자외선 조사에 의한 아크릴아마이드의 PAN에 대한 표면그라프트 공중합
Surface Graft Copolymerization of Acrylamide onto Polyacrylonitrile by UV Irradiation
초록
Surface graft copolymerization of acrylamide(Ahn) onto polyacrylonitrile (PAN) by using benzophenone(BP) as a photosensitizer under W irradiation was carried out to improve moisture regain of PAN. The effects of reaction conditions such as monomer concentration, photosensitizer concentration, W irradiation time and immersion time on grafting were investigated. The percent grafting increased with increasing the monomer concentration, W irradiation time and immersion time. It was found !hat there are increases in the percent grafting up to about 0.9% with increases in the percent grafting with further increasing BP concentration. The moisture regain increased up to 5% and the contact angle decreased as the percent grafting increased. The static electricity of PAN-g-AAm films decreased with increasing the percent grafting.
