Abstract
The inferior mechanical performance and low conductivity limit the applications of hydrogels particularly in flexible electronics and tissue engineering. In this study, a highly robust and conductive hydrogel is fabricated through unique strategy of high-functionality crosslinker. The reduced graphene oxide (RGO) and chitosan (CS) act as the high-functionality crosslinker and bridge the polymers without involving any organic crosslinker. Chitosan (CS) is added for the reduction of graphene oxide (GO), while the ionic liquid (IL) facilitates the dispersion of RGO. Compared to the conventional PAA and CS hydrogels that use organic crosslinkers, the as-prepared composite hydrogel exhibits a significantly improved tensile strength. Interestingly, this technique can be used for application of coating on cotton fabric to improve its characteristics. Moreover, the sensing ability of high-strength hydrogel was also evaluated for applied strain. Based on this strategy, the mechanical properties and conductivity of the gel can be decoupled and separately tuned. The fabrication method in this work is facile and cost-effective, broadening its application in producing robust deformable electronics on bulk scale.
期刊介绍:
"Polymer Bulletin" is a comprehensive academic journal on polymer science founded in 1988. It was founded under the initiative of the late Mr. Wang Baoren, a famous Chinese chemist and educator. This journal is co-sponsored by the Chinese Chemical Society, the Institute of Chemistry, and the Chinese Academy of Sciences and is supervised by the China Association for Science and Technology. It is a core journal and is publicly distributed at home and abroad.
"Polymer Bulletin" is a monthly magazine with multiple columns, including a project application guide, outlook, review, research papers, highlight reviews, polymer education and teaching, information sharing, interviews, polymer science popularization, etc. The journal is included in the CSCD Chinese Science Citation Database. It serves as the source journal for Chinese scientific and technological paper statistics and the source journal of Peking University's "Overview of Chinese Core Journals."
