摘要：
Using polyethylene glycol(PEG) or glycerol as the plasticizer, we synthesized the hydrogels from poly(ethylene glycol) diacrylate(PEGDA), polyvinylpyrrolidone(PVP) and poly(vinyl alcohol)(PVA) under UV radiation. The effects of different plasticizers on the mechanical properties and adhesion properties of the hydrogels were investigated. The results show that the plasticizer can improve the elongation and peeling force. The most pronounced changes in the tensile property of the hydrogels are due to the addition of glycerol followed by PEG, the lower the plasticizer's molecular weight, the greater its effect. The maximum peeling force is 0.317 or 0.257 N with PEG or glycerol as plasticizer, respectively, and their adhesion properties are due to the formation of hydrogen bonds.
