Effect of barrier discharge of low-temperature plasma on surface physicochemical properties of polylactic acid

In the present work the effect of oxygen and argon low-temperature plasma was investigated with exposure time 120 s and plasma gas flow rate 60 cm³/s on surface physicochemical properties of polylactic acid obtained by electrospinning. Physical-chemical properties and chemical state of the modified surface layer were investigated by infrared spectroscopy, as well as contact angle by lying drop method and surface structure by using optical microscopy.
