General description

Hydroxymethyl EDOT (EDT-methanol) is a conjugated polymer that is used as a precursor of ethylenedioxythiophene (EDOT). The hydroxymethyl groups in the EDOT monomers enhance the electro-polymerization in an aqueous solution to form an electro-active hydrophilic polymer.

Application

EDOT derivative useful in preparation of functional electroactive polymers
EDT-methanol can functionalize poly(L-lactic acid) by using organometallic polymerization, which can be used to form biodegradable and conducting macromonomers for biomedical applications. It can be polymerized to form poly(hydroxymethyl EDOT) based films, which may be incorporated with silver nanoparticles to form nanocomposites on polyethylene terephthalate (PET) for flexible plastic devices.
