Morphology of Block Copolymer Polymer Blends

50% SBM/50% SB blend superlattice, M cylinders (white), surrounded by four B cylinders (dark) attached to it, S forms the matrix (gray) cyUnder at cylinder morphology  

80%SBM/20%SBblencL mixed superlattice at inter faces between parallel S (gray) and M (white) lamellae B, cylinders (dark) are located cylinders at lamellar interface  

S = PS, B = PB, T = poly(tert-butyl methacrylate) periodic lamellar superlattice with sequence of colors gray (S) black (B) white (T) gray artifact at grain boundary with broken dark B lamellae  

SBS Star-block copolymer / PS blend (80/20), solution-cast film
