Abstract

Lignocellulosic fibers have been received an intense attention to many researchers due to their tremendous advantages.Today,the lignocellulosic fibers have been value added through many ways such as handicraft,textile industry and so on.The aim of this study is to prepare nanocellulose in term of cellulose nanocrystals that derived from banana trunk fiber by using 40 wt% sulphuric acids (H2SO4) via acid hydrolysis method.Despite of this, the effect of hydrolysis time and temperature correlation is studied in order to find the optimum conditions of cellulose nanocrystals of banana trunk fibers which are possessed high crystallinity in their crystal structure by using acid hydrolysis method.The elemental chemical composition for different chemical stages is determined by using Fourier Transform Infrared (FTIR) while the crystallinity index and crystallite size is determined and evaluated by using X-ray diffraction spectrometer (XRD).The effectiveness of the alkali treatment of 6 wt% NaOH is evaluated through the surface morphology by using Scanning Electron Microcopy (SEM).Thus,the cellulose nanocrystals has been successfully produced with the optimum condition at 90 ˚C for 30 minutes by the 31.73 % crystallinity index by 5.47 nm of the crystallite which act as a sustainable source due to the cheap,eco-friendly and its avaibility while preventing pollution to the environment that caused by banana trunk wastes.
