Abstract Scope |
There is an increasing demand for green and natural materials in the design of advanced composites. Nanocellulose is an abundant natural nanocrystal that has been studied extensively for its reinforcement effects in polymer matrix composites. In this study, the adhesion reinforcement effect of nanocellulose at glass fiber and epoxy interphase is investigated using the molecular dynamics simulation method. The chemical and physical bonds, including hydrogen bonds, are calculated when a nanocellulose is added to hydroxylated and silane-coated SiO2 surfaces. The cross-link site density of epoxy is studied in the presence of nanocellulose and silane. The adhesion property and glass transition temperature of the glass fiber/epoxy interphase models are correlated to the bonding structure at the interphase. The results of molecular dynamics simulation support the experimentally observed enhancement effects of nanocellulose and provide atomic evidence in further exploring the application of nanocellulose in polymer matrix composite. |
