Abstract :
In the CNT paste for field emission, PbO frit had a fatal influence on CNTs during firing, resulting in the accelerated decomposition of CNTs. In the thermogravimetric analysis on the mixtures of CNTs and other ingredients, it was evident that CNTs began to burn out at 350degC by reacting with PbO. This problem was overcome by replacing the PbO frit by the lead-free frit such that most of CNTs could survive during firing. Consequently, the emission current density of the CNT paste prepared using the lead-free frit was improved as much as 250%, compared to the PbO-containing CNT paste
