Materials characterization. a Schematic illustration of the in situ wrapping process. TEM images of b CMK-3/S, scale bar: 20 nm, c CMK-3/S@PANS, scale bar: 50 nm and d CMK-3/S@PANS@TPS particles, scale bar: 10 nm. S2p XPS spectra of e CMK-3/S, (f) CMK-3/S@PANS, and g CMK-3/S@PANS@TPS samples. P2p XPS spectra of h CMK-3/S, i CMK-3/S@PANS, and j CMK-3/S@PANS@TPS samples. k TEM image of a CMK-3/S@PANS@TPS particle and the EDX elemental mapping across the multi-layered core–shell composite particle along the dashed line with the arrow pointing in the direction from 0 to 300 nm in the position, scale bar: 100 nm
