Dopamine-induced silica-polydopamine hybrids with controllable morphology

Chem Commun (Camb). 2014 Apr 7;50(27):3602-5. doi: 10.1039/c3cc49034c.

Abstract

Novel silica-polydopamine hybrids, with controllable morphology, are facilely fabricated in an emulsion system consisting of tetraethyl orthosilicate, dopamine, water, and NaOH under weakly basic conditions (pH 8.5-10). An increase in initial pH favors the formation of nano-structured spherical silica-PDA hybrids from a flocculated structure.
