Notes:
Ablation, water etching and gold coating were studied on poly(ethyleneterephtalate)(PET) exposed to DC Ar plasma for 240 s at 8.3 W power. Au layers were sputtered on pristine andmodified PET and their adhesion and topography were investigated. The roughness and changes oftopography after plasma treatment, subsequent water etching and gold coating were followed usingAFM microscopy. The thicknesses of ablated layer and water dissolved layer were determined usinggravimetry. A nanoindentor was used to perform microstratch tests of sputtered layers. Waterdissolving of thin layer after plasma treatment was confirmed by FTIR spectroscopy. We havefound that under the present experimental conditions ca 30 nm thick layer of PET is plasma ablated.The surface topography changes dramatically and surface roughness increases. Another ca 16 nmthick layer was removed under present laboratory conditions after 24hour water etching. Subsequentcoating with 50 nm thick gold layer increases surface roughness in all cases of surface modification
