•Al/Al2O3 micro-encapsulated phase change materials (MEPCMs) were prepared by adding different amount of Al(OH)3.•TEM observation was conducted that θ-Al2O3 is formed on the surface of the MEPCMs, which is conductive to the durability.•At the condition of 2 g/L Al(OH)3 addition, the MEPCM can presen...
