| 논문초록 | Eumelanin pigments are the broad class of biopolymers found in many living organisms, which consist of the disordered heterogeneous aromatic oligomer networks. The variations of eumelanins impact the materials functionalities such as optical, optoelectrical, and electrochemical properties. Microstructure and chemical composition of subunits have been studied intensively, however, mesoscopic structure with arrangement of chemical functional groups have not been examined yet. It was also found that ions utilize the meso scale protomolecule as a pathway during charge transport. This study will address open questions regarding how chemical functionalities, and meso-scale structures affect charge transport through eumelanins by electrochemical transport of monovalent cations. The finding would allow eumelanin pigments to be transformed into versatile biopolymers that could serve as the biodegradable electrochemical energy storages. |
