α-Cellulose-based films: effect of sodium lignosulfonate (SLS) incorporation on physicochemical and antibacterial performance

A homogeneous α-cellulose film was prepared by a regeneration method from ZnCl2/CaCl2/cellulose mixed system and further combined with sodium lignosulfonate (SLS) via crosslinking through intermolecular hydrogen bonds “bridge linkages”. The physicochemical antibacterial performance of films were investigated results showed that the modified exhibited stronger tensile strength, higher thermal stability, lower hydrophilic effect, better UV shielding as compared original one, especially, ability derived presence phenolic hydroxyl sulfonate groups in SLS. This study proposed simple sustainable for fabricating multifunctional environmentally friendly composite using two main lignocellulose resources raw materials.
