摘要

碳纳米管作为场发射显示器的电子源得到了广泛的研究。本报告涉及通过丝网印刷形成的耐热碳纳米管电子源。银颗粒通常被添加到碳纳米管印刷浆料中，以确保薄膜中的导电性和/或硬化薄膜。然而，当Ag-CNT膏体在空气中烘烤时，银促进了碳纳米管的燃烧。因此，降低加热过程的温度或在非活性气氛中进行加热过程(Kim et al.， 2001)在fed -panel制造中是必要的，以避免燃烧CNTs。在空气中加热过程是首选的，因为在非活性气氛中加热过程会增加FED的制造成本。众所周知，在碳材料中加入硼可以提高其耐热性(McKee, 1991)。我们尝试通过在Ag-CNT浆料中加入硼来改善碳纳米管电子源的耐热性。

Heatproof improvement of Ag-CNT print-film by boron addition

Carbon nanotubes (CNTs) have been widely studied as electron sources for field emission displays (FEDs). This report concerns heatproofing CNT electron sources formed by screen-printing. Silver-particles are often added to the CNT print paste to secure electro-conductivity in the film and/or to harden the film. However, when the Ag-CNT paste is baked in air, silver promotes the combustion of CNTs. Therefore, to lower the temperature of the heating process or to carry out the heating process in inactive atmospheres (Kim et al., 2001) is necessary in FED-panel-manufacturing, so as not to burn CNTs. The heating process in air is preferred because the heating process in inactive atmospheres raises the FED manufacturing cost. It is known that adding boron to carbon materials improves their heat resistance (McKee, 1991). We made an attempt to improve heatproofing of CNT electron sources by mixing boron into the Ag-CNT paste.
