CONTROLLED SIZE MACROMOLECULAR-MAGNETITE COMPLEXES

摘要

Polymeric magnetite stabilizers containing PCL tail blocks and a carboxylic acid containing PVMS central anchor block were synthesized. Nano-magnetite was formed in the 10-20 nm size range. Magnetite was stabilized with the triblock copolymer forming nano-magnetite dispersions. Stabilizers with shorter PCL tail blocks were capable of stabilizing larger amounts of magnetite, creating dispersions that display higher magnetic responses.
