They Obtained Carbon Nanotubes from Waste Plastic Bags. From the University of Adelaide in Australia, Dr. T. Altalhi and colleagues obtained carbon nanotubes using waste plastic bags as a carbon source. The results of the research were published in Carbon. It is a known fact that plastic bags threaten the environment. Many countries are trying to reduce the production of plastic bags that cannot be broken down by organisms. Researchers looking for a solution to the problem showed that nanotubes can be obtained by using the carbon contained in plastic bags. Carbon nanotubes, which consist of atoms arranged in the form of cylinders, whose cross-sectional area is nanometer (billionth of a meter) in diameter, is the most durable material known.
Their density is one-sixth that of steel, but they are hundreds of times stronger than steel. Their electrical, mechanical and thermal properties cause them to be preferred in R&D studies. However, the production processes used today are very complex and the daily production of carbon nanotubes for commercial purposes does not exceed a few grams. In the research, a new method based on chemical vapor precipitation technique was developed for the manufacture of carbon nanotubes. The developed method ensures that waste plastic bags are used in the production of nanotechnology products and prevents them from harming the environment. In addition, no toxic by-products are formed since catalysts and solvents are not used during synthesis.
