In this study, we investigated the influence of TiO 2 content and thickness of polystyrene (PS) template on film‐formation behavior of PS/TiO 2 composites using fluorescence and ultraviolet–visible techniques in conjunction with scanning electron microscopy. Films were prepared by coating PS templates with various layers of TiO 2 using dip‐coating method. The results showed that PS latexes present complete film formation on top surface of composites. After extraction of PS, a well‐defined interconnected porosity were obtained for thin films when TiO 2 content was increased, whereas thick samples did not present any interconnected porous structures above a certain TiO 2 layer.
