碳纤维表面官能团均一化及其表面能

天空硼氢化钠（NaBH4)、四氢铝锂（LiAlh4)对氧化后碳纤维表面官司能团的还原作用，借助X光光电子能谱、表面能测试，研究氧化、还原后碳纤维表面官能团含量的变化，以及其与表面能的关系，结果表明，四氢铝锂还原有利于获得表面官能团较均一的碳纤维，且不影响碳纤维表面能。碳纤维的表面能与其表面含氧官能团有关系，但并不与具体哪种官能团有明显直接关系。

Homogenization of Functional Groups on Surface of Carbon Fiber and Its Surface Energy

A study is made on the reduction of oxidized functional groups on carbon fiber by sodium borohydride and lithium tetrahydroaluminate.With the help of X ray photoelectron spectroscopy and surface energy test,the study is made on the change of functional group content on surface of carbon fiber after oxidation and reduction and also on their relation with surface energy.As shown by the results,reduction by lithium tetra hydroaluminate is advantageous to the acquisition of carbon fiber with fairly homogeneously surface function al groups,but it does not affect surface energy of carbon fiber.Surface energy of carbon fiber relates to oxygen containing functional groups on surface of carbon fiber,but it has not obviously direct relation with which kinds of specific functional groups.
