Although many methods are available for the evaluation of the antioxidant capacity of samples presented in the liquid state, typically food and beverages, to date only the 2,2′‐diphenyl‐1‐picrylhydrazyl (DPPH) assay has been applied to the measurement of the antioxidant capacity of solid samples such as active packaging materials. A modified 2,2′‐azino‐bis(3‐ethylbenzothiazoline‐6‐sulfonic acid) diammonium...
Polypyrrole (PPy) and poly(3,4-ethylenedioxythiophene) (PEDOT) powders were prepared using various molar ratios of ammonium persulfate (APS) to their respective monomers. The antioxidant properties of these polymers were investigated through their reaction with the stable and intensely coloured DPPH radical. The DPPH scavenging activity was higher for PPy versus PEDOT, and decreased for both conducting...
