In this study, in order to utilize the photoluminescent property of a conjugated polymer and the liquid crystal (LC) aligning property of a well-ordered comb-like poly(oxyethylene), we investigated blend surfaces of poly(3-hexylthiophene) (P3HT) and poly[oxy(n-decylsulfonyl methyl)ethylene] (CH3-10SE) mixtures. The morphology, compositions, and wettabilities of these blend surfaces were systematically analyzed as a function of the blend composition and were correlated with the alignment behavior of nematic LC on the blend surfaces. Therefore, we found that CH3-10SE part with a well-ordered side chain structure predominantly affects the both of wettability and LC alignment behavior of the blend films while there was no clear association between the wettability and the LC alignment behavior.
