THERMOCHROMIC INDICATOR MATERIALS WITH CONTROLLED REVERSIBILITY
摘要
A thermal indicator material which comprises a plurality of polythiophenes having a second low temperature color and a high temperature color. The polythiophenes are structured and arranged to exhibit a color change from the second low temperature color to the high temperature color when the thermal indicator material is exposed to a temperature that meets or exceeds a pre-determined temperature and to exhibit a color change from the high temperature color to a first low temperature color when the thermal indicator material is exposed to a decline in temperature from a temperature that meets or exceeds the predetermined temperature to a temperature of within the range of between about 5 to 20 °C below the pre-determined temperature that occurs in a time period of greater than 2.0 seconds.
