Description The modern technologies often require modification of solid material surfaces with keeping desired bulk properties. To control the surface properties of solids the atmospheric- pressure plasma can be very useful. In this work the thin hy- drophobic protective films were deposited on the paper sur- face using atmospheric-pressure surface barrier discharge. Films were deposited from the mixture of the nitrogen with C4F8. The plasma properties were investigated by means of optical emission spectroscopy. The properties of samples were investigated by means of colorimetric measurements such as whiteness, yellowness or brightness tests. The surface energy of the thin films was investigated by means of contact angle measurements. The sample properties were measured in as-deposited state and in UV-exposed state.
