Preparation for Spherical Humidity Control Composite Materials and their Humidity Control Properties

Abstract:

A spherical humidity control composite material with excellent humidity control performances has been prepared by twice foaming method. The composite comprises a natural polymer derivative (KGM), a porous natural mineral (Halloysite) and an Sodium polyacrylate (PAAS). It has high capacity for moisture adsorption, fast response to humidity changes, and small range for equilibrium humidity control. The moisture adsorption content of the composite material is 1.10 (g/g) of its own weight. The moisture absorption rate is 0.3948 (g/7h•g^-1), and moisture desorption rate is 0.4682 (g/7h•g^-1). The composite material has an equilibrium humidity control ranging from 50%RH to 53%RH. It can reach to the equilibrium levels within 60 minutes. It is suitable for maintaining a proper micro-environment for places such as museums or galleries.
