Magnetic polyorganosiloxane core–shell nanoparticles: Synthesis, characterization and magnetic fractionation
Abstact Here, we present the synthesis, characterization and magnetic separation of magnetic polyorganosiloxane nanoparticles. Magnetic iron oxide nanoparticles with average particle radii of 3.2 nm had been synthesized by a simple coprecipitation process of iron(II) and iron(III) salt in basic solution. Afterwards, the particles were successfully incorporated into a polyorganosiloxane network via a polycondensation reaction of trimethoxymethylsilane (T), diethoxydimethylsilane (D) and the functional monomer (chloromethylphenyl)trimethoxysilane (ClBz-T) in aqueous dispersion. A core–shell system was chosen to increase the flexibility of the system concerning size, composition and functional…
Topologically Controlled Inter-Polyelectrolyte Complexes between Molecular Bottlebrushes and Dendrimers
The complexation of a cylindrical polyelectrolyte−brush-surfactant complex (PMMPSS−C12) and an oppositely charged generation-5 PAMAM dendrimer (G5-PAMAM) in methanol (MeOH) leads to kinetically con...
