Honeycomb composite films were prepared by breath figure method via a straightforward, one-step process by doping complex containing Eu or Sn into polystyrene-b-poly (acrylic acid) solution. Several key influencing factors, such as the concentration of the block polymer solution, the relative humidity of the environment and the amount of complexes, were investigated to control micropore size and tune film surface properties. The characteristics of the composite films were studied by scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray diffraction (XRD), ultraviolet and emission spectra. Results indicate that composite films containing Eu have excellent optical performance, and micro-patterned bowl-like SnO2 microparticles could be fabricated from composite films containing Sn after being calcined at 600 °C for 5 h. This general approach for the fabrication of honeycomb composite films opens a convenient and effective route to the functional modification of honeycomb films and offers new prospects for the application in miniaturized sensors, micro-reactor and catalysis.
