Cazacu, G.; Totolin, M.; Constantinescu, G.; Ciolacu, D. . Natural polymer modification under radio-frequency electrical discharge conditions. In JOURNAL OF OPTOELECTRONICS AND ADVANCED MATERIALS, 9 (4), pp. 970-974. 2007.

Abstract: Chemical modification of natural polymers (insoluble lignin and cotton cellulose) in radio-frequency cold plasma has been
investigated. The treatments of polymers were carried out in a rotator cold plasma installation specially designed for the R.
F. plasma treatment of powdery materials (i.e. insoluble lignin) and in a statically R.F. plasma device for cotton cellulose.
Spectral, physical and chemical analysis proved the formation of the new products with improved properties.

Keywords: Plasma, Lignin, Cellulose, Natural polymer, Radio-frequency cold plasma
