Metal-organic framework as a matrix for polyethylene glycol in thermal energy storage and preparations thereof

Abstract

The present disclosure is directed to a phase-change material (PCM) including a metal selected from cobalt and nickel and reacted units of 1,3,5-benzenetricarboxylic acid (BTC) for thermal energy storage and method of preparation thereof. The metal and the reacted units of the carboxylic acid form a metal-organic framework (MOF). The PCM further includes polyethylene glycol (PEG) present within a matrix of the MOF with a weight ratio of the metal organic framework to the polyethylene glycol from 10:1 to 1:10. The PCM of the present disclosure is in the form of agglomerated layers of wave-like sheets.

Dependencies are inferred from the claim text.
