摘要

<正>Ultraviolet （UV）-induced graft polymerization of acrylamide （AAm） on polypropylene substrates was successfully conducted using dibenzyl trithiocarbonate （DBTTC） as photoinitiator. It was confirmed by chemical analysis and surface morphology observation with attenuated total reflectance Fourier transform infrared spectroscopy

X-ray photoelectron spectroscopy

and scanning electron microscopy. A possible mechanism for this graft process was presented

which suggested that

under UV irradiation

the C=S bond in DBTTC could split and abstract a hydrogen from the polypropylene surface and a surface free radical was then formed

and initiated the graft polymerization of AAm.
