In this paper, we report a two steps low pressure plasma treatment composed by an etching, optimized for the nano-texturing of polycarbonate to improve its anti-reflective property by simulating the so called “Moth eye” effect, and by a plasma enhanced-chemical vapour deposition process to enhance the scratch resistance. Reflectance/transmittance measurements showed that this approach is able to increase the anti-reflective property of the polycarbonate without drastically damaging its transmittance, while scratching test by “car wash” simulator demonstrated the increase of scrape resistance. The haze test confirmed the transparency of the plasma treated polymer also after washing.

Abstract
In this paper, we report a two steps low pressure plasma treatment composed by an etching, optimized for the nano-texturing of polycarbonate to improve its anti-reflective property by simulating the so called “Moth eye” effect, and by a plasma enhanced-chemical vapour deposition process to enhance the scratch resistance. Reflectance/transmittance measurements showed that this approach is able to increase the anti-reflective property of the polycarbonate without drastically damaging its transmittance, while scratching test by “car wash” simulator demonstrated the increase of scrape resistance. The haze test confirmed the transparency of the plasma treated polymer also after washing.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
