In the field of materials science, polymers can be regarded as the key to developing advanced components for a wide category of devices. In most situations, adding additives or fillers can enhance the performance of macromolecular compounds. Depending on specific features (size, shape, functionality) and the amount of the incorporated substance in the polymers, the composite properties can be tailored. The principal objective of this study was to propose some new multiphase polymer composites and to evaluate their transport properties. The samples were projected by using a conjugated polymer, which is combined with a mixture of two sorts of fillers. The chosen reinforcement agents were a mix of silver particles and carbon nanotubes that were either completely clean or had different functional groups attached to them (-OH, -COOH, -NH2). Molecular modeling of the newly designed systems was undertaken to determine certain important physical parameters, such as polarizability, partition coefficient, and refractivity. Furthermore, the samples were analyzed from the point of view of their electrical and thermal transport behavior. For assessing the electrical conductivity, the parallel and Lichtenecker models were used as mixing rules for composites. Then, thermal conductivity was estimated by using the Wiedemann-Franz law. The results were discussed in agreement with the sample’s composition and potential utilization in microelectronics.
