摘要

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.
