A superhydrophobic EP/PDMS nanocomposite coating with high gamma radiation stability
Abstract(#br)The superhydrophobic coatings with high gamma radiation stability were prepared by using epoxy/polydimethylsiloxane (EP/PDMS) resins as the matrix and silica nanoparticles as the fillers. The nanocomposite coatings exhibit superhydrophobicity with a high water contact angle (WCA) of 154° and a low sliding angle of 7°. With the amount of SiO 2 increasing from 0 to 30%, the surface shows the hierarchically structure gradually and its roughness raised from 4\u003cce:hsp sp=\"0.25\"/\u003enm to 278\u003cce:hsp sp=\"0.25\"/\u003enm.
