| 中文摘要 | a cationic surfactant monomer, dimethyldodecy1(2-acrylamidoethypammonium bromide (amqc(12)) was synthesized. a family of hydrophobic-associating cross-linking hydrogels (hac-gels) fabricated via the self-assembly of amphiphilic multiblock copolymers of acrylamide and amqc-12 can be synthesized by free-radical aqueous solution micelle copolymerization in the absence of surfactants using the one-pot method. the hac-gels possessed outstanding mechanical performance, with optimal tensile strength, compressive strength, and elongation at break of 250 kpa, 14 mpa, and 1850%, respectively. meanwhile, the hac-gels exhibited self-healing property, and tetrahydrofuran (thf) significantly accelerated their self-healing process. the recovery hysteresis of hydrophobic-associating hydrogels prepared in the presence of surfactants can be eliminated because of homogeneity of the hydrogel network and the dynamic and mobile properties of physical cross-linking junctions. investigations on the mechanical property and structure evolution of hydrogels revealed that the hydrophobic-associating interaction was the driving force of self-assembly of amphiphilic multiblock copolymers. furthermore, spherical micelles and macroscopic cross-linking network can be easily switched reversibly by regulating copolymers concentration.
