摘要
用自洽场理论方法(Self-consistent field theory,SCFT)计算了嵌段共聚物AB和三等臂星型均聚物A共混体系的微相形态.为了简化计算,着重讨论了固定嵌段共聚物本体的相形态(如层状相)时,所加入的均聚物的体积分数及均聚物与嵌段共聚物链长之比对体系相形态的影响;并结合体系的熵和相互作用能的变化,讨论了星型均聚物在体系微相结构中的分布.
The microphases of blend of AB diblock copolymer and 3-arm A star homopolymer were calculated by using self-consistent field theory （SCFT）. The lamellae phase of AB diblock copolymer melts was considered in order to simplify the calculation. It was found that the phase behavior of the blend depended on both the chain length and volume fraction of the star homopolymer. The distribution of star homopolymer within the microphases was investigated based on enthalpic and entropic effects.
