Luminescent Properties of Nanocomposites on the Basis of Isotactic Polypropylene and Zirconium Dioxide Nanoparticles

Hajiyeva FV, Ramazanov MA and Maharramov AM

At the paper studied luminescent properties of nanocomposites on the basis isotactic polypropylene and zirconium dioxide nanoparticles. Shown that change of nanocomposite colour and maximum amplitude of UV spectres depend on ZrO2 nanoparticles sizes in polypropylene. Found that mean-square roughness of PP +1% ZrO2 composition surface in dependence of cooling rate β changes, i.e. for the samples at regime β1=20 deg/min the roughness is 40-60 nm, whereas for the samples prepared at β2=2 deg/min the roughness is 150-220 nm. Shown that polypropylene matrix works as chemically stable preservative of nanoparticles, preserving its spectral peculiarities. Sufficiently strong interphases interactions between PP matrix and ZrO2 nanoparticles change its luminescent properties.
