Investigating the thermal properties of polyethylene plasma modified by using unconventional chemical vapors


In this work, we presented plasma modification of low-density polyethylene (PE) powder using unconventional chemicals. This work focused on the thermal behavior of modified PE. Plasma modification of PE was carried out using unconventional chemical vapor i.e., acetone, toluene, ethanol, methanol, isopropanol, and chloroform, respectively. For all the process, the modification time was kept constant for 2 min. Chamber pressure of 100 Pa was used for the study. The thermal behavior of the plasma-modified and unmodified PE was carried out by differential scanning calorimetry and thermogravimetric analysis. We have found that there is a maximum improvement of crystallinity and thermal stability of PE when ethanol is used for plasma modification. Results obtained from DSC showed that plasma modification of PE in ethanol vapors increases the crystallinity of the PE without damaging the surface properties. Thermal stability of PE plasma modified in ethanol gives maximum thermal improvement to almost 25 °C at 5 mass% mass loss compared to unmodified PE.
