Nano‐engineering of ceramic materials is investigated using block copolymers obtained from poly(isoprene‐ b ‐ethyleneoxide). The dimensions of these “hairy”, nano‐sized products can be tuned by adding varying amounts of two metal alkoxides to give rise to objects of different shapes. The Figure shows a TEM image of cylindrical aluminosilicate coated with a thin layer of block copolymer.
