Tricontinuous morphology of triblock copolymers of the ABC type

摘要: A complicated three-dimensional equilibrium morphology, named an ordered tricontinous double-diamond (OTDD) structure, similar to the bicontinous structure for diblock copolymers was found microphase-separated of poly(isoprene-b-2-vinylpyridine). When contnets both end-block polymers are equal, this occurs from 0.48 0.66 volume fractions middle-block polymer, i.e., polystyrene. The TEM data at two different directions, i.e. [111] and [001] directions in good agreement with corresponding images formed by assuming OTDD proposed
