Abstract

Very low molecular weight polyethylene (average MW 700 g/mole) magnetic nanocomposite particles were synthesized by nonsolvent and temperature induced crystallization along with ultrasonication. The particles are further coated with poly dl-lactic acid to functionalize the polyethylene particles for biomedical applications. A solvent-nonsolvent emulsion was made with polyethylene and surface modified iron oxide and was raised to very high temperature followed by rapid cooling. Decalin and octamethylcyclotetrasiloxane (OMCTS) were used as solvent and tetraglyme as nonsolvent. The synthesized particles were found to have two different types of morphology. Particles sizes can be varied depending on the choice of solvent, polymer concentration and amplitude of ultrasonication. The composite particles were characterized by scanning transmission electron microscopy. Magnetic properties of the composite particles were also studied.
