Abstract
Methods of making a thermoset thermal energy gels, such as one having a radiation cured polymeric network, are disclosed. The methods include providing a hydrophobic PCM in its liquid state, adding a polybutadiene urethane acrylate oligomer and a mono-functional or di-functional crosslinker soluble in the hydrophobic PCM to the hydrophobic PCM while maintaining the liquid state of the hydrophobic phase change material to form a liquid homogenous mixture, then adding a photoinitiator, which is soluble in the hydrophobic PCM, with mixing to form a final mixture. Next, curing the final mixture occurs by exposure to radiation to form the thermoset thermal energy gel.

A method of making a thermoset thermal energy gel, the method comprising:
- providing a hydrophobic phase change material in its liquid state;
- adding a mono-functional or di-functional crosslinker and a radiation curable resin thereto while maintaining the liquid state of the hydrophobic phase change material to form a liquid homogenous mixture;
- adding a photoinitiator to the liquid homogenous mixture with stirring to form a final mixture, the photoinitiator being soluble in the hydrophobic phase change material;
- curing the final mixture by exposure to radiation, thereby forming a thermoset thermal energy gel.
