基于简立方格点模型,对纳米粒子/共聚物混合体系进行了动力学Monte Carlo模拟研究. 每一共聚物链均由一个A珠子和三个B珠子组成,表示为A1B3. A1B3链的两亲性体现为B-B之间的相互吸引作用,同时憎水性的纳米粒子之间也存在相互吸引. 通过适当选取纳米粒子与B珠子之间的吸引作用势,观察到两种结构:纳米粒子/A1B3链的核-壳结构和纳米粒子分散在憎水壳层中的A1B3囊泡结构. 还研究了这两种结构的动力学演化过程,模拟结果表明在纳米粒子分散于囊泡壳层的过程中A1B3囊泡起模板作用.
Based on the simple lattice point model, the kinetic Monte Carlo simulations of the nanoparticle / copolymer hybrid system were performed. Each copolymer chain consisted of one A bead and three B beads, denoted A1B3. The amphiphiles of the A1B3 chain Sexual interaction is the mutual attraction between BBs, and there is mutual attraction between the hydrophobic nanoparticles.Selecting the attractive potential between nanoparticles and B beads, two structures are observed: nanoparticle / A1B3 chain Shell structure and nano-particles dispersed in the hydrophobic shell A1B3 vesicle structure also studied the dynamic evolution of the two structures, the simulation results show that the nanoparticles dispersed in the vesicle shell process A1B3 Vesicles play a role in the template.
