Název v původním jazyce

IR Laser Ablation of Poly(vinyl chloride): Formation of Monomer and Deposition of Nanofibers of Chlorinated Polyhydrocarbon

Popis výsledku v původním jazyce

IR laser-induced ablation of poly(vinyl chloride) was examined at different irradiation conditions and its volatile and solid products were characterized by mass, infrared, UV and X-ray photoelectron spectroscopy, electron microscopy and thermal gravimetry. It is demonstrated that the major component among the volatile products is monomeric vinyl chloride and that the process affords deposition of Cl-containing polymeric films. The proportion between the volatile and solid products as well as the natureof the deposited films at different laser fluence has been examined. We show that the deposited films incorporate less Cl atoms than poly(vinyl chloride) and that they initially contain conjugated C=C bonds and incorporate nanofiber and nanoneckless features. The process represents the first example of thermal degradation of poly(vinylchloride) into monomer and it makes possible to fabricate crosslinked Cl-containing intractable polymer films.
