Investigation of electrical and optical properties of polyvinyl acetate doped with some polymers

摘要

Polyglycerol (PG) and polytriethanolamine-(FTEA) have been prepared. The electrical resistivity (rho) and the optical absorption of polyvinylacetate (PVAc) doped with polyglycerol (PG), polyaniline (PA), and polytriethanolamine (PTEA) have been studied. It was found that the conduction was mainly ionic in the temperature range from 20 to 120degreesC. The resistivity decreased with the increase of the dopant cocentration. The optical absorption spectra were determined in the wavelength range 400-2500 nm. The analysis of the absorption spectra showed that the intensity of the bands is remarkably affected by the dopant concentration. The optical energy gap of puree PVAc and the samples containing different dopants were estimated. (C) 2002 Wiley Periodicals, Inc. [References: 12]
