제목 Self-Assembled Morphologies of Polystyrene-b-Poly(1,4-butadiene) Confined in Cone-Shaped Templates: Effect of Confinement Geometries
초록 we demonstrated the self-assembled morphologies of polystyrene-b-poly(1,4-butadiene) (PS-b-PB) confined in conical templates. Based on experimental observation, we concluded that three thermodynamic factors work competitively in the conical confinement system; the interfacial energy of air- polymer, the entropic penalty at the vertices, and the surface energy of the AAO wall. To systematically examine the effect of three competing factors, two additional templates with different bottom geometries (truncated conical and cylindrical templates) were fabricated to control the vertex curvature of conical pores. In an attempt to identify the experimental observation more thoroughly, simulated annealing studies of diblock copolymers along with 3D imaging by TEM tomography were also performed.
