PURPOSE:To obtain a small-sized composite heat storage article with controlled agglomeration of the heat storage material due to repeated heat cycles, by using a conductive polymeric material and a latent-heat storage material. CONSTITUTION:A polymeric material comprising rubber (e.g., ethylene/propylene rubber) or resin (e.g., PE), and conductive particles comprising metal or carbon black particles are dissolved or dispersed in a solvent, to which a latent-heat storage material (e.g., a powder of CH3COONa.1OH2O-NaHPO3 heat storage material) having a latent heat of 30-90cal/g is added to form a dispersion. This dispersion in poured into a flat-panel mold and the solvent is allowed to evaporate, thus giving a composite heat storage article in sheet form. |
