Abstract
A novel modified poly(DL-lactic acid) (PDLLA) was obtained by covalent grafting of maleic anhydride, hexanediamine and GRGDY onto the backbone of PDLLA to improve the hydrophilicity of PDLLA; Then, the modified PDLLA/HA porous composite was prepared. The cell affinity and cell growth were improved. FTIR, 13C NMR, DSC, AAA and SEM were used to characterize the composite material. The hydrophilicity and interfacial compatibility of composite were tested
