SYNTHETIC SELF-ASSEMBLED HYDROGELS WITH HIGHLY MECHANICAL AND RECOVERABLE PROPERTIES:A HOMOGENEOUS NETWORK DESIGN

摘要：

　　Development of hydrogels with high mechanical and recoverable properties under physiological conditions is of great importance for broadening and improving their potential applications in load-bearing artificial soft tissues.Inspired by the self-assembly of chemistry entities,herein,we synthesized homogeneous network hydrogels containing over 90 wt%of water,resulting from covalent cross-links of poly(vinyl alcohol)(PVA)and poly(vinyl pyrrolidone)(PVP)triggered by microwave-assisted treatment.A structurally homogeneous network results in an evenly distributed stress that endure high strains with minimal energy dissipation,which enable the hydrogels to withstand up to 1.16 MPa of tensile stress,over seven-fold of stretch length with negligible hysteresis,and sustain cyclic compression following high amplitude deformation.It is of importance for tissue replacement that the hydrogels retain these excellent properties under physiological conditions.
