研究方向
主要研究領域集中於以木質纖維可再生生物質(lignocellulosic biomass)為原料的產品的開發和利用。在過去幾年中所進行的研究項目包括,1)以木材液化技術為基礎的生物煉製方法的研究。該方法以木材液化為核心技術,分離木質纖維生物質中的三大組份(木質素、半纖維素和纖維素),並且以分離的各組份為原料生產可降解生物基隔熱材料及其它功能材料;2)通過去甲基化來提高木質素的活性,並以去甲基化的木質素替代部分苯酚用以生產酚醛樹脂;3)以木材液化為核心技術回收處理CCA防腐木材,並利用除去重金屬後的液化木材來生產可降解生物基隔熱材料;4)對非食用植物油脂的改性研究,並以改性後的油脂為原料生產聚氨酯材料 。
