Polyethylene composites containing a phase change material having a C14 straight chain hydrocarbon
First Claim
1. A composite useful in thermal energy storage, said composite being formed of a polyethylene matrix containing at least about 10% by weight of a straight chain alkyl hydrocarbon phase change material having at least 14 carbon atoms incorporated therein, said polyethylene being crosslinked to such a degree that said polyethylene matrix is capable of absorbing at least 10% by weight of said straight chain alkyl hydrocarbon phase change material.
