Embodiment 1
[0021] will PS- b -PDMAEMA was dissolved in carbon disulfide to obtain a homogeneous PS of 1 mg / mL- b -PDMAEMA solution, PS- b -The molar percentage of styrene units in PDMAEMA is 90%, and 0.1 mL of PS- b - Spread the PDMAEMA solution evenly on the ice surface, quickly place it in an environment with a relative humidity of 80%, and take it out after the solvent evaporates to obtain a through-type PS- b - PDMAEMA honeycomb-shaped ordered porous membrane with a pore size of 3.9 μm; the silicon wafers were placed in acetone solution and deionized water for 30 minutes, and then dried with nitrogen gas, and the above silicon wafers were sputtered by radio frequency magnetron sputtering technology. A zinc oxide seed layer is formed on the surface, the specific conditions are: growth temperature 350°C, sputtering pressure 1.0 Pa, gas atmosphere 80 sccm Ar : 5 sccm O 2 , sputtering time 1 hour, sputtering power 100 W. Covering the through-type PS- b -PDMAEMA honeycomb ordered por...
