Ion Exchanged Zeolites for Electromagnetic Wave Absorption
Abstract
The overarching objective of this proposal is to investigate the potential of using ion exchange zeolites as electromagnetic absorbents, by studying the interaction and-or response of physicochemical properties and characteristics of various zeolite structures to the absorption, reflection, and transmission of waves (Figure 1). Our research studies will involve an integrated computational and experimental approach using primary zeolite structures and measuring their performance in a broad frequency range. Specifically, we will study the structures of Faujasite (FAU), Mordenite (MOR) Mordenite Framework Inverted (MFI), Linde Type A (LTA) zeolites. We will determine the effect of the zeolite structural characteristics (surface area, pore size, and pore distribution), water content and aluminum content in the pure zeolites on their dielectric properties. Based on the results we will select two promising zeolites and will study the effects of ions exchanged in the zeolite structure on the absorption, reflection and-or transmission of waves. Selected ions include Ni, Ce and Cu.
