概要

論文の詳細を見る
Porous materials of AlOOH-Al_2O_3 were prepared by precipitation of aluminium chloride solution using aqueous ammonia, and by heating at various temperatures below 400℃. The obtained porous materials showed steep increase of water vapor adsorption in the relative humidity range of 55-90%. This porous material is, thus, considered to be a candidate for intelligent humidity control materials (Humidity Self-controlled materials). Pores formed by sublimation of coexisting ammonium chloride in the sample contribute to the improvement of the humidity conditioning property.
