Fig. 5: Surface composition and morphology of CD/PDMS@Ms.

a Schematic illustration of CD/PDMS PR linkage modes on membrane surface. b Relative fluorescence intensities of γ-CD/PDMS@M surfaces after grafting PPRs for different durations and capping with FITC for 2 h. SEM images showing surfaces of c BM, d PDMS@M, and e β-CD/PDMS@M-0.13. f XPS full spectrum of γ-CD/PDMS@M-0.27. Surface molecular coverage of g β-CD/PDMS@Ms and h γ-CD/PDMS@Ms.
