Fabrication and oil adsorption of carbon nanotube/polyvinylpyrrolidone surface composite.
It needs to assemble the industrial CNT powders into macroscopic porous surface composite to utilize the surface properties of CNTs, as well as to prevent them entering into environments. We demonstrate a method to fabricate the surface composites from CNTs and polyvinylpyrrolidone (PVP) by electrospinning, where CNTs distribute firmly and mainly on the surface PVP nanofibers. The CNTs/PVP surface composites have high pore volume of 10 cc/g and remarkable CNTs load of 98%. Thus the surface composites show high oil adsorption capacity of 0.9~1.1 g/cm3. It can absorb more oil than commercial sponges due to the surface composite swells after absorbing oil. It shows attractive potential application of the CNT/PVP surface composite in oil spill cleanup.
