POLYMERIC ENERGY STORAGE MATERIALS

摘要

Compositions, coatings, and energy storage fabrications made of support polymers or active waxes in a grafted matrix to an amorphous wax and at least one functional compound and their methods of preparation are presented. Amorphous waxes are typified by paraffin waxes. Functional compounds include various fatty alcohols, fatty acids, ester, amines, and amidoalkylamines. Sulfonated and oxidized ion exchange resins may be grafted to the matrix. The compositions are capable of storing or releasing energy upon a physical phase change transition.

主权项

1. A composition comprising at least one support polymer grafted to at least one amorphous wax and further grafted to at least one functional compound having a phase change active group, wherein the composition is a modified wax capable of storing or releasing energy upon a physical phase change transition, wherein about 1% to about 70% by weight of the at least one amorphous wax is covalently bound therein, and about 1% to about 70% by weight of the at least one functional compound is covalently bound therein.
