TI - Polymeric Grafting of Acrylic Acid onto Poly(3-hydroxybutyrate-co-3-hydroxyvalerate): Surface Functionalization for Tissue Engineering Applications N2 - Poly(3-hydroxybutyrate-co-3-hydroxyvalerate)(PHBV)melt processed disks and solvent cast films were modified by graft co-polymerization with acrylic acid (AAc)in methanol solution at ambient temperature using gamma irradiation (dose rate of 4.5 kGy/h). To assess the presence of carboxylic acid groups on the surface, reaction with pentafluorophenol was performed prior to X-ray photoelectron spectroscopy analysis. The grafting yield for all samples increased with monomer concentration (2-15 UR - https://drive.google.com/file/d/17rxRSBCxiebPitdo9REUIvYL88Us_WMG/view?usp=drivesdk ER -
