A molecular dynamics simulation is performed to study the kinetics of microphase separation in a polymer-dispersed-liquid-crystal forming process. An equimolar mixture of monomers and liquid crystal molecules are thermalized in a well mixed state. The monomers are then polymerized at the same temperature. The end product is a spanning gel with liquid crystal molecules aggregating in droplets here and there. The peak position of the equal-time structure function suggests that the growth of the droplets may be described with t(-0.23). The small growth exponent is just one of several features which may be attributed to the growing elastic gel. We argue that the aggregation is driven by entropy.
进行了分子动力学模拟，以研究聚合物分散液晶形成过程中的微相分离动力学。单体和液晶分子的等摩尔混合物在充分混合的状态下热化。然后单体在相同温度下聚合。最终产物是一种贯穿的凝胶，液晶分子聚集成四处分布的液滴。等时结构函数的峰值位置表明液滴的生长可以用t(-0.23)来描述。小的生长指数只是可归因于生长中的弹性凝胶的几个特征之一。我们认为聚集是由熵驱动的。
