Abstract


In this paper, three urushiol-metal polymers were synthesized. The microporous films of three urushiol-metal polymers have been successfully fabricated by breath figure method in the moisture atmosphere. Furthermore, several influencing factors on the formation of urushiol-metal polymers microporous films and the different morphologies, such as the concentration of the polymer solution, the moist airflow speed, the relative humidity in the atmosphere and the substrates were investigated. The microsphere patterns were prepared by reverse breath figure method.Urushiol Zirconium Polymer (UZP) was successfully synthesized by solution polymerization from Urushiol and ZrCl4. The obtained polymer was characterized by FT-IR, TG, XPS and UV-Vis. The result showed that UZP had excellent properties. Later, UZP microporous films have been successfully fabricated by Breath Figure method. The conditions of the exposed atmosphere play an important role on the surface morphology of the UZP microporous film during the formation. From SEM, the pore sizes of UFP films increased with increasing of the RH of the atmosphere, the speed of the moisture airflow. The relatively uniform pores of UZP films can be formed under the concentration of 10.0 mg/mL, the RH of 85%, and the speed of the moisture airflow of 400 L/min. The UZP microporous films are hydrophobic and can retain the original morphology after being immerged in 10% hydrochloric acid solution or 10% NaOH for 12 h. This microporous films with dynamically controlled pore size, hydrophobic surface and good chemical resistance, are expected to play an important role in the future applications. The UZP microsphere patterns were successfully fabricated by reverse breath figure method. From the SEM results, the relatively uniform sphere of UZP films could be formed under the concentration of 5.0 mg/mL, the reaction time of 2 h and the spreading volume of 10.0μL. The patterns of the microspheres become more uniform as the concentration of the UZP/CHCl3 decreased.Urushiol Ferrous Polymer (UFP) microporous films have been successfully fabricated by Breath Figure method. From SEM, the pore sizes of UFP films increased with increasing of the speed of the moisture airflow and the concentration of the solution. The relatively uniform pores of UFP films can be formed under the concentration of 50.0 mg/mL, the RH of 85%, and the speed of the moisture airflow of 400 mL/min. This microporous films with dynamically controlled pore size, hydrophobic surface and good chemical resistance, are expected to play an important role in the future applications. The UFP microsphere patterns were successfully fabricated by reverse breath figure method. From the SEM results, the relatively uniform sphere of UFP films could be formed under the concentration of 50.0 mg/mL, the reaction time of 15 h, and the spreading volume of 10.0μL. The patterns of the macrospheres become more uniform as the concentration of the UFP/CH2C12 increased.High ordered porous films were successfully prepared via the breath figure method from 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 UCP porous films was successively immersed in 10% HCl and 10% NaOH for 4 h, the other was placed in the oven at 150℃for 1 h. The results showed that the honeycomb-structure porous films could be obtained by carbon disulfide as solvent in the static state (the relative humidity:95%) or in the moist airflow speed of 400 mL/min (the relative humidity:85%). Furthermore, this microporous films with dynamically controlled pore size, hydrophobic surface and good chemical resistance, are expected to play an important role in the future applications.
