Research demonstrates enhanced grafting efficiency using gamma-ray irradiation for silver loading in silicone films, indicating potential for antimicrobial biomedical applications.
In this research, silicone films (SR) were modified by grafting ethylene glycol dicyclopentenyl ether acrylate (EGDEA) through gamma-ray irradiation using both direct and pre-irradiation methods at a dose rate of 10.8 kGy/h, with doses ranging from 10 to 50 kGy. Several techniques, including TGA, DSC, contact angle measurement, mechanical testing, swelling, and FTIR, confirmed the grafting of EGDEA onto SR films. The highest grafting efficiency was achieved at 50 kGy using the direct method. Subsequently, SR-g-EGDEA films were loaded with silver for microbial testing, showing promising results for potential biomedical applications.
