| 摘 要： | 用反相色谱法、电子天平法和ESCA对氧化前后炭纤维的表面性能作了研究。以炭纤维为固定相,正烷烃作探针分子进行了反相色谱实验,求得了炭纤维的吸附等温线。等温线属BrunauerⅡ型,比表面积因氧化而增大。用电子天平法,以正烷烃-甲酰胺-炭纤维体系间接地求得了炭纤维的表面自由能及其分量。表面自由能的极性分量因氧化处理而增大。ESCA的结果表明,经氧化处理后炭纤维表面的O]/C]比增大,但氧化影响仅限于表面,而对距表面5nm以下没有影响。

| Abstract: | The surface properties of carbon fibres, which were oxidized or not, were studied by Inverse Gas Chromatography, electrobalance, and ESCA. IGC experiments were done using carbon fibres as adsorbent and n-alkane as probe. Obtained adsorption isotherms belong to type 2 of Brunauer classification and the specific surface area of carbon fibres is increased by oxidization.The contact angles of formamide on the carbon fibres under n-alkane were measured by means of electrobalance and the surface free energy and its components of the fibres were obtained. The fraction of polarity part of surface free energy is increased by oxidization.It was known from ESCA that the value of O]/C] is increased after oxidization, but the influence is only on the surface. 5 nm beneath the surface, oxidization had no influence to the ratio of O]/C]. |
