Stability of hybrid inorganic-organic particles based on Poly(4-Vinylpyridine) adsorption on micron-sized mica platelets

A growing interest has been developed around the preparation of the organic-inorganic composites materials. because of their numerous technological and fundamental applications, many procedures of synthesis were described. they are based on physical and/or chemical interactions. thus, we synthesized for the first time two hybrid composite materials p4vp@mica containing mica, as mineral material and poly(4-vinylpyridine) [p4vp] polymer, with respectively ratios r=0.2 and r=0.5. these materials were characterized in previous article using, thermogravimetric analysis (tga), fourier transformed infrared (irtf) and scanning electron microscopy coupled with energy dispersive x-ray spectroscopy (sem-edx). in this article we study a stability of these materials by potentiometry and conductimetry
