However, their practical utility is hindered by challenges related to the high surface tension and susceptibility to oxidation, leading to poor wettability on hydrophilic substrates. In this study, we present an approach to significantly improve the surface wettability of liquid metals on hydrogels, facilitated by poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS). Through strong polymer chain entanglements, PEDOT:PSS is capable of adsorbing onto the surface of prestretched hydrogels, thereby providing a robust infiltration substrate for liquid metals. Even when immersed in an aqueous solution with a pH of 4–7, liquid metals can be firmly adhered to the PEDOT:PSS surface for up to 30 days. The remarkable infiltration capability of PEDOT:PSS, combined with liquid metals, enables the formation of continuous and stable conductive pathways on the hydrogel surfaces. The resulting conductive hydrogels exhibit different sensitivity factors in three different stretch ratio ranges for various applications in soft electronic systems.

In this study, a preparation method for one-component epoxy resins was proposed, which is highlighted by the excellent storage stability, feasibility, renewability of feedstocks, and enhanced thermal resistance of the cured resin. Specifically, the curing system was composed of aromatic bismaleimide, lignin-derived triarylimidazole, and commercially available epoxy prepolymers. During the mixing stage, the electron-rich imidazole interacted with the electron-deficient maleimide, resulting in the formation of complexes through dipole interactions and π-π stacking. This interaction effectively sequestered the nucleophilic lone pair electrons and electrophilic epoxy groups, significantly improving the storage stability of the curing system at ambient temperature without the need for prepreparation of latent curing agents. As the temperature increased, the weak interactions diminished, releasing the active imidazole, which initiates the homopolymerization of the bismaleimide component and the epoxy component as well as their copolymerization. Consequently, a hybrid network that incorporates both bismaleimide and epoxy resins, with lignin-derived triarylimidazole serving as the linkages, was formed. The bismaleimide resin component substantially enhanced the thermal resistance of the hybrid resin, achieving a lap-shear strength of 3.31 MPa at 250 °C.

In this study, a phenylsilane/tri-piperazine phosphate-based cross-linked aggregate (MPNSI) was employed as a char-forming flame retardant for thermoplastic vulcanizate (TPV). Compared to the conventional linear piperazine pyrophosphate (PAPP), the aggregate MPNSI with the integration of phosphorus, nitrogen, and silicon-based groups significantly had a higher flame retardant performance in the elastomer. Specifically, a 20 wt % loading of the MPNSI/melamine polyphosphate (MPP) blend enabled TPV to achieve a UL-94 V-0 rating at 3.2 mm thickness, compared to 23 wt % required for the PAPP/MPP system. Furthermore, 23 wt % MPNSI/MPP endowed TPV with a UL-94 V-0 rating in the test of a 1.6 mm thickness sample, whereas the PAPP-based formulation failed to pass. The limiting oxygen index was also significantly increased through the MPNSI system. In the cone calorimeter test, MPNSI/MPP with a 23 wt % dosage achieved a 78.0% reduction in the peak heat release rate and a 66.5% reduction in the peak smoke production rate. Beyond flame retardancy, the incorporation of the MPNSI-based system had minimal impact on the mechanical properties of TPV. Notably, the 23 wt % MPNSI/MPP formulation retained a 89.5% level of elongation at break of neat TPV, thus preserving the essential elastomeric characteristics required for functional applications. These findings demonstrate the promise of phenylsilane/tri-piperazine phosphate-based aggregates as an effective strategy for achieving high-performance flame retardancy while maintaining mechanical integrity in elastomers.</p>","PeriodicalId":7,"journal":{"name":"ACS Applied Polymer Materials","volume":"7 17","pages":"11951–11961"},"PeriodicalIF":4.7,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145036455","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}
