核壳圆柱相是由手性二嵌段共聚物、聚苯乙烯-b-聚(L-丙交酯) (PS-PLLA) 与富含 PLLA 的级分的自组装获得的。聚合物链自组装后，螺旋微域的滚动形成核-壳圆柱体微结构（见图）。然后将微结构水解得到聚合物纳米管，在药物输送和纳米反应器方面具有潜在的应用。
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.
