Preparation of Chitosan-Cellulose Composite Beads Using Cellulose Isolated From Sugarcane Bagasse

Abstract

Chitosan-cellulose composite beads had been prepared using cellulose isolated from sugarcane bagasse. Sugarcane bagasse was hydrolyzed with H2SO4 with various concentrations (30, 40, and 50%). Cellulose obtained was characterized using Fourier Transform Infrared (FTIR), X-Ray Diffraction (XRD) and Scanning Electron Microscope (SEM). FTIR analysis results inform the existence of typical functional groups of cellulose in the sample. XRD patterns show H2SO4 concentration on the hydrolysis process influence the crystallinity of cellulose. Cellulose was used as a filler in the preparation of chitosan-cellulose composite beads. The results show that cellulose decrease the crystallinity of chitosan.

Fabrication of Glycidyl Methacrylate (GMA) Grafted Cellulose from Rice Straw

“…Physically, cellulose is a fibrous, hard, water-insoluble material which plays an important role in maintaining the composition of plant cell walls [2]. Cellulose can be easily obtained from various types of plants, such as from rice straw [4][2] [5], jute [6], sugar cane bagasse [7], corn cobs [8], bamboo [9], empty palm oil bunches [10] and others. Cellulose can be used as an alternative material, such as making bioplastics, IOP Publishing doi:10.1088/1755-1315/1297/1/012042 2 adsorbents, and fillers as reinforcements in making polymer composites.…”
