탄소섬유 표면에서의 전기중합: 연속공정

Electropolymerization onto the Surface of Graphite Fibers : A Continuous Process

초록

Glycidyl acrylate와 methyl acrylate의 공중합체를 탄소섬유의 표면에 연속전기중합법을 이용하여 코팅하였다. 전기중합 개시반웅 메카니즘을 규명하기 위해 단량체-용매-전해질 시스템에 대한 cyclic voltammetry 측정을 하였는데 수소이온의 환원만 관찰되었다. 공정 변수인 전유, 반응시간, 단량체 농도, 전해질 농도, 교반 속도의 영향에 대해 조사하였다. 무게 증가 속도는 전류와 단량체의 농도에 비례하였고 전류가 일정할 때 전해질 농도의 영향은 없었다. 일정량의 전류 이상에서는 무게 증가가 전류와 무관하였다. 코팅된 고분자의 분자량은 전류에 반비례하였다.

Copolymer of glycidyl acrylate and methyl acrylate was coated on the surface of graphite fibers by using continuous electropolymerization technique. Cyclic voltammetric study of monomer-solvent-electrolyte system was done to determine the initiation mechanism. Only reduction of hydrogen ions was observed. The processing parameters in terms of current, reaction time, concentration of comonomer, concentration of supporting electrolyte and agitation speed were investigated. The initial rate of weight gain was proportional to current and concentration of the comonomer, but concentration of the supporting electrolyte had no effect when current was controlled. Above a certain amount of current, the weight gain had no relation with the current. The molecular weight of coated polymer was inversely proportional to the current applied.

Keywords:electropolymerization;carbon fiber;weight gain
