A Review on Thermal Conductivity Enhancement of Organic Phase Change Material-Based Form-Stable Phase Change Materials

Fabrication of form‐stable phase change material with enhanced thermal performance based on the cocrystal of comb‐like polymer and paraffin

“…[4][5][6][7][8][9][10] Due to the high density of accumulated energy at constant temperature and narrow temperature region, the solid-liquid phase change materials (PCMs) are studied extensively and applied in TES recently. [11][12][13][14][15] Fatty acids, 16,17 fatty alcohol, 18 n-alkanes, 19 paraffin, 20,21 and polyethylene glycol (PEG) 2,22 are widely used as latent heat storage component of organic PCMs, and macrocapsulation or microcapsulation technology is often necessary to avoid the leakage in liquid state. [23][24][25][26][27][28] Unfortunately, the introduction of polymer supporting materials to obtain a form-stable phase change material (FSPCM) would affect the phase transition behaviors of PCMs, the decreased latent heats are often exhibited.…”

“…Thermal energy storage (TES) is one of the most perspective methods of improving the efficiency energy use and energy conservation, 1‐3 which have been applied in the field of waste heat recovery, central air‐conditioning systems, solar energy utilization, thermal‐regulated textiles, pharmaceutical field, and buildings and housing apartments 4‐10 . Due to the high density of accumulated energy at constant temperature and narrow temperature region, the solid‐liquid phase change materials (PCMs) are studied extensively and applied in TES recently 11‐15 . Fatty acids, 16,17 fatty alcohol, 18 n ‐alkanes, 19 paraffin, 20,21 and polyethylene glycol (PEG) 2,22 are widely used as latent heat storage component of organic PCMs, and macrocapsulation or microcapsulation technology is often necessary to avoid the leakage in liquid state 23‐28 .…”
