【摘要】 普通的表面处理仪难以处理粉体材料,通过加装旋转滚筒,实现了粉体材料的表面改性处理。经过电极的换位、电极极间距的调整,分析了多壁碳纳米管成片料经氧、四氟化碳射频处理后的可浸润性;对粉体材料则采用XPS、红外分析手段,分析了不同状态处理条件下表面氟元素含量的变化情况。研究结果表明:有机玻璃滚筒的引入降低了碳纳米管射频处理效果,只有当电极换位到滚筒的两端后,材料的处理效果才不受影响;粉体碳纳米管处理效果不理想的根本原因在于纳米管本身的强烈团聚,只有解决了团聚问题后,射频处理方能显效。更多还原

【Abstract】 The plsama modification of powder like material has been carried out by adding rotating cylinder in the vacuum vessel.RF plasma has been modified by means of different ways,such as changing the position of poles and varying the distance of two poles,the ability of being soaked by pure water of multiwall carbon nanotube pre-formed in shape of sheet on glass was investigated.As for as its powder form,the fluorine content was examined by method of XPS and IR.The RF plasma discharging condition paralleled that of the sheeted ones.Results reveals that the PMMC cylinder between two parallel disc poles deteriates the effectiveness of RF plasma modification.The negativeness can be cancelled only can two covers of the cylinde be acted as two poles for RF discharging.The powerful tendancy of aggregating is responsible for the low effectivness of powder modification.Only this problem is overcome can the RF plasma treatment lead to good result.更多还原
