Effect of electric discharge plasma on thermophysical properties of HDPE-BN composites		  pdf 

ABSTRACT

The effect of dielectric barrier discharge plasma before and after modification on thermo-physical properties of composites based on high density polyethylene and boron nitride particles was studied. It has been established that with an increase in the volume fraction of the filler, the entropy and enthalpy decrease, except for 3vol.% and 7 vol.%. The entropy and enthalpy increase after the plasma while the critical temperature almost does not change. The degree of crystallinity decreases after plasma treatment.

Keywords: boron nitride, high density polyethylene, dielectric barrier discharge plasma; difference of enthalpy and entropy of composites, crystallinity.
