The manufacture process influence on thermal conductivity of polymers thermal interface materials with carbon nanotubes

Abstract

In this paper the manufacture process influence on thermal conductivity of polymer composites used as the Thermal Interface Material (TIM) is presented. To evaluate the influence of the manufacture factors the design of the experiment technique (DoE) and Analysis Of Variance for the results (ANOVA) were used. From the experiment results one import5ant factor and one important interaction have been specified which have the most important influence on the experiment. The factor is the time of mixing of dispersed carbon nanotubes in the polymer matrix and the interaction is the interdependence between the content of carbon nanotubes in the composite and the way of mixing (piston and mortar or three roller-mill). To evaluate the results the thermal conductivity of the TIMs was taken.
