Effect of plasma treatment on hydrophobicity and barrier property of polylactic acid

In this work, we investigated the influence of SF6 plasma generated by an inductively coupled discharge on the hydrophobicity and barrier properties of poly(lactic acid), PLA. It was found that SF6 plasma enhanced the hydrophobicity of PLA as observed in the increase of the water contact angle. Wate...
