Cluster Structure of the Surface of Plasticized Cellulose Triacetate Films

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 ξ of the spatial distribution of density, the degree ρ_s of surface filling of the cluster, and the fractal dimensionality D, were calculated from the electron-microscopic data, using the cluster model.__________Translated from Zhurnal Prikladnoi Khimii, Vol. 78, No. 2, 2005, pp. 306–309.Original Russian Text Copyright © 2005 by Novikov, Varlamov, Mnatsakanov.
