We successfully prepared a dynamically oleophobic epoxy coating with low contact angle hysteresis (≤ 5.2°) for different low surface-tension liquids. Due to significant enrichment of covalently bonded polydimethylsiloxane (PDMS) at the coating surface, the obtained coating displays remarkable repellency against various low surface-tension liquids, including hexadecane, dodecane, decane, and soybean oil, as well as anti-smudge property and strong interfacial adhesion towards various substrates. Moreover, these excellent surface/interfacial properties have demonstrated to be very robust after being subjected to different environments (low pH, high pH, heating, and UV exposure). This type of coating may find promising applications in a broad range of fields where oil repellency is desired.
