Oxidatively stable magnetic metal nanoparticles prepared with copolymers containing phthalonitrile moieties, and polymer-metal complexes and their conversion to oxidatively-stable metal nanoparticles

摘要

Oxidatively-stable, magnetic cobalt nanoparticles and other Group VIII nanoparticles are provided, and production methods. Poly(styrene-b-4-vinylphenoxyphthalonitrile) (a novel composition) or random graft copolymers containing phthalonitrile groups in the backbone are examples of compositions that may be complexed with cobalt or other Group VIII metals.
