Abstract
The present invention provides a phase change material composition comprising an ester of a linear alcohol which has at least 4 carbon atoms and a linear carboxylic acid which has at least 4 carbon atoms, wherein the total number of carbon atoms in the ester is in the range from 13 to 31. The invention also provides products including the phase change material composition and methods of regulating temperature.
Claims21
A method of regulating temperature in an environment comprising the steps of:
- providing in the environment an amount of a phase change material composition comprising an ester of a linear alcohol which has at least 4 carbon atoms and a linear carboxylic acid which has 7 or 9 carbon atoms, wherein the total number of carbon atoms in the ester is in the range from 13 to 31;
- and
- storing or releasing thermal energy in the phase change material composition by transfer of thermal energy between the environment and the phase change material composition, such that the temperature of the environment is regulated over a period of time.
