Evaluation of chemical functionalization of Polylactic Acid as a spacer for surface immobilization of biomacromolecules

Abstract In many applications of polymers should surface modifications and functionalization for use in sensors, biomedical, textiles, protective coating and many others. Since Polylactic acid(PLA) has neutral and poor functional groups surface for immobilization of biomacromolcules such as heparin, functionalization of surface as a spacer layer for bond with is necessary. There are different method for surface functionalization such as plasma treatment, irradiation by UV and gama rays, hydrolysis. In this work used from aminolysis chemical method. Then effects of aminolysis reaction were evaluated through SEM pictures, AFM, Tensile and XRD.
