A mussel-inspired polydopamine coating as a versatile platform for the in situ synthesis of graphene-based nanocomposites

Abstract

A facile and universal approach to prepare graphene-based nanocomposites by in situ nucleation and growth of diverse noble metals, metal oxides and semiconducting nanoparticles on the surface of RGO is proposed.

Preparation of amine functionalized carbon nanotubes via a bioinspired strategy and their application in Cu2+ removal

“…Very recently, we also demonstrated that well dispersed CNTs could be facilely obtained by surface modification with 3-mercapto-1-propanesulfonic acid sodium salt (MPS), normal dodecanethiol (NDM) and polymers via combination of mussel inspired chemistry and Michael addition reaction [22,23,46]. The surface modification of carbon nanomaterials with biomolecules via mussel inspired chemistry has also been reported recently [47,48]. More importantly, the PDA derivates have also demonstrated to be useful for heavy metal ion removal.…”

Green synthesis of Pt–Au dendrimer-like nanoparticles supported on polydopamine-functionalized graphene and their high performance toward 4- nitrophenol reduction

“…Also, PDA can be easily introduced by the selfpolymerization of dopamine at weakly alkaline pH [20][21][22]. Importantly, dopamine is an eco-friendly reducing agent for the reduction of GO [23][24][25][26][27][28][29].…”

Current Approaches to Designing Nanomaterials Inspired by Mussel Adhesive Proteins

“…The polydopamine coating remains reactive and can form covalent bonds with functional groups (e.g., -NH 2 , -SH, imidazole group), which can be used to graft polymers, initiators, proteins, polysaccharides, oligonucleotides, nanoparticles, growth factors, cells, or metal ions onto the polydopamine-coated surface [70,[152][153][154][155][156]. Catechol's affinity with metal ions has also been exploited to metallize polydopamine coatings though incubating the polydopamine-coated objects in solutions containing these ions (e.g., silver, gold, cupric, and ferric ions) [70,[157][158][159]. During the process, nanoparticles nucleate on the polydopamine coating.…”
