Abstract

In this paper, we present the study of preparation and ionic conductance for an intercalated hybrid of kaolinite with potassium dihydrogen. The intercalation efficiency is high up to ca. 90%. The intercalated hybrid has been characterized by powder X-ray diffraction, infrared spectroscopy, and thermogravimetric analysis. The ionic conductivity (σ) of the hybrid material is strongly dependent on the moisture in the environment, with σ = 8.4 × 10⁻¹⁰ S cm⁻¹ at 293 K and gradually increases to 7.16 × 10⁻⁹ S cm⁻¹ under N₂ atmosphere (anhydrous environment) at 353 K as well as an activation energy of E_a = 0.618 e V, whereas σ = 2.19 × 10⁻⁴ S cm⁻¹ at 100% relative humidity and 293 K with E_a = 0.44 eV. The mechanism that the moisture affects the ionic conductance of the intercalated hybrid is further discussed.
