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(AMQC12)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-2.5-20的拉伸强度和压缩强度分别达到250 kPa 和14 MPa,并对应着1850%和94%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。

A purely hydrophobically associating hydrogels were synthesized by the free radical copolymerization of acrylamide (AM)and dimethyldodecyl (2-acrylamidoethyl)ammonium bromide (AMQC1 2 )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.
