Investigation of Moisture Sorption Properties of Gelatin/Poly (Aniline)/Films
نویسندگان
چکیده
This work describes moisture sorption behavior and other physicochemical 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 qst and sd have also been determined using ClasiusClapeyron equation. It was found that both, the qst and the sd decreased with moisture contents. Finally, the films exhibited fair biocompatible behavior.

Effects of drying temperature on barrier and mechanical properties of cold-water fish gelatin films
Fish gelatin films made from Alaska pollock (Theragra chalcogramma) and Alaska pink salmon (Oncorhynchus gorbuscha) were dried at 4 C, 23 C, 40 C, and 60 C. The tensile, thermal, thermal stability, water sorption, and water vapor permeability properties were examined for cold-cast gelatin films (dried below gelation temperature at 4 C) and hot-cast gelatin films (dried above gelation temperatur...

The effects of zinc oxide nanorod on the barrier, sorption isotherm and antibacterial properties of tapioca starch/bovine gelatin Bionanocomposite films were investigated. The nanorod-rich ZnO (ZnO-N) was homogenized by sonication and incorporated into tapioca starch/bovine gelatin solutions at different concentrations (e.g. 0.5, 2, and 3.5% w/w dried solid). Incorporation of 3.5% of nanopartic...

Fish gelatin and chitosan were used to develop composite biodegradable films using two strategies: (i) the mixture of both polymers to obtain homogeneous polymer matrixes and (ii) the formation of two layers. The films produced were characterized in terms of water absorption, solubility, water vapour permeability and mechanical properties. Both strategies revealed to produce films with a high s...
