Abstract

A water stable nanocellulose film was prepared and used as a template for functional membrane material. A simple method to considerably improve water stability of 2,2,6,6-tetramethylpiperidin-1-yl)oxy (TEMPO) oxidized cellulosic nanofibril films was applied. The method involved the use of a 10-25% of poly(vinyl alcohol) (PVA) as bridging agent in films, which were prepared by solvent casting without additional post-treatments. The influence of amount and degree of hydrolysis of PVA on mechanical properties of wet films was studied. Due to numerous functional groups on the surface of the water stable, porous film, it could be used as a template for functional membrane materials with respect to ion capturing. Further functionalization of the film surface could be done by grafting thermoresponsive poly(N-isopropylacrylamide) (PNIPAM) to pursue improved control over hydrophilicity of the surface for antifouling purposes.
