In tradition methods, immobilization proteins on carbon nanotubes (CNTs), use acid treatment carbon nanotube(CNTs) to introduction carboxyl; Or utilise inerti a metal, for example: Platinum, gold, silver. But acid treatment will be destroyed carbon nanotube, and utilize inertia metal, its price is more expensive and more difficult to make. So a thesis utilizes plasma treatment to modify CNTs surface to introduction amine groups (NH2) The base key is formed, use pi asma treatment to introduce functional groups replace the traditional method and improve their shortcomings. Research to find out the optimum plasma treatment condition to immobilization of proteins on carbon nanotubes (CNTs). Apply to biology fuel cell in the future. In this experiment, Plasma enhanced chemical vapor deposition (PECVD) system from carbon nanotubes (CNTs) by ammo plasma treatment. Change of plasma treatment time, and utilize the analytical instruments such as scanning electron microscope (SEM), Fourier transform infrared rays (FTIR) and Raman spectroscopy to observe changing of carbon nanotube, we get the results as follow. 1. The CNTs'length reduced by the increasing time of plasma treatment. 2. In the optimum plasma treatment condition, the CNTs quality Increased along with the time. 3. The plasma treatment bind to amino groups incorporated into the CNTs surface.
