Hemoglobin-mediated synthesis of PEDOT:PSS: enhancing conductivity through biological oxidants

Biomater Sci. 2015 Mar;3(3):442-5. doi: 10.1039/c4bm00338a. Epub 2015 Jan 13.

Abstract

Hemoglobin- and catalase-polymerized

Pedot: PSS were characterized by X-ray photoelectron spectroscopy, visible and near-IR spectroscopy, FTIR, and ESR. Hemoglobin-polymerized

Pedot: PSS possesses bipolarons, while catalase-polymerized

Pedot: PSS is dominated by polarons. Use of heme-bound iron as an oxidant yields

Pedot: PSS with conductivity of 19.5 S cm(-1) in a single-step aqueous reaction.
