Ionic Liquid Microemullsions, Templates for Directing Morphology of Cellulose Biopolymer Nanoparticles (Briefing Charts).

摘要

Cellulose is the most abundant natural polymer on Earth. Cellulose is intra and inter-molecularly connected by hydrogen bonds, and is insoluble in water and most organic solvents. Ionic Liquids (ILs) form electron donor-acceptor complexes with hydroxyl groups of cellulose resulting in separation and dissolution. Microemulsions are transparent, isotropic, and thermodynamically stable dispersions of two immiscible liquids stabilized by surfactant. Recently, ILs have replaced water and/or traditional organic solvents to prepare novel IL-based microemulsions.
