Abstract
A toluene solution of styrene/cellulose graft copolymer which had been prepared by using cellulose gel as an substrate was dispersed in an excess of water. Then the system was allowed to stand for hours at room temperature to be transformed into macroscopic two phases which consist of a transparent toluene phase and a clear water phase. The toluene of the former phase was evaporated with the intention of preparing the film containing toluene-water interface.
Static contact angles of the films against deionized water revealed that the surface of the water phase side of the film was covered with cellulose.
