Effect of total solids content of nitrile rubber latex on coating performance of phase change material

Abstract

Phase change material (PCM) has attracted much interest in thermal energy storage (TES) applications due to its large heat storage capacity. The major drawback of PCM is the leakage of container, attributed by volume change during phase transition. Thus, the aim of this work is to produce form stable phase change material (FSPCM) with no leakage. FSPCM was prepared by encapsulation of myristic acid (MA) into the nitrile rubber (NBR) latex through dip coating. The performance of FSPCM was evaluated by using leakage test and the percentage of mass loss of MA after heating was calculated. PCM coated with 60% total solids content (TSC) of NBR latex shows no sign of leakage on the litmus paper. The percentage mass loss of FSPCM after thermal cyclic test was 0.46%. Thus, produced FSPCM has potential to be utilized in TES applications.
