A PLA plastic filament is continuously pulled at a velocity of 4 mm/s through the discharge plasma at a discharge current of 0.7–3 mA. The water contact wetting angle is shown to decrease from 8° to 44°, the free surface energy is shown to increase from 32.28 to 56.84 mJ/m<sup>2</sup>.</p></abstract><trans-abstract xml:lang="ru"><p>Экспериментально продемонстрирована модификация свойств поверхности термопластичных полимеров, в частности, пластиковых нитей Polylactic Acid (PLA), путем их обработки в плазменной трехэлектродной трубке низкотемпературной аргоновой плазмой объемного самостоятельного тлеющего разряда с диэлектрическим барьером при атмосферном давлении. Пластиковая нить PLA непрерывно протягивается со скоростью 4 мм/с через плазму разряда при токе разряда 0.7–3 мА.
