Tubular Nanostructures from Degradable Core-Shell Cylinder Microstructures in Chiral Diblock Copolymers

A core–shell cylinder phase is obtained from the self assembly of chiral diblock copolymers, polystyrene‐b‐poly(L‐lactide) (PS–PLLA) with PLLA‐rich fractions. After the self‐assembly of the polymer chains, scrolling of the helical microdomains results in core–shell cylinder microstructures (see figu...

Description
Summary:A core–shell cylinder phase is obtained from the self assembly of chiral diblock copolymers, polystyrene‐b‐poly(L‐lactide) (PS–PLLA) with PLLA‐rich fractions. After the self‐assembly of the polymer chains, scrolling of the helical microdomains results in core–shell cylinder microstructures (see figure). The microstructures are then hydrolyzed to give polymeric nanotubes with potential applications in drug delivery and as nanoreactors.
