| 2 | Super-anti-freezing,tough and adhesive titanium carbide and L-ornithine-enhanced hydrogels显示文摘Hydrogels are highly porous three-dimensional crosslinked polymer networks consisting of hy-drophilic polymers,employed most practically in medicine and industry,often as biosensors.Simple hydrogels suffer limitations in their mechanical properties,such as tensile and com-pression,and freeze at sub-zero temperatures,which compromise their ability as useful biosen-sors.In this study,the incorporation of L-ornithine-based zwitterionic monomer(OZM),titanium carbide(MXene),and glycerol within polyacrylamide hydrogels was used to prepare a novel polyacrylamide/polyL-ornithine-based zwitterion/MXene(PAM/Porn/MXene)hydrogel to im-prove the mechanical,adhesion,and anti-freezing properties of pure polyacrylamide hydrogels.This study also analyzed the mechanical strength(tensile and compression),adhesion,and anti-freezing properties of a novel PAM/Porn/MXene hydrogel at 1%,4%,and 10%MXene concen-trations to establish to what extent the conductive MXene material enhanced these properties and concluded that the tensile and compressive properties improved linearly with the increase in the concentrations of MXene,adhesion decreased with the increased MXene concentrations,and syn-ergistic interaction between MXene and OZM significantly improved the anti-freezing properties up to-80°C. | Zhangkang Li Jamie LeBlanc Hitendra Kumar Hongguang Zhang Weijun Yang Xiao He Qingye Lu Jeffrey Van Humbeck Keekyoung Kim Jinguang Hu | 2023 | Journal of Bioresources and Bioproducts2023，8，2： | 0 |
