1. Introduction
In all biomedical applications today, polymers are playing an important role. Many notable advances in technology have followed exploitation of the properties offered by new polymeric materials like blends and composites (Kittur et al., 2002; Muzzarelli and Muzzarelli, 2005; Qin et al., 2012; Chee, 1990; Sun et al., 1992). Biopolymers include the polysaccharides such as cellulose, starch, the carbohydrate polymers produced by bacteria and fungi and animal protein based biopolymers such as chitin, chitosan, wool, silk, gelatin and collagen; biopolymers, especially the carbohydrate origin, have been found to have a very promising industrial application in various forms (Singh, 2011). Most commercial polysaccharides (e.g., cellulose, dextran, pectin, alginic acid, agar–agar, agarose, starch, carrageenan, and heparin) are either neutral or acidic, but chitosan is a basic polysaccharide. In neutral or basic pH, chitosan contains free amino groups and is insoluble in water, while in acidic pH, chitosan is soluble in water due to protonation of amino groups. The solubility depends on the distribution of free amino and N-acetyl groups (Wu and Bough, 1978; Costa-Pinto et al., 2011). Chitosan is a linear polyelectrolyte at acidic pH. It has high charge density, one charge per glucosamine. The pH and ionic strength have an important impact on the intrinsic viscosity of polyelectrolytes. Chitosan in aqueous acid solution has been surface reacted with polyanion aqueous solutions (heparin, sodium alginate, carboxymethyl chitin, polyacrylic acid) to give polyelectrolyte complexes (Rinaudo and Domard, 1989; Dutkiewicz and Tuora, 1992).
