摘要/Abstract

摘要： 利用自由基共聚合反应, 将丙烯酰胺( AM) 和( 2 - 丙烯酰氨基) 乙基十二烷基二甲基溴化铵( AMQC 1 2) 在水介质中制备一系列纯疏水缔合水凝胶( 简称 AQ系列疏水凝胶) 。拉伸和压缩实验结果表明, AQ疏水凝胶具有优异的机械力学性能。拉伸强度和压缩强度均随着单体浓度和疏水单体含量增大而提高; AQ - 2. 5 - 2 0的拉伸强度和压缩强度分别达到2 5 0k P a和1 4MP a, 并对应着18 5 0%和9 4%的高应变值, 说明 AQ疏水凝胶兼具高强度与高韧性。当撤去外力时, 试样的形状及力学性能参数瞬间回复到初始状态, 说明AQ疏水凝胶具有优异的弹性回复能力。

Abstract: A purely hydrophobically associating hydrogels were synthesized by the free radical copolymerization of acrylamide (AM) and dimethyldodecyl(2acrylamidoethyl)ammonium bromide (AMQC12) in water (named AQgels). Tensile and compressive results showed that AQgels exhibited excellent mechanical properties. The tensile and compressive strengths were increased with the increment of monomer concentration and hydrophobe content. The tensile and compressive strengths of AQ2.520 were about 250 kPa and 14 MPa, respectively. It should be noted that AQgels possessed both high strength and high toughness, which was validated by the tensile breaking elongation of 1 850% and compressive breaking elongation of 94%. Furthermore, AQgels had excellent elastic recoverability because the shapes and mechanical properties recovered instantaneously when the added force disappeared.
