Abstract

A new type of thermally conductive fibers based on silver coated wollastonite was prepared and characterized. The fibers were used for the preparation of elastic, highly thermally conductive polymeric composites based on ethylene-vinylacetate copolymer (EVA). It was shown that silver coated fibers significantly improved the thermal conductivity of composites despite the low silver volume content. The experimental results were discussed and compared to various theoretical models. The specific heat and the specific density of the composites were also characterized and reported.
