We report a rapid and reversible morphology control of a polyhedral oligomeric silsesquioxane (POSS) containing block copolymer (PEO-b-PMAPOSS), which composed of poly(ethylene oxide) (PEO) and POSS-containing poly(methacrylate), (PMAPOSS), between ordered arrays of dots and lines for several tens of seconds by combination of thermal annealing and solvent annealing. The reversible morphology change and ordering of phase morphology in a short time are enabled by a distinctive property of PEO-b-PMAPOSS with highly mobility of the chain at the thermal and the solvent annealing states.
