Experimental study on effective thermal conductivity of microcapsules based phase change composites

A sort of new microcapsules based phase change composites (PCC) with carbon network to enhance the thermal conductivity and thermal stability was developed. An effective modified model was presented based on the thermal conductivity of PCC with different mass fraction of EG. Verified by the measured data, the average error of the modified model is successfully limited within ±9.6%. This indicating the theoretical model proposed in this study can be generalized to predict the thermal conductivity of such kind of composites.
