We found that microphase separation takes place in semidilute solutions of various kinds of block copolymers using common solvent, such as toluene, tetrahydrofuran, dioctylphthalate, diisopropylbenzene, benzene, etc and non-solvent, such as methanol, cyclohexane, octane, decane, tetradecane, etc. It was also found that selectivity was effectively controlled by temperature change to induce microphase separation in semi-dilute solutions. This technique allowed us to observe the grain formations in detail.

我们发现，在常用溶剂（如甲苯、四氢呋喃、邻苯二甲酸二辛酯、二异丙苯、苯等）和非溶剂（如甲醇、环己烷、辛烷、癸烷、十四烷等）中，各种嵌段共聚物在半稀溶液中均发生微相分离。这种技术使我们能够详细观察颗粒的形成。
