The test results indicate that, under the circumstance of the same mass ratio of EMs/SiO<sub>2</sub>, when the content of PU is relatively low, there is essentially no SiO<sub>2</sub> attached to the surface of EMs; when the content of PU is relatively high, a raspberry-like structure is observed. Furthermore, the influence of different EMs/SiO<sub>2</sub> mass ratios on the wettability of the composite microspheres was examined.
