Features: This book analyzes and studies the functional principles of composite conductive polymer materials using concepts from materials science, such as connectivity graphs, additivity, multiplicativity, and coupling. It particularly focuses on the positive and negative temperature coefficient (PTC, NTC) resistance behavior of this composite material near its conductive percolation threshold, electrical switching characteristics, self-heating electrocaloric behavior, sensing functions, and the coupling relationships between these responses and different external field excitations. Typical material systems include carbon black-filled high-density polyethylene, which has been widely used in industrial applications, but also appropriately involves other materials such as multiphase polymer matrices or carbon fiber fillers. Through modeling and deduction, readers can gain a deeper understanding of the intrinsic connections between the composition, volume fraction, and especially the microstructure of these materials and their conductive properties in composite materials, thereby laying a more general foundation for the design, preparation, and application of such materials. The majority of the data in this book comes from the author and their research team's recent work, but this does not mean these data or results are the best, highest, or most representative. The book only uses general formulations and common preparation methods to produce typical composite conductive polymer materials and devices, followed by analysis to identify the underlying common principles. The target audience of this book is primarily professional researchers in composite conductive polymer materials, but its fundamental theories and knowledge are fully applicable to undergraduate and graduate students in polymer materials and composite materials, helping to broaden their horizons.
