Abstract
The effect of the dispersion of graphite and boron nitride on the mech anical, electrophysical, and friction properties of polymerization-fil led polypropylene-graphite and polypropylene-(boron nitride) compositi ons was studied. It was shown that a dramatic decrease in the dimensio ns of filler particles changes the properties of the composite materia l: strength increases, plasticity and anisotropy decrease, stability t o thermooxidative degradation increases, and friction properties are i mproved. The above phenomena are related to an increase in adhesion in teraction between filler particles and the polymer matrix.
