass microsphere composites (EHC) exhibit low density and excellent mechanical properties, making them promising candidates for marine/aerospace applications. However, their high flammability severely restricts broader use. To improve flame retardancy while maintaining low density, ammonium polyphosphate-coated hollow glass microspheres (APP-HGM) were utilized to fabricate flame-retardant epoxy composites (EAHC). EAHC achieved improved flame retardancy and maintained low density, but it suffered from insufficient flame-retardant efficiency and notable mechanical degradation. To address these drawbacks, SmMn 2 O 5 mullite nanoparticles (SMO) were further incorporated to fabricate the multi-component flame-retardant epoxy composite (SMO-EAHC). Systematic characterizations including thermogravimetric analysis (TG), limiting oxygen index (LOI), vertical burning (UL-94) and cone calorimeter test confirmed that APP-HGM serves as both a flame-retardant filler and a lightweight matrix component, while SMO catalyzes the decomposition of APP and promotes the formation of compact char layers. SMO-EAHC achieved a LOI of 27.6% and a UL-94 V-1 rating, and presented remarkable reductions of 58.81%, 38.67%, 73.65% and 62.96% in peak heat release rate (pHRR), total heat release (THR), peak smoke production rate (pSPR) and total smoke production (TSP) compared with unmodified EHC. Meanwhile, SMO-EAHC exhibited a compressive strength of 23.84 MPa, representing a 32.08% improvement relative to EAHC, while maintaining a low density of 0.66 g/cm³. In summary, this work proposes a targeted two-step modification strategy, involving APP-HGM functionalization followed by SMO complementation, to address the flammability of EHC. This strategy realizes the balanced integration of flame retardancy, lightweight characteristic and pressure resistance, providing technical support for the application of polymer composites in extreme environments. • Prepare SMO-EAHC by integrating APP-HGM and SmMn₂O₅ into modified epoxy. • SMO catalyzes APP decomposition, consolidates char layer. • SMO-EAHC attains LOI 27.6% (UL-94 V-1), 58.81% pHRR & 73.65% pSPR cuts vs EHC. • Retains low density (0.66 g/cm³) and high pressure resistance (23.84 MPa). • Offers technical support for flame-retardant composites in marine/aerospace.","PeriodicalId":18477,"journal":{"name":"Materials Today Communications","volume":"52 1","pages":"115048-115048"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147880376","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 work, TiO 2 nanotubes (TiO 2 -NTs，TNT) with well-morphology and high {001} facets exposure ratio were directly synthesized by H 3 PO 4 /HF-assisted two-step anodic oxidation. The results show that the addition of 3 wt% H 3 PO 4 and 0.5 wt% HF into the electrolyte facilitates the preparation of TiO 2 -NTs with an average crack density of 0 % and {001} facets exposure ratios up to 80.00 %. Moreover, the PO 4 3- and HPO 4 2- in the anode effectively hinder the generation of electron current and release of oxygen bubbles on the surface of Ti substrate, which reduces the surface cracks of TiO 2 -NTs. The F - in the electrolyte is adsorbed on the {001} facets of the TiO 2 -NTs, which decreases the energy of the O-Ti-O, thus achieving the purpose of high {001} facets exposure ratio. Ultimately, the excellent optical properties, in conjunction with the synergistic effect of {001} facets-selective orientation and O V , significantly enhanced the photocatalytic activity of TiO 2 -NTs, resulting in the removal of 90.32 % Rhodamine B in 120 min under visible light illumination.

In this study, we present a multifunctional polyacrylamide-based interfacial evaporator (CAP) that integrates in situ synthesized carbon nanotubes/silver nanoparticles (CNTs/AgNPs) composites. The AgNPs exhibit robust antibacterial activity, while the CNTs contribute to broadband photothermal absorption. The hydrogel matrix features tunable crosslinking density, which is optimised to facilitate water mobility and reduce the evaporation enthalpy. In conditions of illumination from a single sun, the CAP demonstrates a high evaporation rate of 2.3 kg·m -2 ·h -1 , exhibiting exceptional resistance to biofouling and salt crystallisation. Furthermore, the CAP produces freshwater with ion concentrations below 1 ppm, meeting WHO drinking standards.

However, it is highly susceptible to atomic oxygen (AO) erosion, which severely limits the service lifetime of spacecraft. Herein, a dual-protection (matrix modification and coating) strategy is proposed to improve the anti-AO capacity of PI by introducing rectorite nanosheets (RNs) with outstanding AO resistance. The dual-protected rectorite/PI film shows lower AO erosion yield (only 4.04% of the pristine PI film) and more stable mechanical properties after AO irradiation. The AO-resistant mechanism is attributed to the blocking and adsorbing AO of RNs based on the experiment investigation and molecular dynamic simulation. The key advantage of this method is that, even if the coating is compromised, the RNs embedded in the matrix can still provide resistance against AO erosion. Consequently, this protection strategy provides a new approach for constructing superior AO-resistant PI films applicable in LEO conditions. • Rectorite nanosheets are simply and quickly fabricated by ball milling • Dual-protected rectorite/polyimide films show exceptional atomic oxygen resistance • The advantages of the dual-protection strategy are thoroughly explored • The blocking and adsorbing mechanisms of rectorite nanosheets are deeply revealed","PeriodicalId":18477,"journal":{"name":"Materials Today Communications","volume":"50 1","pages":"114587-114587"},"PeriodicalIF":0.0,"publicationDate":"2025-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147331874","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}
