The Effect of Introduction of Carbon Nanotubes on the Physicomechanical Properties of Polyvinylacetate

The physicomechanical properties of polyvinylacetate (PVA) with small, no more than 2 wt.%, additions of carbon nanotubes (CNTs) are investigated. Data on the influence of CNT concentration on the differential scanning calorimetry thermograms, thermal destruction, electrical resistance, water vapor sorption, as well as indices of the mechanical properties of PVA/CNT (yield stress, strength, elastic modulus, ultimate elongation, and short-term creep) are reported. A variant of calculation of the elastic constants of the nanocomposite is considered with account of the effect of nanotube agglomeration.
