A new method for fabricating fibrous mesostructured silica on a glass substrate using rubbing‐treated polyimide film is described. Both continuous films (see background of the cover) and fibers with preferred mesochannel orientation can be formed by controlling the reaction rates. Self‐supported fiber‐like silica (see Figure and foreground of the cover) is seen to have smooth surfaces without branching or connecting.
