摘要:
 碳纳米管作为一维碳纳米材料,具有十分独特的结构与物理化学性质.近年来,人们开始着重研究碳纳米管的内部填充与物质传输的性质,因此,合成高质量,高通透性的碳纳米管具有重要的意义.采用电子束蒸镀催化剂CVD法制备碳纳米管阵列,并且引入了水蒸汽用以刻蚀多余的无定型碳,最终合成了高质量,高通透性的碳纳米管阵列.碳管内径主要分布在8 nm到15 nm之间,高度可达在100 μm以上,最高可达厘米级别,管壁厚度一般在1.2~2 nm之间.进一步通过环氧树脂包埋结合微切片技术,制备出取向碳纳米管阵列/环氧树脂多孔复合膜,通过一系列的测试证明合成的复合膜中碳纳米管保持了高度取向性,同时具有良好的通透性并且没有宏观裂缝的出现,这保证了复合膜中碳纳米管是唯一的物质传输通道,为进一步研究碳纳米管的内部填充与修饰,以及碳纳米管的内部输运行为奠定了基础.
Abstract:
 As a kind of one dimension carbon nano­material,carbon nanotubes(CNTs)have very unique structure,physical and chemical properties.People began to focus on the internal filling and mass transport properties of carbon nanotube recently.Thus,the synthesis of carbon nanotube array with high quality and permeability comes to be of great significance.The CVD method was used in our experiment to obtain the aligned CNT array assisted by the water vapor which was used to etch the amorphous carbon.The carbon nanotube array with high­quality was successfully synthesized with the inner diameter between 8 nm to 15 nm and the height of about 100 micrometers.The thickness of the CNT wall is generally between 1.2 nm to 2 nm.In addition we prepared carbon nanotube array/epoxy composite porous membrane after a microtome­cut process.The good permeability and crack­free structure of CNTs membrane ensure that the carbon nanotubes to be the only channel for mass transportation.This builds up a good basis for the study on the internal filling,internal mass transport behavior of carbon nanotubes.
