Cluster Structure of the Surface of Plasticized Cellulose Triacetate Films

摘要

The influence of plasticizers,dibutyl phthalate and triphenyl phosphate,on the structure of the surface of cellulose triacetate films was studied.The parameters of an infinite cluster of the cellulose triacetate molecules on the film surface,the correlation radius delta of the spatial distribution of density,the degree rho_s of surface filling of the cluster,and the fractal dimensionality D,were calculated from the electron-microscopic data,using the cluster model.
