Chitosanis one of the most abundant and biodegradable polymer. Chitosan is anamino groups in the polymeric chainsolubility, reactivity, biodegradability and adsorption of many substrates, therefore on the composition of partially or fullydeacetylated D-glucosamine units.Chitosan is naturally occurring biopolymer with low mechanical properties. It is used as food packing material and various biomedical applications.Poly (methyl methacrylate) is polymer with high mechanical properties. In this work, chitosan film is coated with Poly (methyl methacrylate) bysol-gel technique to improve the mechanical properties and also investigates the interaction by strong hydrogen bond in coated substrate.
