报告内容简介
Lignocellulose based nanomaterials such as cellulose nanocrystals (CNC) have attracted great interest recently due to renewability, biodegradability, and other unique mechanical and optical properties with a potential to produce a variety of products for a sustainable future. Achieving economic and environmentally sustainable production, however, is the key to commercial success.
In this presentation, I will outline the current status of cellulose nanomaterial production including the deficiencies of existing technologies. Then, I would like to discuss some of our research on integrated production of cellulose nanocrystals (CNC) and fibrils (CNF) with full recovery of chemicals. Specifically I will present our recent study using dicarboxylic acids (DCAs) for sustainable and potentially economical production of highly thermal stable and functional (carboxylated) cellulose nanomaterials. Finally, I will briefly discuss our progress in producing lignin containing cellulose nanomaterials and lignin nanoparticles (LNP). Specifically, I will present a low temperature ( ≤ 80 °C) and low energy wood fractionation process for producing lignin CNF (LCNF) and LNP, rather than from chemical pulps, to substantially reduce production cost.
