| 中文摘要 | the effects of the chain structure and the intramolecular interaction energy of an a/b copolymer on the miscibility of the binary blends of the copolymer and homopolymer c have been studied by means of a monte carlo simulation. in the system, the interactions between segments a, b and c are more repulsive than those between themselves. in order to study the effect of the chain structure of the a/b copolymer on the miscibility, the alternating, random and block copolymers were introduced in the simulations, respectively. the simulation results show that the miscibility of the binary blends strongly depends on the intramolecular interaction energy ((ε) over bar (ab)) between segments a and b within the a/b copolymers. the higher the repulsive interaction energy, the more miscible the a/b copolymer and homopolymer c are. for the diblock copolymer/homopolymer blends, they tend to form micro phase domains. however, the phase domains become so small that the blend can be considered as a homogeneous phase for the alternating copolymer/ homopolymer blends. furthermore, the investigation of the average end-to-end distance ((h) over bar) in different systems indicates that the copolymer chains tend to coil with the decrease of (ε) over bar (ab) whereas the (h) over bar of the homopolymer chains depends on the chain structure of the copolymers. |
