The styrene-acrylate spheres were coated with the TiO2 colloidal particles via electrostatic effect and hydrogen bond interactions with the increase of aging time, thus the film-forming capability of the solution was changed. The poor film-forming capability results in the formation of the porous structure with dense, homogeneous island morphology. Then the TiO2 porous films with dense pores can be obtained after two coating-dissolving cycles.

结果表明，TiO2溶胶与苯丙乳液混合后，陈化时间的延长有利于TiO2胶粒通过静电、氢键作用在苯丙乳液粒子表面形成吸附层，从而改变涂膜液的成膜性，形成较为密集、且均匀分布的岛状多孔结构，在此基础上经两次涂膜，即可获得具有致密孔洞的TiO2多孔薄膜。
