摘　　要：采用丙酮浸泡、瞬时高温处理及氮气保护下高温处理3种工艺对碳纤维表面进行除胶处理,利用场发射扫描(FESEM)、X射线光电子能谱(XPS)、X射线衍射(XRD)、激光拉曼光谱(LRS)等分析测试手段对不同除胶工艺处理的碳纤维性能进行了对比分析。结果表明,3种除胶工艺都不会破坏碳纤维的本体结构,但对碳纤维表面上浆剂的去除具有不同的效果。丙酮浸泡工艺效果不明显,瞬时高温处理在除胶的同时会破坏碳纤维的表面结构。氮气保护下高温处理工艺的设计避免了上浆剂高温裂解产物的残留,防止了碳纤维高温条件下表面性能的破坏,除胶效果最好。Sizing agent on the surface of carbon fibers was removed by immersion in acetone,instant high-temperature treatment and high-temperature treatment in N2.The properties of carbon fibers with different desizing technologies were compared and investigated by field emission scanning electron microscope （FESEM）,X-ray photoelectron spectroscopy （XPS）,X-ray diffraction （XRD）,laser Raman spectra （LRS）.The results show that three dezing technologies do not destroy the bulk structures of carbon fibers,but have different impact on the desizing of sizing agent on the surface of carbon fibers.The desizing effect of the immersion in acetone is not obvious;the instant high-temperature treatment can remove the sizing agent but also destroy the surface microstructure of carbon fibers.The high-temperature treatment in N2 can eliminate the residue of the pyrolytic products of sizing agent and prevent the damage of the surface properties of carbon fibers at high temperature.The high-temperature treatment in N2 is most effective to remove the surface sizing agent.
