Antimicrobial polymer composite materials are disclosed that are suitable for making oral devices used in dental applications, such as denture bases. Acrylic resin composite materials comprising antimicrobial polymers and antimicrobial fillers provide reduction in common oral microorganisms after long-term aging, with reduced release rate of antimicrobial agents from the composite material. Antimicrobial polymers are prepared from compositions comprising acrylate and/or methacrylate monomers and polymerizable quaternary ammonium silicon-containing compounds.

A reversible stress-responsive material, a preparation method, and a use thereof are provided. The reversible stress-responsive material prepared by the present disclosure has the property of real-time reversible force response at room temperature. When used with crosslinked plastic (high Tg) and rubber (low Tg) polymer materials, the reversible stress-responsive material can significantly enhance the mechanical strength and ductility of covalently cross-linked polymers. In the present disclosure, the triazolinedione (TAD)-indole click chemistry with the force-induced reversible property is used to construct a force-reversible crosslinked polymer material, and such a force-induced reversible crosslinking method can achieve the breakage and re-forming of covalent crosslinking points at room temperature in a solid state without any external stimuli other than the ambient temperature. This room-temperature force-induced reversible C—N covalent crosslinking can be regarded as an innovative approach to designing a high-toughness polymer material.
