Abstract Hexadecanoicacid (HA) was selected as the substrate and expanded graphite (EG) was adopted as the supporting material of high thermal conductivity. High form-stable precision HA/EG composite phase change materials (PCMs) were fabricated by the improved method of melting blend-solidification and form-stability. Thermal properties of form-stable PCMs samples with different parameters were systematically measured. The effects of microstructure, functional group distribution, crystalline phase, mass fraction of EG and sample density on the properties of form-stable PCMs were investigated by various instruments. The results showed that the blend of HA and EG were more uniformly and the combination degrees were enhanced with the increasing mass fraction and density of HA, which was absorbed into the porous structure of EG by physical interaction rather than chemical reaction. The melting enthalpy of pure HA and form-stable PCMs with the EG mass fraction and sample density of 30% and 900 kg/m³ were 275.35 kJ/kg and 193.01 kJ/kg, and the melting point of 59.53 ℃ and 61.08 ℃, respectively. The horizontal thermal conductivity of the latter was as high as 38.42 W/(m·K), which was about 236 times higher than that of pure HA (0.162 W/(m·K)). The vertical thermal conductivity of the latter was 2.68 W/(m·K), which was less than one-fourteenth of the horizontal, which showed high anisotropy. The cyclic stability test results of all the samples suggested that the EG mass fraction of 24% and 30% with samples had a slight leakage, which were lower than 0.85% and exhibited the wonderful cycle stability. HA/EG form-stable PCM was a kind of latent heat storage material with excellent performance, which had a broad application prospect in solar thermal utilization.
