An amphiphilic triblock copolymer has been used as a structure-directing agent to produce a mesoporous ordered thin film by a spinning technique. The triblock copolymers consisting of polyethylene oxide (PEO) and polypropylene oxide (PPO) possess amphiphilic properties in a solution and forms self-assembled ordered structures. F108 copolymer, which has the highest value of R (R is the monomer number ratio of ethylene oxide to propylene oxide) among used copolymers, was used to make a highly ordered cubic structure thin film.
