Application of bio-inspired adhesives for the next-generation secondary battery materials

Abstract

Mussels, Mytilus deulis, are well-known marine creatures for its characteristic adhesive properties in aqueous environment. The adhesive property of marine mussels is come from catechol (DOPA) and amine (lysine) moieties, therefore, catecholamine has been widely used for surface or polymer modifications. In this thesis, nanomechanics of poly(catecholamine) in aqueous solution was described. In addition, biomimetic approaches not only mussel byssus but also melanin in human eye and mucin in digestive organs were adjusted to energy storage devices for preventing the rapid capacity decay of secondary batteries. The present investigation provides a message that simple treatments inspired by nature could be effective solutions to the problems in various energy storage devices.
