3D-composite scaffolds from radiation-induced chitosan grafted poly(3-hydroxybutyrate) polyurethane

Both chitosan (CS) and poly(3-hydroxybutyrate) (P(3HB)) are two good options for use in tissue engineering. Some of the advantages of these polymers are biodegradability and non-toxicity. However, the inadequate mechanical properties and hydrophobicity (P3HB) and the low porosity (CS) are examples of shortcomings that restrict its applications. The polysaccharide was grafted onto P(3HB) in a previous work for removing these disadvantages. As of...
