Cellulose is one of the most abundant and ubiquitous polymers on the planet Earth occurring in wood, cotton, hemp and other plant-based materials and serving as the dominant reinforcing agent in different matrices. Nano-scale celluloses like cellulose nano-fibrils, nano-whiskers, microfibril-lated cellulose, and bacterial cellulose are high-value materials that serve as promising candidates for bio-nanocomposite production. Nano-scale cellulose has different attractive properties like high strength and stiffness, low weight and biodegradability. In the present study, nano-cellulose was prepared from five different sources by mechanical method which was used by SUPERMASSCOLLOIDER(MASUKO SANGYO, Japan) and high pressure homogenizer(SPX, USA). The effect of mechanical method on the properties such as particle size, aspect ratio and yield of nano-cellulose have been investigated. |
