Abstract:<\/p>\n

Electrical conductivity, tensile strenght and elongation at break of the composites on the base of cross-linked polyurethanes with multiwalled carbon nanotubes were investigated depending on the concentration of fillers. It was shown at the filler content of 0,0034\u00a0vol. the electrical conductivity was increased from 10<\/em>-10<\/em>\u00a0(for polyurethane matrix) to 10<\/em>-6<\/em>\u00a0S\/cm (with filler content of 0,0052\u00a0vol.).This effect caused of electrical percolation treshold. It was shown that the introduction of carbon nanotubes leads to growing of tensile strength and decreasing of elongation at break of polyurethane composites. In particular, the increasing of tensile strength passes through the maximum with filler content 0,0042\u00a0vol.. And at this point the value of tensile strenght is equal to 14,3 MPa (the tensile strength for original polyurethane matrix is equal to 4,3\u00a0MPa). In contrast, the elongation at break decreases with increasing of filler concentration (from 837\u00a0% for original polyurethane to 423 % at the filler content is equal 0,0047\u00a0vol.) that causes by reinforcing effect of carbon nanotubes in polyurethane matrix.<\/em><\/p>\n
