利用资源丰富的木质素制备生物可降解材料或从木质素中获取高价值芳香类化合物,是高效制备生物基材料和非石油路线炼制关键平台化合物的重要途径。然而,木质素在材料领域应用还存在比较显著的界面相容性问题,在炼制平台化合物方面存在转化率和产物选择性较低的问题,从而制约了木质素的快速应用。针对以上问题,我校轻工科学与工程学院(柔性电子学院)李新平教授团队在木质素化学与材料方面开展了系列研究。
游翔宇副教授等利用溶剂交换法开发了一种木质素/聚(N,N-二甲基丙烯酰胺)和海藻酸钠/Ca2+的双交联网络木质素基水凝胶。得益于多层次的刚性网络和能量耗散结构,这种兼具高模量、超韧性和优异传感能力的木质素基水凝胶,在极限运动保护和可穿戴传感器中显示出应用潜力。该研究发表于国际顶级期刊Advanced Functional Materials。
王文亮副教授等提出了一种微波响应型催化剂,并成功用于克量级木质素解聚蒸气的微波辅助催化重整,为从资源丰富的木质素中规模化获取关键的酚类和芳香烃类平台化合物提供了行之有效的途径。该研究发表于国际顶级期刊Applied Catalysis B: Environmental和Chemical Engineering Journal。
薛白亮教授等利用五/六元环碳酸酯反应特点,提出了具有动态交联结构的新型木质素基非异氰酸酯聚氨酯合成路线。基于星型木质素接枝共聚物的可控合成,利用核-核副反应与动态化学策略,构建了木质素基动态双网络结构,探究了其在胶黏剂和可降解塑料等领域的应用。该研究发表于Polymer Chemistry等国际期刊。
