摘要

Innovations in bio-based composites with improved performance are being driven by the growing need for premium natural cellulosic materials. The thermal, physical, chemical, and morphological properties of micro-sized cellulose fillers taken from Jatropha curcas leaves were observed in this study. Its biodegradability, low density, remarkable mechanical characteristics, thermal endurance, and compatibility with living beings make cellulose unique. The acid-hydrolysis process was used to extract cellulose from dried Jatropha curcas leaves. By the XRD analysis, it is reported that the purified microcrystalline cellulose attained a crystalline size of 12.63 nm and a crystallinity index of 72.54%. The structure of the extracted cellulose filler was studied using a scanning electron microscope and the ImageJ tool. The microfiller was found to have an average size of 94.63 μm. By employing Fourier transform infrared spectroscopy, the molecular bonds of cellulose can be studied. Cellulose had a surface roughness of about 66 nm, according to the AFM study. The processing temperatures of this material can reach 226.62 °C, and it contains particles that are micro-sized. Thus, from the various analysis and its results, cellulosic material produced from agricultural waste can be advantageous in polymeric composites, as demonstrated in the study. According to the research, cellulose from Jatropha curcas leaves could be used instead of common materials like microcellulose, microadditives, and additive manufacturing reinforcing agents.
