| 中文摘要 | the gelation of physically associating triblock copolymers in a good solvent was investigated by means of the monte carlo simulation and a gelation process based on the conformation transition of the copolymer that was described in detail. in our simulative system, it has been found that the gelation is closely related with chain conformations, and there exist four types of chains defined as free, dangling, loop, and bridge conformations. the copolymer chains with different conformations contribute to the formation of gel in different ways. we proposed a conformational transition model, by which we evaluated the role of these four types of chains in sol-gel transition. it was concluded that the free chains keeping the conformation transition equilibrium and the dangling conformation being the hinge of conformation transition, while the chain with loop conformation enlarges the size of the congeries and the chain with bridge conformations binds the congeries consisted of the copolymer chains. in addition, the effects of temperature and concentration on the physical gelation, the association of the copolymer congeries, and the copolymer chain conformations' distribution were discussed. |
