Abstract

Conductive hydrogels, with their excellent flexibility and tunable electrical conductivity, have shown broad application prospects in emerging fields such as flexible strain sensors and triboelectric nanogenerators (TENG). In this study, a conductive sodium carboxymethyl cellulose (CMC)/ polypyrrole (PPy)/polyacrylamide (PAM)(CPA) hydrogel was developed by integrating a CMC/PPy composite, synthesized via in situ polymerization, into a hydrophobic-associated polyacrylamide network. This hydrogel exhibits excellent mechanical properties, with a tensile strain as high as 1735%, demonstrating extremely high ductility and deformation capacity. The flexible sensor based on CPA hydrogel has a wide detection range (0%–500%) and can monitor the movements of various parts of the human body. In addition, the TENG assembled based on CPA hydrogel achieves stable electrical output performance, enabling it to power small wearable electronic devices and promote self-powered signal transmission, showing broad application prospects in the fields of intelligent human-machine interaction and wearable electronics.

期刊介绍： Chinese Journal of Polymer Science (CJPS) is a monthly journal published in English and sponsored by the Chinese Chemical Society and the Institute of Chemistry, Chinese Academy of Sciences. CJPS is edited by a distinguished Editorial Board headed by Professor Qi-Feng Zhou and supported by an International Advisory Board in which many famous active polymer scientists all over the world are included. The journal was first published in 1983 under the title Polymer Communications and has the current name since 1985. CJPS is a peer-reviewed journal dedicated to the timely publication of original research ideas and results in the field of polymer science. The issues may carry regular papers, rapid communications and notes as well as feature articles. As a leading polymer journal in China published in English, CJPS reflects the new achievements obtained in various laboratories of China, CJPS also includes papers submitted by scientists of different countries and regions outside of China, reflecting the international nature of the journal.
