摘要

Bio-based composites were widely considered as a replacement for various synthetic fiber-based composites due to their availability and their environmentally friendly, biodegradable, and sustainable properties. In this study, microcrystalline cellulose was prepared from Pandanus fascicularis Lam fibers through bleaching and ultrasound assisted acid hydrolysis using sodium hypochlorite and sulphuric acid. The obtained Pandanus fascicularis Lam fiber microcrystalline cellulose was characterized by morphology, thermal and chemical analysis. The density and chemical composition of the obtained microcrystalline cellulose was also identified by suitable methods. The methodology effectively yielded Pandanus fascicularis Lam fiber microcrystalline celluloses with a mean dimension of 471.6 nm and a crystallinity index of 70.2%. Furthermore, thermal analysis techniques verified the microcrystalline cellulose’s thermal stability up to 272 °C. Functional groups in Pandanus fascicularis Lam fiber microcrystalline cellulose was identified using Fourier transform infrared spectroscopy. The assessment of microcrystalline cellulose’s properties and surface morphology by Scanning electron microscopy, Transmission electron microscopy and Atomic force microscopy substantiates the utilization of microcrystalline cellulose as a reinforcing agent in bio composites for lightweight structural applications. The novelty of this work lies in transforming an unexploited coastal biowaste into functional microcrystalline cellulose, thereby contributing to sustainable material development.
