A well-defined D/A lamellar structure of the P3HT-b-AcMal7:AcMal7-C61 blend with sub-10 nm domain features is achieved upon thermal annealing. The AcMal7-C61 molecules are localized in the phase-separated AcMal7 nanodomains without causing the formation of fullerene crystals while maintaining the lamellar morphology up to 1:0.5 (D:A) blending ratio. The cross-sectional TEM observation and GISAXS measurement reveals that the P3HT-b-AcMal7 tends to spontaneously organize into lamellar structures oriented perpendicular to the film surface at the air/film interface while the domain orientation at the bottom interface depends on the nature of the substrate. ? 2020 Elsevier Ltd |
