Research Abstract

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.
