Preparation and Humidity Sensitive Property of LiCl/NaY Composite Materials

Abstract

Abstract: LiCl/NaY host-guest composite humidity-sensitive materials have been successfully prepared by dispersion of LiCl into the pores of zeolite. X-ray diffraction(XRD) and IRhave been used to investigate this system. LiCl/NaYmaterials can overcome the serious shortcomings of bulk LiCl, such as stability and durability at high humidity and at high temperature, contamination from dust or oil, etc. After a systematic investigation of LiCl/(NaY, ZSM-5, MOR), we have found that NaYis more suitable to be used as hosts, since NaYis characterized by a three-dimensional open framework structure, and composed of interconnected “super” cages.

Key words: Zoelite, Lithium chloride, Dispersion, Humidity sensors
