Solvent-regulated ordering in block copolymers

Studies of the structural polymorphism exhibited by block copolymers in the presence of selective solvents are relatively recent, but very promising i n terms of fundamental understanding and practical applications. Highlighti ng recent advances, this review progresses from 'dry' ordered copolymers to solvated ordered (gel-like) copolymers and lastly to solvated disordered ( but focally organized) copolymers. Organic- and aqueous-solvent-based syste ms are concurrently examined to cross-fertilize polymer and colloid science .
