The utilization of biofillers, such as cellulose, can improve the thermal and mechanical performance of thermoplastic composite materials and also modify the rheological properties of the polymer melts, leading to new requirements for processing equipment. One of the most noticeable changes in the utilization of biofillers is the much higher viscosity of the polymer melts and the equipment must be modified to process the high-viscosity materials. In this study, cellulose nanofibers (CNF) and pulp are used as biofillers that compounded with thermal plastics using a thermokinetic mixer. Our hypothesis is that the high shear force indued in high speed thermokinetic mixer can directly disperse wet CNF and pulp cakes into plastics with improved the dispersion of nanofibrils in comparison with dry compounding. Working with the injection molding, the rheological properties, processibility and mechanical performance of compounded composites are tested.
