EPR investigation of nanosized silver particles in polymer composites
Abstract
In this work new paramagnetic composite materials based on (co)polymers of 1-vinyl-1,2,4-triazole containing silver nanoparticles were investigated and characterized. It was found that form and width of electron paramagnetic resonance (EPR) signals for silver particles of nanocomposites obtained depend on microwave power. Also the effect of temperature on intensity, g-factor and width of signal silver clusters was determined.
