Investigation of Moisture Sorption Properties of Gelatin/Poly (Aniline)/Films

Abstract

This work describes moisture sorption behavior and other physico-chemical properties of gelatin/poly (Ani) films. Theglyoxal (Glox) -cross linked gelatin (Gel) films have been loaded with aniline, followed by their in-situ oxidative polymerization to yield Gel/poly (Ani) composite films. The moisture uptake behavior of the plain Gel and Gel/poly (Ani) films has been studied under various Relative Humidity (RH) and at different temperatures. The data obtained has been interpreted in the terms of GAB model. The thermodynamic parameters such as q st and sd have also been determined using Clasius-Clapeyron equation. It was found that both, the qst and the sd decreased with moisture contents. Finally, the films exhibited fair biocompatible behavior.
