Feasibility of PVA-lignin as resin for nanocellulose future composites

Recently, cellulose fiber reinforced ecofriendly polymer composite for structural material is one of issue due to its sustainability, high mechanical properties, light weight and abundancy. For high strength and sustainable blend, a resin with sustainable, high strength and cellulose compatibility is demanded. PVA-lignin composite is one of good candidate for resin materials due to its high mechanical properties and good adhesion with cellulose. However, low waterproof ability is significant disadvantage of this material. In this paper, esterification reaction with maleic acid was adopted to enhance the mechanical properties. The esterification reaction enhanced waterproof ability and adhesion of PVA-lignin resin to cellulose material.
