Liquid and Solid-State NMR study of the electron irradiated Polystyrene

Irradiation of polymer widely studied due to improve and control its own properties such as mechanical strength, color and electrical conductivity. Especially, irradiated polystyrene (PS) has shown impressive performance in bioassay and biosensor, for example increase cell adhesion which is important properties for the biochip. However, although several propose has been reported about PS radiolysis, exact chemical modification process remains unclear. In this paper, we analyzed the electron irradiated PS using liquid and solid proton nuclear magnetic resonance spectroscopy (NMR) which is a useful to define the chemical configuration
