On the relationship between fibre composition and material properties following periodate oxidation and borohydride reduction of lignocellulosic fibres

摘要: Periodate oxidation followed by borohydride reduction was performed on four structurally different pulp fibres to clarify the effect of chemical composition structural and mechanical properties sheets made from these fibres. The main purpose explore possibility extending use lignocellulose in novel applications. degree oxidation, morphological changes, physical structure fibres, supramolecular ordering cellulose performance handsheets were studied. results showed that both periodate are more reactive towards carbohydrates as a result, there is an improvement tensile sheets. If only oxidised produce dialdehydes, inter- intra-fibre crosslinks can be formed, leading paper with increase strength higher stiffness. papers greater ductility. It also found characteristic ductility modified papers, emanating dialcohol produced, limited lignin-rich
