Ordered porous films have received great interest in the past few years because of their potential application in functional membrane, biological materials and medical science. Even though lots of lithographic techniques were used to prepare ordered porous materials, the expensive cost limited its wide range of application. However, the so-called breath figures approach which had the inexpensive and simple process attracted researchers' attention. To prepare the porous films with excellent thermal stability and corrosion resistance, urushiol metal polymers, which contained the superior heat resistance and chemical resistance, were employed in the work. High ordered porous films were successfully prepared via the breath figures method making use of the urushiol copper polymers (UCP). The effects of solvents, the relative humidity and the moist airflow speed on the morphology of the porous films were investigated, and then the product was characterized by SEM and IR. The results showed that the honeycomb-structure porous films could be obtained by taking carbon disulfide as solvent in the static state (the relative humidity: 95%) or in the gas flow rate of 400 mL/min (the relative humidity: 85%). And they had good hydrophobicity, excellent chemical resistance and thermal stability. Furthermore, the pore size was about 1.5 μm under 95% relative humidity and 0.85 μm under 85% relative humidity.
