Electrochemically controlled self-assembly of an organometallic block copolymer.

چکیده
A new means of controlling the order-disorder transition of block copolymers is presented. By applying small electrical potentials (2 V/cm) to disordered solutions of an organometallic block copolymer, oriented ordered grains were obtained near the positive electrode. After reversing the electrical bias on the system, the ordered grains disappeared, and new, oriented, ordered regions were formed at the opposite electrode. Our work establishes the concept of electrochemical self-assembly for controlling order formation in block copolymers.

Aligned sub-10-nm block copolymer patterns templated by post arrays.
Self-assembly of block copolymer films can generate useful periodic nanopatterns, but the self-assembly needs to be templated to impose long-range order and to control pattern registration with other substrate features. We demonstrate here the fabrication of aligned sub-10-nm line width patterns with a controlled orientation by using lithographically formed post arrays as templates for a 16 kg/...
متن کاملControlled supramolecular self-assembly of large nanoparticles in amphiphilic brush block copolymers.
To date the self-assembly of ordered metal nanoparticle (NP)/block copolymer hybrid materials has been limited to NPs with core diameters (D(core)) of less than 10 nm, which represents only a very small fraction of NPs with attractive size-dependent physical properties. Here this limitation has been circumvented using amphiphilic brush block copolymers as templates for the self-assembly of orde...
متن کاملChemically enhancing block copolymers for block-selective synthesis of self-assembled metal oxide nanostructures.
We report chemical modification of self-assembled block copolymer thin films by ultraviolet light that enhances the block-selective affinity of organometallic precursors otherwise lacking preference for either copolymer block. Sequential precursor loading and reaction facilitate formation of zinc oxide, titanium dioxide, and aluminum oxide nanostructures within the polystyrene domains of both l...

A series of thermoresponsive diblock copolymers of poly[2-(dimethylamino)ethyl methacrylate-block-di(ethyleneglycol) methyl ether methacrylate], poly(DMAEMA-b-DEGMA), were synthesized by reversible addition−fragmentation chain transfer (RAFT) polymerizations. The series consist of diblock and quasi diblock copolymers. Sequential monomer addition was used for the quasi diblock copolymer synthesi...
متن کاملThin Film Morphology of Block Copolymer Blends with Tunable Supramolecular Interactions for Lithographic Applications
A modular and hierarchical self-assembly strategy using block copolymer blends (AB/B’C) with tunable supramolecular interactions is reported. By combining supramolecular assembly of hydrogenbonding units with controlled phase separation of diblock copolymers, highly ordered square arrays or hexagonal arrays of cylindrical domains were obtained formixtures of poly(ethylene oxide)-b-poly(styrene-...
