一种纯疏水缔合凝胶的制备及性能研究
Preparation and Charaction of a Purely Hydrophobically Associating Hydrogels
摘要
Abstract
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.关键词
