제목 Mussel-inspired Synthesis of Inorganic Nanoparticles on Catechol-grafted Polymer Nanofibers
초록 We introduce a facile method to synthesize inorganic nanoparticles on catechol-grafted polymer nanofibers via the strong mussel adhesion and oxidation of catechol moiety that can reduce metal ions through its mild reduction potential. Catechol moiety is chemically grafted to poly(vinylalcohol) (PVA), and then catechol-grafted PVA (PVA-g-ct) is electrospun into nanofibers. PVA-g-ct nanofibers serve as scaffolds for the reduction of metal ions to metal nanoparticles or the deposition of metal oxide nanoparticles. The synthesis and assembly of inorganic nanoparticles are spontaneously generated on PVA-g-ct nanofibers by incubation with inorganic precursor solution under ambient conditions. This mussel-inspired process generates organic-inorganic hybrid nanostructures with three dimensional porous structures, providing a wide range of potential applications for biosensors, catalytic systems, and electronic devices.
