Abstract

Abstract : The design of multiurea linkage segmented linear copolymers with tractable synthesis, processability, hybridization, and recyclability is reported in this work, having accessible handles with which fully swollen ultrastrong hydrogels or stretchable hydrogel fibers with nano‐, micro‐, or macroscale diameters can be produced via different manufacturing techniques including compression, solution casting, or spinning. Abstract : Strong and tough synthetic hydrogels have received ever‐increasing interests due to their potential applications as load‐bearing structural materials. However, strong, tough, and recyclable hydrogels in different forms that can be generated by different methods according to various practical applications still remain an intrinsic bottleneck. A simple one‐pot synthesis of multiurea linkage segmented linear copolymers with easy recyclability, hybridization, and processability, including compression molding, solution casting, and spinning methods, to yield ultrastrong and tough hydrogel films or stretchable hydrogel fibers with diameters ranged from macro‐, micro‐, to nanoscale, is reported here.
