The deformation of cellulose nanocrystals can in fact be extended through surface hydroxyl groups that have the potential to confer desired functions. Our one-pot, multi-reaction synthesis route consists of grafting pyridinium salt and hydrogen bond breakage of cellulose. This reaction leads to nanoization and functionalization of cellulose concomitantly. The surface substitution ratio of the pyridinium salt on the resulting cellulose nanocrystals was demonstrated through XPS, zeta potential, and dye adsorption analysis. Cationic cellulose nanocrystals could further open other innovative applications such as; gene and drug delivery, Bio-flocculants and additives. This simple process uses very little organic solvent, and the ionic liquid is reusable. Hence, it is expected to be used as a meaningful reaction path which is both economical, and environmentally friendly. |
