Experimental study demonstrates altered surface viscoelasticity in plasma-treated low-density polyethylene, indicating permanent microstructural hardening under high-power exposure.
Nanoscale dynamic mechanical analysis (nanoDMA) was used to determine changes in surface viscoelastic properties of low-density polyethylene (LDPE) due to Ar plasma treatment. The experimental results show that the exposure of LDPE to high-power plasma produces a more solid-like response compared to low-power plasma. In addition, high-power plasma treatment results in permanent modification of the near-surface microstructure of LDPE, while low-power plasma treatment yields a microstructure that exhibits time-dependent viscoelastic properties. The results of this study show that nanoDMA is an effective method for evaluating changes in surface viscoelastic properties of polymers due to modification of the near-surface microstructure by inert plasma treatment.
