To address issues such as cumbersome preparation processes for conventional superhydrophobic coating，superhydrophobic coating was prepared by using mesoporous silica nanoparticles（MCM-41）as filler and carrier，polydimethylsiloxane（PDMS）as low surface energy modifiers，and epoxy resin and its curing agent as film former. The morphologies，structure，hydrophobicity and adhesion of coating was characterized by FE-SEM，confocal microscope，contact angle meter and tensile testing machine. The influence of MCM-41 modified by PDMS（MCM-41/PDMS）and resin matrix mass ratio on coating performancewere mainly investigated. The results showed that the optimum match of wettability（CA=150°， SA=9°）and adhesion（7. 33 MPa）could be obtained when the content of MCM-41/PDMS was55%. The water contact angle of coating surface remained over 150° after 300 times tape peeling test and 150 cycles abrasion test.
