- Abstract text
Melamine sponges(MS) are well known as oil-absorbing materials, extensively studied in order to handle the environmental issues caused by oil leakage and emission of chemical reagents. And carbon nanotubes (CNTs) are one of the most fascinating materials in the field of nanotechnology due to their outstanding mechanical, chemical and electronic properties.[2-4] Methods for CNT-synthesis always require feed stock gases, vacuum, high temperature chamber, inert atmosphere and long process time. [5, 6] Herein, CNT-synthesis as well as new surface modification methods were studied using MS as carbon source and nickel acetate as catalyst.
Experiment and Result
In the present study we show that it is possible to grow CNTs within 10 s inside a microwave oven using melamine sponge as carbon source and nickel acetate as catalyst. Figure 1 shows the SEM images of the CNTs synthesized in just 10 s of microwave irradiation of melamine sponge loaded with nickel acetate in presence of the graphene aerogel. It can be seen from Figure 1a that a large number of CNTs were grown on the melamine sponge skeletons. At the top of the CNTs, the nickel catalysts were clearly observed (Figure 1b). As shown in Figure 1c-d, the diameter of CNTs prepared by microwave irradiation was about 200-300 nm.
