Dynamic hydrogels have attracted considerable attention in the application of flexible electronics, as they possess injectable and self-healing abilities. However, it is still a challenge to combine high conductivity antibacterial properties into dynamic hydrogels. In this work, we fabricated type hydrogel based on acylhydrazone bonds between thermo-responsive copolymer silver nanoparticles (AgNPs) functionalized with hydrazide groups. The hybrid exhibited sol–gel transition, self-healable, efficiency was over 92%. Moreover, displayed antimicrobial (6.85 S/m). Notably, hydrogel-based sensors strain temperature sensing (22.05%/°C) could detect human motion speech, electrocardiographic (ECG) electromyography (EMG) signals. Overall, work provides simple strategy synthesize AgNPs-based multi-functions, may find potential applications wearable health monitoring speech recognition.

Abstract In this study, the synthesis and characterization of poly(ethyl methacrylate‐ co ‐acrylamide) (i.e., poly(EMA‐ ‐AAm)) nanogels loading release studies doxorubicin hydrochloride were carried out. The was out using emulsion polymerization technique at 60 °C. Swelling experiments showed that sensitive to temperature pH medium. Zeta sizer analysis results synthesized had an average size 23.17 nm PDI value 0.270. into nanogels, drug capacity (DLC) nanogel determined as 32% efficiency (DLE) 77%.
