NOVOSIBIRSK, July 28 – Researchers at Novosibirsk State University (NSU) have developed an innovative method to create an `antistatic` polymer material, designed for the safe handling and transportation of explosive substances.
This new electrically conductive material was developed by specialists at the National Technology Initiative (NTI) Competence Center for `Modeling and Development of New Functional Materials with Specified Properties,` based at NSU. The university has already secured a patent for this invention, with funding provided by the NTI Foundation.
Dmitry Chebochakov, a senior researcher at the NTI Center for New Functional Materials, explained that «this material can be used in the production of items intended for storing and transporting explosive powders and flammable liquids. It`s particularly useful in the petrochemical, chemical, gas, coal, and other industries where conventional plastic containers and vessels pose a risk due to the accumulation of static electricity.»
He elaborated that polyethylene, commonly used in industry, does not conduct electricity and instead accumulates static charges on its surface. This can lead to a spark, potentially causing an explosion, which is especially hazardous when dealing with flammable liquids, gases, or powders.
According to the university, «research conducted by the Center`s scientists has shown that adding multi-walled carbon nanotubes – which are ultra-thin, strong, and electrically conductive structures – significantly alters the polymer`s properties. Crucially, only a small concentration of these nanotubes, ranging from 0.05% to 0.5%, needs to be uniformly distributed within the polymer powder.»
The multi-walled carbon nanotubes essential for this invention were developed and synthesized by researchers at the G. K. Boreskov Institute of Catalysis, part of the Siberian Branch of the Russian Academy of Sciences. The mixing process is carried out in a specialized rotary mixer, ensuring high material homogeneity without compromising the carbon nanotube structure. The mixture is then molded into final products.
Chebochakov emphasized that «the material produced using this new technology has demonstrated stable electrical conductivity, meeting GOST requirements for electrostatic safety. Its conductivity level allows for safe use even in environments with high concentrations of vapors or dust, eliminating the risk of spark generation.» Negotiations are currently underway with potential industrial partners to license this technology for the large-scale production of articles made from this electrically conductive polymer.
