▎ 摘  要

NOVELTY - Preparing anti-freeze self-repairing conductive hydrogel comprises preparing composite hydrogel, soaking prepared composite hydrogel in the composite modifier solution, where the composite hydrogel is conductive nano-filler/nano-cellulose/polyacrylamide hydrogel and composite modifier solution is mixed metal salt in antifreeze water system. USE - The method is useful for preparing anti-freeze self-repairing conductive hydrogel. ADVANTAGE - The method: can reduces the freezing point of water in composite hydrogel network structure and improves its frost resistance; uses metal cations and cellulose in the composite hydrogel form reversible ionic bonds, and cellulose and polyacrylamide form reversible hydrogen bonds, forming multi reversible and ensures that the network endows the prepared hydrogel with excellent self-healing properties; and uses metal salt, which cooperates with the conductive nanofiller to obtains the prepared hydrogel with excellent conductivity, and has sensitive sensing performance and mechanical flexibility to meet the requirements of corresponding application scenarios. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for freeze-proof self-repairing conductive hydrogel, is prepared by the preparation method.
