摘要：
The covalent bonding of amino-terminated molecules was performed onto acrylic acid radiation induced grafting poly(vinylidene fluoride) (PVDF). The polymer was irradiated with different ionizing radiation: swift heavy ions or electrons. The polymerization of acrylic acid was then performed to confer to PVDF carboxyl groups suitable for condensation with the amino groups of the other molecule. Acrylic acid swelling of PVDF films was investigated as a function of temperature and monomer concentration in order to anticipate the best grafting conditions. Grafted and functionalized films were characterized using infrared spectroscopy (transmission and ATR), and weighing measurements. The PVDF-g-PAA films exhibit different structures depending on the monomer concentration. Immobilization of an amino-terminated molecule and a peptide onto PVDF was achieved using water soluble carbodiimide. (C) 2003 Elsevier B.V. All rights reserved.
