Preparation of a novel functional SiC@polythiophene nanocomposite of a core–shell morphology

Abstract

The novel functional COOH SiC@PTAA nanocomposite (NC) of a core–shell morphology was prepared using a chemical oxidative polymerization of a 3-thiopheneacetic acid (TAA) monomer in the presence of modified core SiC-grafted-thiophene (SiC-T) nanoparticles (NPs). The surface-localized thiophene groups on the core SiC-T NPs acted as nucleation points for the polymerization of the TAA monomer, and thus a phase separation of the core and the shell components was not observed. Finally, the reactivity of the functional COOH PTAA shell of the resulting NC of a core–shell morphology was evaluated by reaction with 1,4-diaminobutane through an amidation reaction.
