초록
본 연구에서는 피치계 탄소섬유의 표면처리를 위하여 탄소섬유를 산에 담지하여 전자선을 조사하고 각 처리 조건에 따른 탄소섬유의 표면 변화를 평가하였다. 산 담지용액은 질산과 과산화수소를 사용하였으며 전자선 조사량은 200, 400 kGy로 하였다. 과산화수소 담지보다 질산 담지가 탄소섬유 표면에 더 많은 산소관능기를 도입시켰으며, 질소관능기도 탄소섬유표면에 도입되었다. 또한 전자선 조사량이 증가하면 탄소섬유에 도입되는 산소관능기가 증가하는 것을 알 수 있었다. 이는 과산화수소보다 질산이 전자선 조사에 의한 산화성 물질의 형성이 용이하고, 전자선 조사 에너지가 클수록 산화성 물질이 더 많이 형성되기 때문이다. 또한 질산 용액에서 전자선 조사에 의하여 생성되는 NO2 라디칼이 C-OH 관능기를 C=O 관능기로 산화시키는 반응이 주로 일어나므로 질산 담지 시 C=O 관능기의 생성이 유리한 것으로 나타났다.
In this study, pitch-based carbon fibers in the acid were radiated with an electron beam to modify their surface, and surface changes were investigated according to each treatment conditions. Nitric acid and hydrogen peroxide were used as a drenched acidic solution and an electron beam dose was set to 200 and 400 kGy. The use of nitric acid introduced more oxygen functional groups on carbon fiber surfaces than that of using hydrogen peroxide, and also introduced nitrogen functional groups into the carbon fiber surface. In addition, oxygen functional groups introduced on carbon fiber surface increased as the electron beam dose increased due to the fact that the oxidizing material can be easily formed by e-beam radiation in nitric acid than the hydrogen peroxide, and also the higher energy electron beam dose can help forming more oxidizing materials. Moreover, the generation of C=O functional groups was favorable when using nitric acid because oxidizing C-OH functional groups to the C=O functional groups mainly occurred by NO2 radicals generated by the electron beam radiation in a nitric acid solution.
