Abstract

The hybrid materials are mostly prepared by combining the organic or bio-organic part to the inorganic building blocks and are used in many applications. Gelatin as one of the main component of hybrid materials is an attractive option. It is biodegradable; biocompatible; non-toxic; bio-adhesive and contains many active groups such as –NH2, –COOH, in the biopolymer backbone makes these hybrid materials important in various technological applications. The synthesis of a series of gelatin-based nano-hybrid mesoporous materials was carried out using gelatin as the bio-polymeric backbone, silica, titania or zirconia; SDS as surfactant for o/w emulsion, TEOS as silylation or cross-linker material to obtain different hybrid materials for different applications. Hydrochloric acid (HCl) was used as catalyst, n-hexane as the solvent and sodium dodecyl-sulphate (SDS) as a surfactant for oil-water emulsification. Herein, sol‒gel technique was used to prepare the mesoporous Gelatin-EiO2 (Ei = Si/Ti/Zr) Based Mesoporous Nano-hybrids which are promising and efficient method. Thus, four kinds of different gelatin‒based hybrid materials: gelatin‒silica, modified gelatin‒silica, gelatin‒titania and gelatin‒zirconia based hybrid materials were synthesized. The effect of post-calcination on the properties of the as-synthesized hybrid materials was also studied and confirmed from various characterization techniques such as: elemental analysis, scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-Ray diffraction studies (XRD), thermo-gravimetric analysis (TGA), energy dispersive X-ray (EDX) and Fourier transform infrared (FTIR) spectroscopy and BET surface area analysis. To sum up, the materials synthesized are nano-hybrids which are mesoporous as confirmed from the various characterization techniques like SEM-EDS, have high surface area and are good candidates for many frontline applications.
