摘要

在本研究中，开发了一种基于催化气相沉积法合成纳米碳纤维状物的自动生产系统。在ni - sno2催化剂的催化下，以粉末状形式合成了螺旋纳米碳纤维之一的纳米碳捻(CNTw)。产率是常规CVD体系和Ni-Cu-In2O3催化剂的5 400倍。将粉状CNTw从基板上刮下来，然后用有机粘结剂粘贴在ITO玻璃基板上，通过胶刮法印刷在ITO玻璃基板上作为电子场发射器。实验结果表明，该薄膜的场发射性能优于Ni-Cu催化剂直接生长的CNTw薄膜。

Preparation of Powdery Carbon Nanotwist and Application to Printed Field Emitter

In the present study, an automatic production system with sequencer control for the synthesis of carbon nanofibriform based on catalytic CVD using a substrate was developed. The carbon nanotwist (CNTw), which is one of the helical carbon nanofibers, was then synthesized in powdery form with an Ni–SnO2-composed catalyst. The production rate was 5 400 times that of the conventional CVD system and Ni–Cu–In2O3 catalyst. The powdery CNTw was easily scraped off the substrate, then pasted with organic binder, and printed by a squeegee method on ITO glass substrate for an electron field emitter. The field emission performance was found to be better than that of the directly grown CNTw film in conventional CVD with Ni–Cu catalyst.
