基于界面相容性强化的木质素/高分子复合材料构筑策略
Construction strategies of lignin/polymer composite based on interface compatibility strengthening
摘要
Abstract
Lignin is the most abundant aromatic polymer in nature.The pulping industry produces millions of industrial lignin annually but high valorization is insufficient.Polymer materials are large in quantity and wide in range but usually come from non-renewable fossil resources which are difficult to degrade.Developing high-performance lignin/polymer composites is of practical significance in realizing the high-volume and high-value utilization of industrial lignin,reducing dependence on fossil resources and decreasing environmental pollution.However,the excessively strong intermolecular forces and easy-to-aggregate characteristics of industrial lignin lead to poor dispersion in polymer materials and result in low material properties.The review summarized recent strategies for improving the interfacial compatibility between lignin and polymers and divided the strategy into high-stress pulverization,compatible addition,chemical modification,aggregation adjustment and interface dynamic bond construction based on the micro-interface interactions.The review detailly evaluated the effects of lignin micro-interface structure and the connecting species with polymers on the strength and toughness of composite materials.It was pointed out that the interface compatibility strengthening was a critical issue for constructing advanced lignin/polymer composites.The economy together with greenness were the key factors affecting the development of advanced composites.Future studies needed to focus on a further fundamental study towards the mechanism of the interfacial interactions between lignin and polymer,develop advanced composites via adjusting the microstructure and aggregation performance of lignin,as well as broaden the valorization of industrial lignin in smart materials,medical materials and others.This review proposed a systematic summary and induction of the design and construction of lignin/polymer composite,which proposed the theoretical basis and research ideas towards the advanced materials development and application in this field.关键词
