Preparation of Chitosan-Grafted Nanocellulose via Microwave-Initiate Method

摘要

Chitosan and cellulose are one of natural flocculants. Natural flocculants are non-toxic and biodegradable. Chitosan was grafted onto nanocellulose from empty fruit bunch (EFB) polymer by a irradiation from microwave initiated method. Effects of ratio chitosan to nanocellulose (0.2:1, 0.4:1, 0.6:1, 0.8:1 and 1:1) and irradiation time (1min, 2min, 3min, and 4min) on grafting were studied. Grafting was confirmed through weigh analysis and element analysis. The synthesis method was found to be both efficient and selective for grafting. Novelty, both of the natural polymers was successfully grafted. The grafting percentage was high for ratio cellulose to chitosan 1:1 with 56% at 2min reaction time.
