Dispersion experiments. Dispersion behaviors of various HGMP particles in oil–water mixtures: for diesel-water, (a) W-HGMPs, (b) O-HGMPs, (c) and J-HGMPs; for crude oil–water, (d) W-HGMPs, (e) O-HGMPs, (f) and J-HGMPs; and top view, (g) the top view of (d), (h) the top view of (e), (i) and the top view of (f) J-HGMPs; (j) average diameter of oil droplets of Janus HGMPs particles with different concentrations at the interface between diluted crude oil and deionized water (volume ratio of diluted crude oil to deionized water: 1:9); and (k) Interfacial tension of Janus HGMPs particles at different oil–water interfaces (diesel oil deionized water interface and diluted crude oil deionized water interface). The experiment was repeated three times, and the relative experimental error was ± 1%.
