Optimization of the thickness of a conducting polymer, polyaniline, deposited on the surface of poly(vinyl chloride) membranes: A new way to improve their potentiometric response
Original language description
Repeated depositions of polyaniline (PANI) have been used to control the thickness of the polymeric film deposited on poly(vinyl chloride) (PVC) membrane surface. The oxidation of aniline was carried out in a dispersion mode, i.e. in the presence of poly(N-vinylpyrrolidone) (PVP). Two kinds of PVC were used for this purpose: a non-plasticized PVC for the study of PANI deposition and PVC, plasticized with nitrophenyl octyl ether (NPOE), as a prototype of a liquid membrane electrode. The results of UV-visible and FTIR spectroscopies and electron microscopy showed that (1) the film thickness increased by about equal increments of ~40 nm after each polymerization, and (2) the interface with PVC was constituted by PANI film and adhering PANI-PVP colloidal particles.

Optimalizace tloušťky vodivého polymeru, polyanilinu, poly(vinyl chloridové) membrány: nový způsob ke zlepšování její potenciometrické odezvy
Czech description
Opakovaná depozice polyanilinu (PANI) byla použita pro kontrolu tloušťky polymerního filmu na povrchu poly(vinyl chloridové) membrány. Oxidace anilinu se uskutečnila za přítomnosti poly(N-vinylpyrrolidonu) (PVP). Polymerizace se prováděla na povrchu membrány jak neplastifikované, tak plastifikované nitrophenyl octylovým etherem (NPOE). Výsledky měření UV-vis, FTIR spektroskopii a elektronového mikroskopu ukázali, že (1) po každé polymerace tloušťka polymerního filmu se zvětšovala ~40 nm, (2) po nanesenípolymeru PVC povrch obsahoval kromě PANI i PANI-PVP koloidní částice.
