The effect of barrier discharge plasma on the thermophysical, dielectric, conductivity and photoluminescent properties of CaGa2S4:Eu2+doped low-density polyethylene have been investigated. It is shown that the enthalpy and entropy of melting and solidification decrease sharply with the inclusion of filler (3 vol%) and then increase with increasing filler concentration. At the same time, these physical quantities increases in all cases after exposure to the gas discharge. This increase is negligible for pure polyethylene, but significant for composites. With increasing filler concentration, the dielectric permittivity increases and agrees well with the Maxwell–Garnett theory. It is shown that the conductivity has a hopping character and mainly increases with increasing filler concentration. Dielectric permittivity increases and conductivity as well as photoluminescence decrease after the action of gas discharge.
