Polyvinyl　alcohol　(PVA)　is　a　polymeric　material　with　good　biocompatibility,　excellent　hydrophilicity,　and　a　large　number　of　hydroxyl　groups.　However,　due　to　its　insufficient　mechanical　properties　and　poor　inhibition　of　bacteria,　it　has　a　lack　of　applications　in　wound　dressings,　stent　materials,　and　other　fields.　In　this　study,　a　simple　method　was　used　to　prepare　composite　gel　materials:　Ag@MXene-HACC-PVA　hydrogels　with　a　double-network　structure　were　prepared　using　an　acetal　reaction.　Due　to　the　double　cross-linked　interaction,　the　hydrogel　has　good　mechanical　properties　and　is　resistant　to　swelling.　The　adhesion　and　bacterial　inhibition　were　enhanced　due　to　the　addition　of　HACC.　In　addition,　the　strain　sensing　properties　of　this　conductive　hydrogel　were　stable,　and　the　GF　(specification　factor)　was　1.7617　at　40–90%　strain.　Therefore,　the　dual-network　hydrogel　with　excellent　sensing　properties,　adhesion　properties,　antibacterial　properties,　and　cytocompatibility　has　potential　applications　in　biomedical　materials,　especially　as　a　tissue　engineering　repair　material.　©　2023　by　the　authors.
