Highly Ordered Nanoporous Thin Films by Blending of PSt-b-PMMA Block Copolymers and PEO Additives as Structure Directing Agents
Herein, we present a simple method for producing nanoporous templates with a high degree of lateral ordering by self-assembly of block copolymers. A key feature of this approach is control of the orientation of polymeric microdomains through the use of hydrophilic additives as structure directing agents. Incorporation of hydrophilic poly(ethylene oxide) (PEO) moieties into poly(styrene-b-methyl...

متن کاملDouble-bond-containing polyallene-based triblock copolymers via phenoxyallene and (meth)acrylate
A series of ABA triblock copolymers, consisting of double-bond-containing poly(phenoxyallene) (PPOA), poly(methyl methacrylate) (PMMA), or poly(butyl acrylate) (PBA) segments, were synthesized by sequential free radical polymerization and atom transfer radical polymerization (ATRP). A new bifunctional initiator bearing azo and halogen-containing ATRP initiating groups was first prepared followe...
متن کاملPEO-PPO-PEO triblock copolymer in aqueous solution. Micelle formation and crystallization
The phase behavior of poly(ethy1ene oxide) poly(propy1ene oxide) poly(ethy1ene oxide), PEO-PPO-PEO, tri-block copolymers dissolved in water has been studied using small-angle neutron scattering, using a Couette device for shear alignments. The structural properties has been studied as a function of polymer concentration and temperature. At low-temperature and low polymer concentrations the unim...
متن کاملDefect-free nanoporous thin films from ABC triblock copolymers.
The self-assembly of triblock copolymers of poly(ethylene oxide-b-methyl methacrylate-b-styrene) (PEO-b-PMMA-b-PS), where PS is the major component and PMMA and PEO are minor components, provides a robust route to highly ordered, nanoporous arrays with cylindrical pores of 10-15 nm that show promise in block copolymer lithography. These ABC triblock copolymers were synthesized by controlled liv...
