  • Aqueous based process to fabricate nanostructured block copolymer films
    Patent number: 9221994
    Abstract: The present invention provides a method to transfer block copolymers from water immiscible organic phase to aqueous phase using a phase transfer agent. At higher concentrations, micellar networks of the block copolymers were obtained in the aqueous solution that can be coated onto a variety of substrates. Block copolymer films showed very good antifouling properties. The phase transferred block copolymers can be used to synthesize encapsulated nanoparticle aggregates for biodiagnostic imaging applications. The phase transferred block copolymer micelles can be used to encapsulate active compounds. The invention has applications in drug delivery, crop protection, and medical device coating.
