摘要
聚苯胺(PANI)是由多孔的无定形硬碳组成。以二甲苯为碳前驱体源,Fe/SiO2纳米颗粒为催化剂,采用低压化学气相沉积(LPCVD)法制备了碳纳米管。在热解聚苯胺的孔内生长的碳纳米管的孔隙挤压和沉积的碳颗粒粘附使碳纳米管紧贴在基体上。研究了产品的场发射特性:导通场为1.6 ~ 2.6 v /mum,阈值场为5.3 ~ 8.8 v /mum,增强系数为4540 ~ 7200
Preparation and Field Emission Properties of Carbon Nanotubes Grown on Novel Porous Pyrolyzed Polyaniline Substrate
The pyrolyzed polyaniline (PANI) consisted of amorphous hard carbon full of pores. Carbon nanotubes (CNTs) grew on pyrolyzed PANI substrate with the rough surface containing some pores using a low pressure chemistry vapor deposition (LPCVD) method with xylene as a carbon precursor source and Fe/SiO2 nanoparticles as catalyst. The pore extrusion and the deposited carbon particles adhesion of CNTs growing inside the pore of pyrolyzed PANI make CNTs mount to the substrate tightly. The field emission properties of production were investigated: the turn-on field is 1.6-2.6V/mum, the threshold field is 5.3-8.8V/mum and the enhancement factor is 4540-7200
