Scaffolds were prepared by the method of lyophilization from solution at 2% (m / v) chitosan in 1% acetic acid (v / v), adding graphene oxide (GO) to 0.05% (m / v ) sorbitol and employing a 3% (m / v) as plasticizer. Modulus of elasticity, tensile strength and deformation with the aim of evaluating the influence of GO and sorbitol on the mechanical properties of the polymer was measured.
