Synthesis and Characterization of Zn-Al, Mg-Al Layered Double Hydroxides Intercalated Polymer Nanocomposites

Abstract

Layered double hydroxides (LDHs) also known as hydrotalcite-like materials, provide the opportunity of preparing new organically modified 2D multifunctional nanocomposite materials. In present work, the embodiment consists of the synthesis and characterization of two different LDHs namely Mg-Al, Zn-Al hydrotalcites and their conducting polymer nanocomposites comprises of polyaniline (PANI) into each of the LDHs to get an overall of four different LDH-conducting polymer nanocomposites and are characterized by FT-IR, powder XRD, SEM and BET surface area measurements. The spectral characterization showed interesting results on the formation of wonderful nanocomposites. Hence, it is postulated that due to their cationic/ anionic exchange behaviour, these materials shall find futuristic applications viz., ion selective electrodes, sensors, ion exchange resins, water purifications, optoelectronics, solar cell applications etc. Due to their diverse ion-exchange capacity and their sub micron size particle distribution with good cohesive properties, it is suggested towards possible drug delivery applications.
