在植物纤维原料中,木质素是仅次于纤维素的天然可再生资源,但由于结构复杂且不同类型木质素结构性能差异,其通常被认为是一种废料或低价值副产品。微纳米木质素是近年来兴起的新发展方向,可为木质素产品高值化利用提供一种新途径。木质素微纳米球是一种具有规整结构的微纳米木质素,其自组装制备方法主要有溶剂-反溶剂法、气溶胶的流式反应器法和界面细乳液聚合法。利用四氢呋喃、二氧六环和乙醇等溶剂对木质素或化学修饰木质素进行溶解,然后滴加反溶剂去离子水可获得木质素微纳米球,然而溶剂-反溶剂法获得的木质素微纳米球悬浮液在干燥过程中存在微纳米球团聚问题;气溶胶的流式反应器法能将木质...

Lignin is the second most abundant plant biopolymer on earth after cellulose. However, lignin is not used extensively due to its complex structures. Lignin micro/nano-particles can provide many opportunities for value-added applications of lignin. Self-assembly method of lignin micro/nano-spheres, which possess regular structure, include solvent and anti-solvent method, aerosol flow reactor and interfacial miniemulsion polymerization.When lignin and its derivatives are dissolved in solvent, such as tetrahydrofuran, dioxane and ethanol, and then...
