摘    要:将活性炭纤维(ACF)和氟气反应制备了氟化活性炭纤维(FACF)。XPS的研究结果表明FACF的碳原子是以sp^3杂化轨道同氟原子形成共价键。αs图分析氮吸附等温线的结果表明,ACF氟化后其比表面积和微孔容积显著降低、微孔宽度基本不变。FACF对水的吸附量极小,微孔表面具有完美的憎水性和高稳定性。

关 键 词:氟化活性炭纤维 憎水性 表面结构 纳米孔 制备

Abstract:Fluorinated activated carbon fibers (FACF) were prepared from activated carbon fiber (ACF) reacting directly with fluorine. The result of XPS showed that carbon atom of FACF was sp 3 hybridization, and was combined with fluorine by covalent bond. The result of as plots for nitrogen adsorption shows that the specific surface area and micropore volume of FACF were remarkably lower than those of ACF, but the micropore width was not changed. The amount of water adsorbed on FACF is small. Fluorinated micropore possesses a perfect hydrophobicity and a high stability.
Keywords:fluorinated activated carbon fiber  hydrophobicity  surface structure  nanospace
