Preparation of conducting core-shell nanoparticles based on dendritic hexadecaaniline-C60-poly(dimethylsiloxane) conjugates

A new class of macromolecular core-shell-like elastomeric conducting nanoparticles based on triblock (A(16))(5)-C-60-PDMS-C-60-(A(16))(5) analogous dendritic structure were fabricated using flexible poly(dimethylsiloxane) (PDMS) as the elastomeric segment in linking with conducting C-60-(hexadecaaniline)(5) [C-60(A(16))(5)] subunits. In polar solvents, the PDMS segments coagulated into nanosized particles encapsulated with self-assembled C-60(A(16))(5) shell. Spherical particles in a diameter of 50-80 nm were achieved and observed in scanning electron micrographs.
