Graphite Fiber Surface Analysis Using X-ray Photoelectron Spectrocopy

초록

XPS를 이용하여 상업적으로 생산되는 흑연섬유의 표면산화상태에 관한 화학정보를 조사하였다. 이들 섬유들의 표면 관능기를 변화시키기 위하여 진공하에서 가열하거나 전기화학적으로 처리하였다. 피이크 디콘볼루션에 의하면 섬유표면은 히드록시기 또는 에테르기, 카르보닐기 및 카르복실산기로 구성되어 있으며 이들의 구성비는 표면처리에 따라 현저한 차이를 보였다. 아르곤이온 에칭 실험결과 섬유와 매트릭스간의 계면접착력을 증가시키기 위하여 상업적으로 처리된 섬유에는 대부분의 산소관능기가 표면에만 존재하는 표면이질성이 밝혀졌다.

X-ray photoelectron spectroscopy(XPS) was used to obtain the detailed chemical bonding information on surface oxides of the surface-modified graphite fibers. The commercial fibers were further heat-treated under vacuum or electrochemically treated to modify the surface. Deconvolution results of XPS spectra showed that the surface of the fibers was mostly composed of hydroxyl or ether, carbonyl and carboxylic acid groups but their compositions were varied upon surface treatments. An ionized argon etching experiment revealed surface heterogeneity that most oxygen was present only on the surfaces of commercially treated fibers, which results in improved adhesion between the fibers and matrices.
