“…With a higher irradiation of 25 kGy, further lowering of the peak intensities was likely to relate to further changes in the structure. This result was consistent with that of reported in [25] that utilized chitosan/starch films irradiated with gamma-ray.…”

Abstract. The effect of different gamma-ray irradiations on the functional groups and the mechanical properties of chitosan, collagen, and chitosan/collagen blend have been studied. Commercially available chitosan and extract of collagen from bovine tendon by acid dissolution method were employed. Chitosan, collagen and chitosan/collagen blend membranes were prepared using the solvent evaporation method. The dried membranes were subjected to gamma-ray irradiation using 0, 15, and 25 kGy. The membranes then characterized by Infrared spectroscopy and measured in tensile and elongation at break. The irradiated chitosan membranes displayed reduced intensity of -OH, -CH, -NH and -C-O-C groups, whereas, the collagen membranes revealed amide I, II and III groups. The irradiated chitosan/collagen (50/50%) blend membranes demonstrated the decreased intensities in the -OH and amide groups. The application of gamma-ray irradiation had produced chitosan/collagen blend membranes with a tensile strength and elongation at break between the chitosan and collagen membranes. It was further determined that the decrease in the mechanical properties of the membranes was likely to be due to some changes of the functional groups.

This work focuses on polymer electrolytes composed of a starch-chitosan blend host, ammonium iodide (NH 4 I) and glycerol. Fourier transform infrared (FTIR) analysis confirms the interaction of starch-chitosan-NH 4 I-glycerol. The highest room temperature conductivity is (1.28 ± 0.07) × 10 −3 S cm −1 , obtained by a sample containing 30 wt% glycerol. Dielectric studies showed that the electrolytes obeyed non-Debye behavior. The total ionic transference number for the 30 wt% glycerol sample was 0.991, and the conduction mechanism for this sample followed the quantum mechanical tunneling (QMT) model. Linear sweep voltammetry (LSV) showed that this sample was electrochemically stable up to 1.90 V. The highest conducting sample was used in the fabrication of an electrical double layer capacitor (EDLC) cell.

“…Among biopolymers, chitosan has been considered as one of the most promising materials for future applications on account of its excellent biocompatibility, biodegradability, anti-microbial activity, non-toxicity, and its economic advantages (Rutnakornpituk et al 2006;Singh et al 2009). Besides, when placed into a solution of relatively low pH, chitosan can be dissolved as a cationic polyelectrolyte (Tuhin et al 2012). Chitosan is readily soluble in dilute acidic solutions below pH 6.0 and can therefore be considered a weak base.…”

“…Through reaction with a cross-linking agent, chitosan may obtain hydrogel-like properties, which allows it to be used in a wide range of applications such as food packaging, wastewater treatment, and drug delivery systems (Thanpitcha et al 2006;Tuhin et al 2012). There have been numerous studies on chitosan, such as chitosan blended with natural polymer (Garcia et al 2006;Senna et al 2012;Zhai et al 2004), synthetic polymer (Salmah and Azieyanti 2011;Salmah et al , 2012a, and modified chitosan (Ambri et al 2013;Beppu et al 2007;Rutnakornpituk et al 2006).…”

Chitosan/Corn Cob Biocomposite Films by Cross-linking with Glutaraldehyde

2013

Corn cob (CC) was used as a filler in chitosan (CS) biopolymer films. The effect of glutaraldehyde (GLA) as a crosslinking agent was studied in an effort to improve the properties of CS/CC biocomposite films prepared via solvent casting. The tensile strength and elongation at break values decreased, but the modulus of elasticity increased with CC content. However, the tensile properties of CS/CC biocomposite films improved when modified with GLA. The Fourier transform infrared (FTIR) results indicated the presence of imine bonds (C=N) and ethylenic groups due to the cross-linking reaction between CS and GLA. The thermal stability of CS/CC biocomposite films reduced with increasing CC content. The modification of CS/CC with GLA enhanced the thermal stability of the biocomposite films. Moreover, the wettability and adhesion of the CC-CS system were enhanced by modification with GLA, as demonstrated by a morphological study. The crosslinking agent glutaraldehyde positively affected the tensile strength, modulus of elasticity, and thermal stability of the biocomposite films.
