Investigation of influence of barrier discharge plasma on barium titanate particle doped polyethylene by DSC method


Composite films based on high-density polyethylene and barium titanate particles before and after treatment with a dielectric barrier gas discharge were studied by differential scanning calorimetry. The values of critical temperatures, changes in entropy, enthalpy, and degree of crystallinity before and after the action of the gas discharge are found. It is shown that the critical temperature after the action of a gas discharge decreases during heating, and increases during cooling, except for the concentration of barium titanate particles of 5 vol. %. In addition, the change in entropy and enthalpy during discharge processing increases as well as the degree of crystallinity. As the filler concentration increases, the change in enthalpy, entropy, and the degree of crystallinity decrease.

Keywords: barium titanate, high density polyethylene, dielectric barrier discharge plasma; enthalpy, entropy, crystallinity.
