Abstract

Present study refers to the influence of the percentage of nitrogen mass flow rate within a constant helium flow on the polymer surface treated by DBD plasma produced in He/N2 gas mixture. The DBD plasma has been characterised by rotational temperature measured from molecular spectra of + 2N molecules and intensities of spectral lines of He, N2, + 2N and OH respectively while the electrical parameters of the DBD were measured as amplitude of both discharge voltage and discharge current. Modification of the surface properties produced by the DBD plasma on polymer (PET+TiO2) sample has been determined by AFM technique and measurements of the contact angle..
