Summary Myristyl alcohol (MA)/polyvinyl butyral (PVB) composites with carbon nanotubes (CNTs) as composite phase change materials (CPCM) were synthesized by the solution blending method. MA was selected as phase change material (PCM) due to high latent heat. PVB was utilized as matrix to decrease leak of MA in molten state. CNTs were added into CPCM as thermal conductivity enhancer, which behave high thermal conductivity. A series of samples were prepared. The chemical and crystal structures of CPCM were analyzed by Fourier transform infrared spectroscopy and X‐ray diffractometer. The results showed that there was only physical adsorption and no chemical reaction during mixing process. The microstructure of CPCM was observed by scanning electron microscope. Differential scanning calorimetry, thermogravimetric analysis, and thermal conductivity meter were used to measure thermal properties of CPCM. The results indicated that S2 containing 80 wt% MA had latent heat value of 150.55 kJ/kg, the corresponding melting temperature was 52.03°C. CPCM has no thermal decomposition in the operating temperature range, so they have excellent stability. In addition, the thermal conductivity of S5 containing 6 wt% CNTs is 1.062 W/(m·K), which is increased by 4.65 times compared to that of S2. The melting latent heat of S5 is 147.50 kJ/kg, which is 97.97% of S2 melting latent heat.
