TEM images of HMOCs obtained after hypercrosslinking of SiO2@PS core-shell precursors with different DVB content and etching SiO2 core.
(a) 0.5% - HMOCs, (b) 1% - HMOCs, (c) 2.5% - HMOCs, (d) 5% - HMOCs, (e) 10% - HMOCs, (f) 15% - HMOCs.Styrene is 10 ml with 130 nm hollow cavities. TEM images of HMOCs with different thickness of the shell by varying the dose of styrene in SiO2@PS core-shell precursors, (g) 10% - HMOCs - 2.5 ml, (h) 10% - HMOCs - 5 ml, (i) 10% - HMOCs -10 ml, (j) 10% - HMOCs - 15 ml with 130 nm hollow cavities. TEM image of HMOCs with 200 nm hollow cavities. (k) 10% - HMOCs - 5 ml–200 nm, (l) 10% - HMOCs - 10 ml–200 nm. The mass of SiO2 nanoparticles is 1.2 g. The scale is 200 nm.
