Effect of crystallization of the polyhedral oligomeric silsesquioxane block on self-assembly in hybrid organic-inorganic block copolymers with salt

[EN] We present a DSC and X-ray scattering study investigating the effect of polyhedral oligomeric silsesquioxane (POSS) block crystallinity on the self-assembly of a poly(acryloisobutyl polyhedral oligomeric silsesquioxane)- b -poly(ethylene oxide)- b -poly(acryloisobutyl polyhedral oligomeric sils...

Semicrystalline polymer/salt mixtures favor morphologies with flat interfaces ( i.e ., lamellae) despite the asymmetric nature of the copolymers; PEO/salt volume fractions range from 0 to 0.85.
