Abstract

The present study investigates the structural, crystallinity index, crystallite size, morphological, and the dimension of Nanocrystalline Cellulose (NCC) extracted from ramie fiber by hydrochloric acid-hydrolysis. NCC was chosen because it has high strength and modulus compared to other natural materials. Ramie fiber was chosen because it has high cellulose content and abundant in Indonesia. The other reason is ramie has a high crystallinity index compared to other natural fibers. The extraction process was carried out into two steps: cellulose purification then followed by hydrochloric acid hydrolysis. The characterizations of extracted NCCs were conducted through Fourier-Transform Infrared spectroscopy (FTIR), X-ray diffraction (XRD), Transmission Electron Microscopy (TEM), and Particle Size Analyzer (PSA). The focus of this research was to study the effect of acid concentration on the characteristics of extracted NCCs. The results show that NCCs could be extracted through hydrolysis using hydrochloric acid. Morphological analysis by TEM shows the formation of rod-like shaped NCCs. Hydrolysis by hydrochloric acid does not affect the chemical compound of cellulose. It was found that during hydrolysis, the higher acid concentration being employed had resulted in smaller dimension of NCCs and decreasing crystallinity index. © 2020 Trans Tech Publications Ltd, Switzerland.
