单壁碳纳米管能够强烈吸收光线,尤其是在近红外区域,并能将光能转换成热能.同时,单壁碳纳米管还具有相当大的将热能转换成电能的能力.通过真空过滤方法,将由化学气相沉积生成的单壁碳纳米管阵列制备成单壁碳纳米管膜.根据研究的需要设计了一个简单的单壁碳纳米管膜光伏性质测试实验装置,并在其两端成功地实现了由红外光转换为电压输出.通过功能化步骤,制备了单壁碳纳米管/三聚氰胺甲醛树脂复合材料膜,实验结果表明该复合材料能产生符号相反的输出电压.这预示着单壁碳纳米管及其三聚氰胺甲醛树脂复合材料在光电领域具有良好的应用前景.
Single-walled carbon nanotubes can strongly absorb light, especially in the near-infrared region, and can convert light energy into heat energy.At the same time, single-walled carbon nanotubes also have a considerable ability to convert thermal energy into electrical energy.Through vacuum filtration , A single-walled carbon nanotube film was prepared by single-walled carbon nanotube arrays generated by chemical vapor deposition.A simple experimental device for testing the photovoltaic properties of single-walled carbon nanotube films was designed according to the needs of the research, The conversion from infrared to voltage was achieved.A single-walled carbon nanotube / melamine resin composite membrane was prepared through the functionalization step and the experimental results show that the composite material can produce the opposite sign of the output voltage.This indicates that single-walled carbon Nanotubes and their melamine formaldehyde resin composite materials in the field of optoelectronics has a good prospect.
