Abstract
30 o C, pressure 200 Pa). The effects of time (up to 110 s) and power (1 W or 5 W) of the treatment on the values of free energy (γs) of PS and PP samples and γS components — dispersive (γS D ) and polar (γS P ) ones — were determined. With prolonged time of interaction the values of γS and γS P increased, especially in the region of first 35—50 s, while γS D values kept the similar level during the whole time of exposure. The dependence of PP and PS surface resistance on the same parameters as above (time and power of interaction) has been also found. For both polymers this resistance decrease with prolonged time and growing power of exposure.
