| Abstract: | The positive temperature coefficient (PTC) phenomena and mechanism in polymer based PTC materials are reviewed from the point of view of materials design. Various influential factors on PTC effect such as polymer matrix, conductive particles, filler pretreatment and dispersion, as well as the methods for stabilizing PTC property,are discussed. Furthermore, the trends of development of PTC material are also previewed. |
