Cellulose nanofiber (CNF) extracted from the wood are eco-friendly and have excellent properties, so interest in CNF-reinforced polymer nanocomposite is increasing. However, there is a problem that it is difficult to prepare the composite due to the low dispersibility and limited thermal resistance of CNF during high-temperature melt-mixing processes. This problem can be solved by generating inorganic nanoparticles on the CNF surface through a sol-gel process. In this study, the nanoparticle morphology was controlled by controlling wetting properties on the surface so that the surface of CNF could be sufficiently protected even with lower silica content. As a result, it is expected that CNF with reduced silica content and improved dispersion and thermal resistance can be obtained. Mechanical and rheological properties of the composite also were analysed. |
