摘要：

Porous materials of AlOOH-Al2O3 were prepared by precipitation of aluminium chloride solution using aqueous ammonia, and by beating at various temperatures below 400degreesC. 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.
