PLASMA-ENHANCED CHEMICAL VAPOR DEPOSITION OF OCTAFLUOROCYCLOBUTANE ONTO CARBONYL IRON PARTICLES

Popis výsledku v původním jazyce

Conformal films of fluoropolymer have been made onto carbonyl iron microparticles by plasma-enhanced chemical vapor deposition of octafluorocyclobutane in this study. RF plasma reactor with a frequency of 40 kHz and rotating barrel fixed between the twodischarge electrodes arrangement was used to achieve a uniform surface modification of particles. The samples were treated for different times and various RF powers. Chemical changes in the surface composition plasma modifications were, subsequently, determined using high-resolution X-ray photoelectron spectroscopy, while the surface texture was analyzed via scanning electron microscopy and atomic force microscopy. The results revealed successful fluorination of carbonyl iron particles with a maximum fluorine content of 2.9 %. The fluorine atomic concentrations on the plasma treated CI particles surface increased with increasing treatment time until approximately 400 s while remained almost constant afterwards. The concentration of fluo
