Abstract

This work describes the possibility of obtaining latexes derived from hydrophobic modified magnetite nanoparticles (MNPs). The hydrophobic modification was achieved by functionalizing Fe3O4 particles with different monofunctional alkoxysilanes (methyl, octyl, octadecyl and phenyl). Polymerizations were performed through ultrasonic initiated miniemulsion in the presence of sodium dodecyl sulfate (SDS). The hydrophobic ferrite was dispersed in monomer (styrene) with hexadecane and decaethylene glycol oleyl ether (Brij 96 V). The resulted new materials were analyzed by DLS, FT-IR, SEM and TGA. The data show the influence of the hydrocarbon chain length of the alkoxysilanes on the final magnetic hybrids.
