METHOD FOR QUICKLY PREPARING CYCLOPENTADIENE-MODIFIED CARBON NANOTUBE IN GAS-SOLID PHASE

摘要

A method for preparing cyclopentadiene-modified carbon nanotubes, comprising: providing cyclopentadiene and carbon nanotubes in a fluidized state; and reacting the mixture of the cyclopentadiene and the carbon nanotubes in a fluidized state at a temperature of 150°C-500°C, wherein the mass ratio of the cyclopentadiene to the carbon nanotubes is 10:1-1:10. The method can be carried out using a fluidized bed reactor, a tubular reactor or a spiral reactor. The method makes full use of the characteristics that the contact area of the preparation device is large, and the rate of mass and heat transfer is high, making the modification reaction more quick and efficient. Meanwhile, the disadvantage of polymerization of the cyclopentadiene itself caused by reacting at a high temperature and for a long time is avoided, and the reaction efficiency is improved.
