Cyanoacrylate–carbon nanotube arrays are prepared by embedding carbon nanotube (CNT)arrays grown on silicon substrate in cyanoacrylate adhesive. Upon laser treatment,enhanced field emission properties are obtained. Moreover, the binding force between thecarbon nanotubes and the substrate is strengthened by the cyanoacrylate adhesive. Whenthe field emission current is large enough at high electric field, the carbon nanotubescannot be pulled out of the substrate by electric field force. A large field emissioncurrent can be obtained from cyanoacrylate–carbon nanotube arrays at relativelylow voltage just by decreasing the distance between the anode and the cathode.
