Abstract
The paper aims to determine the effectiveness of ethocel polymer, zinc oxide nanoparticles, and ethocel/ZnO nanocomposite for the consolidation of wooden paper pulp. Aged paper samples were treated with ZnO (0.5%,1%), ethocel (0.5%,1%), and ethocel loaded with ZnO NPs. The treated paper samples with the selected consolidated materials were submitted to artificial aging to evaluate their aging behavior. Visual examination, studying the paper morphology by SEM microscopy, FTIR-ATR analysis, colorimetric measurements, and determining the tensile properties were performed to study the morphological or chemical change that could occur due to consolidation or artificial aging. The data revealed that the consolidation treatment enhances the chemical stability of wood paper pulp. The data of yellowness and brightness reveals that the most effective treatment for decreasing the yellowness of aged paper is ZnO NPs, regardless of the effect of nano zinc on enhancing brightness properties; it has also been able to improve yellowness value. The results showed that ethocel loaded with nano zinc gave a noticeable improvement in the tensile properties of the aged wood pulp.
