Abstract
The effects of water on the mobility of nonionic spin probes in nylon 6 film were investigated by electron spin resonance (ESR) measurements. T50G′, which can be correlated with the glass transition temperature Tg′, decreased with increasing water content. The rotational correlation time decreased with the rise of the water content at a given temperature, indicating an increase of the mobility of the spin probe. Simultaneously the activation energy for rotation decreased. It was found that the rotation of the spin probe becomes easier as the water content increases.
