J043013 Thermal Conductivity and Processability of Polymer Composites with Nano and Micro Fillers

Abstract

Thermal conductivity and processability of polymer composites with nano and micro fillers have been investigated. The nano fillers used were carbon nanofibers (CNFs), and the spherical alumina particles and the carbon fibers were selected as the micro fillers. Packing simulations were performed to obtain the random close-packed structure of two filler systems (i.e. two-particle, large-particle/small-fiber, large-fiber/small-particle and two-fiber). In addition, experimental measurements of the thermal conductivity and the viscosity of the manufactured polymer composites with CNFs and the close-packed structure of micro fillers were carried out. The microstructure of the polymer composites was also examined using a scanning electron microscope.
