摘要

The aim of this work is to determine the effect of coating and blending composition of myristic acid (MA) with polymethyl methacrylate (PMMA) on the latent heat and thermal stability of phase change material (PCM). Form-stable PCM (FSPCM) was prepared by blending MA with PMMA and then coating with nitrile butadiene rubber (NBR) and polyacrylic acid (PA) layers. This is the first attempt to coat the PCM with elastomeric latex. Leakage test results showed that addition of 20 wt% PMMA to the MA and NBR-PA coating layers could eliminate leakage in sample PCM8O. Tensile test results showed that NBR-PA coating material provide sufficient strength and elasticity to hold the PCM during the phase change process. Latent heat of melting and freezing of the form stable PCM80 is 107.56 J/g and 102.26 J/g, which is comparable with other results in the literature. (c) 2019 Wiley Periodicals, Inc. J. Appl. Polym.
