Infrared spectra, differential scanning calorimetry and mechanical properties of polyethylene doped with CaGa2S4:Eu+2


High-density polyethylene with the additive of CaGa2S4:Eu+2 particles of different concentrations is investigated by infrared spectroscopy, differential scanning calorimetry and strength testing methods. It was shown that the presence of particles leads to an increase in the effective infrared absorption associated with an increase in scattering, a decrease in the heat of transition, and an increase in the ordering of the system. In this case, the yield threshold decreases with a simultaneous increase in the elastic modulus.

Keywords: phosphor, high density polyethylene, composite material.
