According to the declaration of carbon neutrality, the industry is conducting research on the reinforcement and weight reduction using eco-friendly textile materials. Currently, when manufacturing CNF-polymer composites, powdered CNF is supposed to use for high temperature melt mixing processes. However, when CNF is dried, a strong capillary force acts between the nanofibers to cause agglomeration. In this study, in order to reduce the agglomeration, gel form of CNF where CNF is well-dispersed is used for the melt-mixing process. For better dispersion and reducing thermal oxidation, CNF was mineralized on the surface weakening van der Waals interactions between them. Mechanical and rheological propertied of the composite were analyzed. |
