Cellulose is a natural polymer composed of long chains of glucose units that can be obtained from abundant biomass such as woods. Cellulose nanofiber (CNF) is produced by a rupturing process using cellulose such high-pressure homogenization. CNF is a renewable material and has many advantages such as biodegradability, biocompatibility, high mechanical strength and elastic modulus, and easy chemical modification. In recent years, studies have been performed to make polymer nanocomposites using CNF as a nanofiller for strength reinforcement. In order to maximize the physical properties of the nanocomposite, the nanofiller must be uniformly dispersed in the polymer. In this study, surface of CNF was modified with inorganic materials for improving dispersibility of CNF in polymer. Then, CNF-polymer nanocomposite was prepared by a melt-mixing process. Tensile strength and rheological properties of CNF-polymer nanocomposite in terms of CNF amount will be presented. |
