Zwitterionic polymer hydrogels have great application prospects in wearable electronic devices due to their antifouling and excellent biocompatibility. However, its strong hydrophilicity often leads easy swelling poor mechanical properties. In this study, aramid nanofiber (ANF)-reinforced zwitterionic ion were synthesized by the one-step free radical polymerization of N-acryloyl glycinamide (NAGA), N-[Tris (hydroxymethyl) methyl] acrylamide (THMA) sulfobetaine methacrylate (SBMA) monomers presence ANFs. A large number hydrogen bonds formed between amide groups ANFs NAGA units/the hydroxyl THMA sulfonic SBMA units, which improved internal interface force hydrogel. The obtained ANF-reinforced hydrogel had an anti-swelling property, ratio tensile strength 25% 170% those without addition By introducing lithium chloride as electrolyte improve conductivity subsequently assembling it into strain sensors, exhibited a high sensitivity (GF = 1.12), short response recovery times (100 ms 150 ms), cycling stability. This work provides feasible strategy for sensors.
