| Abstract | In this Article,we addressed a facilemethod for the fabrication of porous polyimide filmwith an ordered surface based onthe solvent-evaporation-assisted in situ self-assembly of polyamic acid (PAA, precursor of polyimide) and silica micro-spheres during vacuum-drying of PAA/silica colloid solution. Hydroxyl groups on the surface of silica microspheres havestrong hydrogen-bondingwith PAAchains, which improve the dispersion of silicamicrospheres in PAA/DMFsolution andfurther help the self-assembly of PAA/silica colloid solution via solvent evaporation. The approach is simple, neither thepreparation of special template nor complex preparation process and precise control over condition is necessary.Furthermore, the method could be employed for mass production of ordered porous polyimide films, and by changingthe content and size of silicamicrospheres, the pore size and porous structure of the porous polyimide films could be tunable.The wettability behavior of the as-prepared porous polyimide films is also studied; the ordered surface topography of theporous polyimide films could change the wettability from hydrophilicity to hydrophobicity. |
