Аннотация

Due to recent development of hand-held mobile devices and flexible display technology, large demand for high thermal conductivity plastics is present. As a result, polymer composites having comparable thermal conductivity to stainless steel at room temperature are commercially available nowadays. Usually, metal or carbon fiber or particles are added to base polymers to enhance the thermal properties. However for polymer composites having high filler concentration, problems such as anisotropic thermal conductivity and nonhomogeneity of the material due to filler alignment and aggregation are present. In this paper, a thermal property measurement method based on the 3-omega (3ω) is proposed for thermal analysis of polymer composites with spatial resolution below 0.3 mm. Preliminary thermal conductivity measurement result of a commercial polymer composite shows that the present method can be applicable to analyze the localized filler distribution with in a polymer composite sample.
