Polyprotein Cross-linked Hydrogels with High Stretchability, Fracture Toughness and Low Hysteresis LIU Dongsheng* Key Laboratory of Bioorganic Phosphorus Chemistry & Chemical Biology, Department of Chemistry, Tsinghua University, Beijing 100084, P. R. China Abstract It is challenging to realize both high fracture toughness and low hysteresis perfectly in synthetic systems, which restricts the use of stretchable hydrogels in load-bearing applications. Recently, by imbedding the folded polyprotein cross-linker in a percolating random coiled network, Cao et al. demonstrated a highly stretchable hydrogel, which shows low hysteresis(
