Electrically conductive multiphase polymer blend carbon-based composites



The present review focuses on summarizing key advances made on controlling polymer blend morphology to improve electrical conductivity in carbon-based polymer composite materials, including those based on carbon black, carbon nanotubes, and graphene. Fundamentals for controlling polymer morphology and the distribution of conductive fillers in various polymer composite systems and the impact on the electrical, rheological, mechanical, and thermal properties are reviewed. The concept of triple percolation and its beneficial effect on electrical conductivity is then reviewed. A high level overview of key theories and mechanisms related to phase morphology, percolation, and conductive properties in polymer composites is provided. POLYM. ENG.
