“…Combining the problem of recycling polymer waste and nanotechnology development has led to the improvement of areas related to waste recycling for the synthesis of nanomaterials, including carbon nanotubes. Carbon nanotubes have the prospect of application for obtaining various types of composite materials [4], flexible heating elements [5] and various other practical applications. Many factors impact on the synthesis of carbon nanomaterials from polymer waste, in particular, polyethylene: polymer type, polymer decomposition temperature, deposition time, presence of catalysts, the atmosphere in which the synthesis is carried out, etc.…”
