THE EFFECT OF NANOCARBON ON THE MECHANICAL PROPERTIES OF HIGH-PRESSURE POLYETHYLENE

New polymer nanocomposites based on high-pressure polyethylene grade 10803-020 and carbon nanotubes were developed, and the conditions for obtaining nanocomposites with optimal physical properties were determined.The primary goal of this work was to incorporate carbon nanotubes into polyethylene to produce nanocomposites with superior properties for construction applications.The composition and concentration of the nanoadditive which led to significant improvement in the electromechanical properties of high-pressure polyethylene were experimentally determined.Nanocarbon was used as a modifying additive.The developed nanocomposite is notable for the first-time introduction of a very small amount of nanocarbon into HPPE, varying within 0.01-0.1 mass %.It was found that including 0.05 mass % nanocarbon in high-pressure polyethylene significantly increases its mechanical strength.The physicochemical changes in the resulting composite materials under electrical discharges in air and UV radiation were studied.It was shown that adding 0.05 mass % nanocarbon significantly enhances the material's resistance to electrical discharges and UV radiation.Considering the characteristics and technical parameters of high-pressure polyethylene + 0.05 mass % nanocarbon, this material can be widely used in various industries, including construction.
