A morphology transition from spherical mesopores to worm-shaped mesopores within titania–polystyrene-b-poly(ethylene oxide) (titania–PS-b-PEO) composite thin films is achieved by varying the sol–gel reaction time from 40 min to 48 h with 0.25 wt.-% PS-b-PEO and fixed solution composition, as confirmed by imaging and scattering techniques.
