Patent application: Manufacturing a composite PCM for clothing

Ben Welter - Friday, July 17, 2015

U.S. patent application 20150197678 (assignee Honeywell International Inc.):

"Composite phase change materials, methods for manufacturing composite phase change materials, and articles of clothing including composite phase change materials for temperature regulation are provided. In one example, a composite phase change material includes a cross-linked polyethylene glycol matrix and a phase change material filler. Each of the cross-linked polyethylene glycol matrix and the phase change material filler has a phase change temperature of from about 10 to about 60° C. Further, the composite phase change material has a latent heat of enthalpy greater than about 50 kJ/kg."
