Abstract
Nanocellulose has a great potential as a renewable material due to its high mechanical strength, high Young’s modulus, low density and eco-friendliness. Once a bulk material is made with it, then the bulk material made with nanocellulose can be a renewable bulk material, which is eco-friendly, lightweight and strong. Furthermore, it is known fact that cellulose has piezoelectricity due to its ordered domain of cellulose including crystal domains of cellulose. Thus, by aligning cellulose domains in the renewable bulk material made by nanocellulose, an eco-friendly and smart material can be developed. This paper aims at testing the feasibility of bulk material processing by using nanocellulose, specifically cellulose nanocrystal (CNC). The fabrication was carried out through steam with high temperature and high pressure to form hydrogen bonds between CNCs, followed by a heat and pressure molding. Its crystalline structure and physical interactions are investigated by using X-ray diffraction. Morphology and mechanical properties are investigated by scanning electron microscope and dynamic mechanical analysis.
