Radiofrequency induced plasma in large-scale plasma reactor
Rok Zaplotnik, Alenka Vesel
Izvirni znanstveni članek
Oznake: radiofrequency discharge;gaseous plasma;large plasma reactor;matching network;
In this contribution we describe the characteristics of an electrical discharge in rarified gas created by dual-excitation coil. By using two parallel and overlapping excitation coils we can achieve a better transfer of the electromagnetic power from the radiofrequency (RF) generator to gaseous plas ...

Advanced method for efficient functionalization of polymers by intermediate free-radical formation with vacuum-ultraviolet radiation and producing superhydrophilic surfaces
Alenka Vesel, Rok Zaplotnik, Miran Mozetič, Nina Recek
Izvirni znanstveni članek
Oznake: plasma treatment;vacuum-ultraviolet radiation treatment;surface functionalization;polymer polyvinyl chloride;vacuum-ultraviolet spectroscopy;vacuum-ultraviolet photons;
An efficient approach for tailoring surface properties of polymers is presented, which enables rapid modification leading to superhydrophilic properties. The approach is based on vacuum-ultraviolet radiation (VUV) pretreatment of the surface to create reactive dangling bonds. This step is followed b ...

Evolution of surface functional groups and aromatic ring degradation upon treatment of polystyrene with hydroxyl radicals
Alenka Vesel, Rok Zaplotnik, Gregor Primc, Miran Mozetič
Izvirni znanstveni članek
Oznake: polistiren;kinetika površinske funkcionalizacije;OH radikali;vpliv doze radikalov;časovni razvoj;polystyrene;surface functionalisation kinetics;OH radicals;
The surface properties of hydrocarbon polymers are inadequate for numerous applications. Hence, they require alteration via functionalisation with desired functional groups. Hydroxyl groups are often preferred, since they enable appropriate polarity for the irreversible grafting of desired molecules ...

Kinetics of surface wettability of aromatic polymers (PET, PS, PEEK, and PPS) upon treatment with neutral oxygen atoms from non-equilibrium oxygen plasma
Alenka Vesel, Rok Zaplotnik, Gregor Primc, Miran Mozetič
Izvirni znanstveni članek
Oznake: polimeri;prevleke;tanke plasti;
The wettability of polymers is usually inadequate to ensure the appropriate spreading of polar liquids and thus enable the required adhesion of coatings. A standard ecologically benign method for increasing the polymer wettability is a brief treatment with a non-equilibrium plasma rich in reactive o ...

Modification of surface morphology of graphite by oxygen plasma treatment
Kristina Eleršič, Ita Junkar, Martina Modic, Rok Zaplotnik, Alenka Vesel, Uroš Cvelbar
Izvirni znanstveni članek
Oznake: graphite;oxygen plasma;scanning electron microscopy;morphology;nanocones;
Samples of highly oriented pyrolitic graphite (HOPG) were exposed to fully dissociated oxygen plasma created by a radiofrequency discharge in pure oxygen. The discharge was powered with a radiofrequency generator operating at the standard industrial frequency of 13.56 MHz and the output power of 100 ...
