中文摘要: 通过考察不同单体浓度或离子强度下凝胶的力学性能和溶胀特性，对聚2-丙烯酰胺-2-甲基丙磺酸（PAMPS）与聚丙烯酰胺（PAAm）形成的互穿网络凝胶的高强度性能和作用机理进行了研究。结果表明：PAMPS-PAAm互穿网络凝胶的力学强度对c(AMPS)存在一个最佳值(1 mol/L)，且随c(AAM)的增大而显著增大（0.5~4 mol/L）。当c(AMPS)=1 mol/L、c(AAM)=4 mol/L时，互穿网络凝胶的最大抗压强度达6.46 MPa；改变凝胶体系内水的离子强度，PAMPS-PAAm凝胶在0.25 mol/kg离子强度时的抗压强度与纯水状态下相比增加了29%。

Abstract:The properties and mechanism of high-strength interpenetrating polymer network hydrogel, which was synthesized by 2-acrylamide-2-methylpropane sulfonic acid and acrylamide, were studied according to their mechanical and swelling experiments under different monomer concentrations and ionic strength. Results show that the strength of PAMPS PAAm interpenetrating polymer network hydrogel increases with the increasing of AAm concentration (0.5-4 mol/L)，while the AMPS concentration has a optimal value (1 mol/L) and the highest compressive strength of the interpenetrating polymer network hydrogel is up to 6.46 MPa with 1 mol/L AMPS and 4 mol/L AAm. The compressive strength of PAMPS-PAAm hydrogel increases by 29% when increasing the ionic strength of the water in hydrogels to 0.25 mol/kg compared to deionized water.
