Study on the Gradient Surface of Carboxylic Acid Group Using Corona Discharge Treatment and Subsequent Graft Polymerization

코로나 방전처리와 그라프트 중합에 의한 카르복시산기의 기울기 표면 제조에 관한 연구

Carboxylic acid group gradient surface where the density of carboxylic acid groups changes gradually along the sample length was prepared. Carboxylic acid group gradient surface was produced by the treatment of low density polyethylene sheet using a corona with gradually increasing power, followed by the grad polymerization of acrylic acid. The prepared gradient surface was characterized by the measurement of water contact angle, Fourier-transform infrared spectroscopy in the attenuated total reflectance mode, and electron spectroscopy for chemical analysis.
