Preliminary Investigation into Thermal and Mechanical Properties of Ionically Cross-linked Cellulose Nanofibril Films

Abstract

This work describes the manufacturing process of optically clear films from cellulose nanofibril (CNF) materials, as well as sequential exchange of Na ions present in CNF with a variety of different metallic ionsAl, Fe, Ba, Cu, Znin an attempt to improve mechanical properties. Successful substitution of a Na ion in starting material was verified by use of X-ray photoelectron spectroscopy. Effects of ion exchange/cross-linking on the films were evaluated using thermogravimetric analysis and tensile-strength measurements. It was shown that tensile strength and toughness increase when divalent cations are used for exchange (Ba, Cu, Zn), while exchanging sodium for trivalent cations (Al, Fe) produces detrimental effects on films mechanical properties.
