Surface phase separation between polythylene oxide of different molecular weight

ORAL

Abstract

In-plane phase separation of polyelethylene oxide of different molecular weight has been observed. A systematic investigation on a broad range of Mw show that the process is originated from the conformatinal entropy for a polymer confined on a surface (thin film).
