Structure and permeation properties of cellulose esters asymmetric membranes.

The permeation properties of a series of membranes of cellulose esters, presenting a wide range of characteristics, were studied and correlated to the structure of water in the pores, to the polymer hydrophilicity/hydrophobicity, and to the morphology of the surface of the active layer. Asymmetric membranes of cellulose acetate, cellulose acetate propionate… (More)
