“…Factors such as weight fractions of PS and PDMS, , solvents’ selectivity, plasticizers, and topologies of block polymers of PS and PDMS were reported to significantly affect the morphology. , For this study, we focus on the influence of the fluorinated alkyl chain length on the morphology of PS- b -PVMS. As shown in Figure b, the SAXS profile of PS- b -PVMS shows that its morphology matches that of hexagonally packed cylinders (HEX) as the relative values of q / q * are 1, √4, and √7, which are the (1,0), (2,0), and (2,1) peaks of the hexagonal lattice, respectively . For PS- b -P(CF 3 -VMS), its SAXS profile shows more peaks with q / q * of 1, √3, √4, √7, √9, and √13, which are the (1,0), (1,1), (2,0), (2,1), (3,0), and (3,1) peaks of a HEX, respectively .…”
