Abstract

A thermochromic polymer composition including a base polymer material; a temperature sensitive material, which changes a color of the thermochromic polymer composition in response to a temperature change; and a stabilizer, which enhances stability performance of the thermochromic polymer composition. The thermochromic polymer composition which has a good thermochromic performance and good thermal performance and thus could provide a visible indication of the overheat condition. An electrical device is formed from the thermochromic polymer composition. A further embodiment of the process for preparing the thermochromic polymer composition and forming the electrical device.
