Low-frequency dielectric spectroscopy was used to study polymer composites with a piezoelectric filler. In a wide frequency range (ν= 25 × 106 Hz) and temperature range (273-423 K), the dielectric characteristics (εand tg δ) and electrical conductivity (σ) of polymer composites with a piezoelectric filler were investigated. The dependences of ε and tg δ, and son the concentration (up to 10 vol%) of filler, the frequency of the electric field, and temperature were studied. It was established that the introduction into high-density polyethylene of PKR-3M segnetopiezoelectric filler of the lead zirconate titanate family has a considerable effect on the given characteristics and changes the form of the dependences tg δ(ν), tg δ(T),ε(T), and σ(T). The variance dependence σ(ν) satisfies the condition σ ~ ns and exhibits two linear sections with parameters S ≈ 0.8 and σ > 1.2 respectively. ©2013 SmithersRapra Technology.

An examination was made of the effect of titanium dioxide (nano-TiO2, "Showa Denko") on the physicomechanical properties of low-density polyethylene (LDPE). It was established that LDPE specimens filled with industrial titanium dioxide TiO2 of micron size and with nano-TiO2 "Showa Denko" exhibit different physicomechanical properties after composite preparation and thermooxidative ageing. In spite of a certain reduction in strength and elasticity after milling and pressing, the composite material containing nanopigment exhibits higher heat ageing resistance than material containing standard industrial titanium dioxide. © 2013 Smithers Rapra Technology.

An examination is made of the results of investigating the influence of the concentration of nanoparticles and graft copolymer (modifier) on the main physicomechanical characteristics of styrene plastics. The limiting concentrations of nanoparticles with which the maximum strength properties are achieved are determined. An interpretation of the mechanism of failure of filled polymer composites is given.

Functionally substituted mono-, di-, and polyesters of 3-cyclohexene series acids were synthesised, and their effectiveness as plasticisers/modifiers for epoxy composites based on ED-20 epoxy-bisphenol A resin was studied. © 2012 Smithers Rapra Technology.
