Description

論文(Article)

Structure and characterization of the cast films of polyvinylpyrrolidone (PVP) and polyvinylalcohol (PVA) were investigated experimentally. As a result, a particular relationship between the conditions of casting velocity, blend ratio, and heat treatment was found. Further an existence of special value zone of them for appearing new kind of phase separation phenomena of the stratum such as gradient or step structure was also found.
