WebIndustrial synthesis of long polymer chains is a somewhat random process and often leaves some unreacted monomers in the final product that can be harmful to the environment. Formaldehyde, styrene (from polystyrene used in food containers, for example), vinyl chloride, and bisphenol-A (from polycarbonates) are known carcinogens. WebTransparent polymer electrolytes are important components in fabricating transparent ionic electroactive polymers (iEAPs). Ionic liquids (ILs) have been widely used as the ionic source for polymeric electrolytes due to their broad electrochemical window and non-volatility.
