Transport of solutes through calix[4]pyrrole-containing cellulose acetate films
Valente, A. J. M.; Jiménez, A.; Simões, A. C.; Burrows, H. D.; Polishchuk, A. Ya.; Lobo, V. M. M.Films of cellulose acetate containing different concentrations of meso-octamethyl-porphyrinogen (calix[4]pyrrole) were prepared and characterized using UV-vis and FTIR spectroscopy, DSC and SEM. Incorporation of calix[4]pyrrole into cellulose acetate leads to a decrease in the degree of hydrophilicity of the polymeric matrix. However, a slight increase in the percentage of water uptake of the polymer is found w...
