AFM images with section analysis (a’–c’) of monolayer Langmuir films of GO-SH spread on pure water surface (a, d), DA subphase without UV light (b, e), and with UV light by interfacial thiol-ene photopolymerization (c, f). The transferred surface pressures are 5 mN/m for images (ac) and 15 mN/m for images (df)
