The tensile testing provides an indication of the strength. Drug Release Kinetics Drug release kinetics was analyzed by plotting the cu- mulative release data vs. In the present study, the presence of carboxylic dimmer was due to the acetic acid used for dissolving the chitosan [6].

Blending leads to an intermolecular interac. Introduction Carrier-mediated drug delivery has emerged as a power- ful methodology for the treatment of various pathologies. Due to possibility of interaction between -OH and -NH 2 groups cloisiet these two polymers, blending improves mechanical properties of the films. Cross-linking with glutaraldehyde improves tensile strength and decreases tensile strain of the blend films. MMT is also a potent detoxifier, which belongs to.

The imine group was formed by the nucleophilic. Further the electrostatic interaction of composites is more easily broken at pH 7. The effect of glutaraldehyde to improve tensile strength increases by increasing Cs con- tent in the blend films. An- other broad peak at cm —1 is caused by amine N-H symmetrical vibration, which is used with cm -1 for quantitative analysis of deacetylation of chitosan.


Water absorption was calculated as a. S2 GA 1 Cu- mulative release data presented in Figure 6 indicate that by increasing the pH from 1.

A New Versatile Biopolymer for Va. Figure 1A — a spectrum of pure chitosan shows peaks around and cm —1 corresponding to saccharide structure [19]. Hence, there is a significant reduction of intensities. The cross-linking of chitosan and PVA with glutaraldehyde is shown in Figure 3. Applied Polymer ScienceVol. This suggests that the drugs in the composites can. Part BPolymer Phys- icsVol. The amount of curcu. The plausible mechanism of drug deli- very has been postulated based on the kinetic data.

The h ydrophilicity of the polymer due to 03b functionality in most repeat units makes the polymer soluble in dilute acid [10].

This was driven by the realization that. Poly vinyl alcoholPVA, is a non-toxic, water-solu- ble synthetic polymer and has good physical and chemi- cal properties and film-forming ability [4]. Tensile strength and tensile strain -at-break for different samples.

This compound was used 30 drug delivery purposes. Data sheets for overmetals, plastics, ceramics, and composites. There are two distinct peaks at and – cm —1. Peaks at and cm —1 are the typical C-H stretch vibra- tions [5]. The h ydrophilicity of the. The success of synthetic polymers as biomaterial relies mainly on their wide range of mechanical properties, transformation processes that allow a variety of closiite shapes to be easily obtained and low production costs [2].
