Opto-electronic properties of the single-walled carbon nanotube film and melamine formaldehyde resin composite

The single-walled carbon nanotube (SWCNT) can strongly absorb light, particularly in the near infrared region, and can convert it into thermal energy, while the SWCNT also has a great capacity of converting thermal energy into electrical energy. In this paper, by means of vacuum filtering, SWCNT film is prepared by SWCNT arrays generated by the chemical vapor deposition. A simple experimental device of SWCNT is designed and the conversion from the infrared light to voltage output is successfully achieved. The SWCNT/melamine formaldehyde resin composite film is prepared by the functional steps. The experimental results show that the composite material can produce an output voltage of opposite sign, which indicates that the SWCNT and melamine formaldehyde resin composite material have good application prospect in the field of photo-electrical applications.
