Nanoporous Materials from Block Copolymer Precursors
Block copolymers constitute a fascinating set of self-assembled materials exhibiting compositional heterogeneities on the nanometer length scale. While traditionally employed as thermoplastic elastomers, asphalt modifiers, and adhesives, the potential of self-assembled block copolymers for nanotechnological applications has been realized in the past decade and many examples have now appeared in...
متن کاملNanoporous block copolymer films using highly selective solvents and non-solvent extraction.
Nanoporous block copolymer thin films are fabricated by selective solvent swelling of the majority phase and subsequent rapid extraction with a miscible non-solvent (water). Selection of the initial solvent provides a facile route to tune the porosity of the films. Poly(butylnorbornene)-block-poly(hydroxyhexafluoroisopropyl norbornene) (BuHFA) is used to generate these porous thin films due to ...
متن کاملHydrazone self-crosslinking of multiphase elastin-like block copolymer networks.
Biosynthetic strategies for the production of recombinant elastin-like protein (ELP) triblock copolymers have resulted in elastomeric protein hydrogels, formed through rapid physical crosslinking upon warming of concentrated solutions. However, the strength of physically crosslinked networks can be limited, and options for non-toxic chemical crosslinking of these networks are not optimal. In th...
متن کاملStability of Order in Solvent-Annealed Block Copolymer Thin Films
One way to produce high order in a block copolymer thin film is by solution casting a thin film and slowly evaporating the solvent in a sealed vessel. Such a solvent-annealing process is a versatile method to produce a highly ordered thin film of a block copolymer. However, the ordered structure of the film degrades over time when stored under ambient conditions. Remarkably, this aging process ...
متن کاملArbitrary lattice symmetries via block copolymer nanomeshes
Self-assembly of block copolymers is a powerful motif for spontaneously forming well-defined nanostructures over macroscopic areas. Yet, the inherent energy minimization criteria of self-assembly give rise to a limited library of structures; diblock copolymers naturally form spheres on a cubic lattice, hexagonally packed cylinders and alternating lamellae. Here, we demonstrate multicomponent na...
