a–c The water contact angle test procedure of the nanofiltration device. d Comparison to the nanofiltration device, the water contact angle of bare glass surface was 36.5o. e Permeation flux of the nanofiltration device compared with reported filtration materials33,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51. UV–vis absorption spectra of f MB, g RR, and h EB solutions before and after filtration through the nanofiltration device and pristine cellulose membrane. i Rejection performance of nanofiltration device and pristine cellulose membrane for dye molecules with different sizes. j Cycling tests of the nanofiltration device for EB filtration. k Nitrogen sorption isotherms of the regenerated mesoporous silica sheets. Inset is the corresponding TEM image.
