- Аннотация: A novel approach to the development of nanocomposite materials based on high-density polyethyleneand an inorganic flame retardant, magnesium hydroxide, via the fundamental strategy of environmentalcrazing of polymers has been advanced. Efficient methods for incorporation of magnesium nitrate as aprecursor into mesoporous polymeric matrices have been proposed, and optimal conditions providing highconversion in situ hydrolysis of magnesium salt to magnesium hydroxide within the confined space of mesopores of polymeric matrixes have been found. As a result of in situ hydrolysis, spherical or needle-shaped magnesium hydroxide nanoparticles are found to be uniformly distributed within the volume of the highdensity polyethylene matrix. The obtained nanocomposite polymeric materials with a low content of magnesium hydroxide nanoparticles (up to 30 wt %) are characterized by reduced flammability and mechanical characteristics comparable to those of the initial polymer.
