In this research, a simple flame treatment method was explored to generate micro−/nano-structures on polydimethylsiloxane (PDMS) micro-patterns. Ethanol soaked paper wipes were used as a flame source at a temperature of 700 ± 20 °C. After flame-treated for 30 s, a unique flower petal nano-structures were formed on all surface types: flat PDMS (PDMS-FLT) and PDMS with square pillar pattern (PDMS-PIL) and PDMS with rectangular ridge patterns (PDMS-REC). The flower petal nano-structures, which acts like a re-entrant micro−/nano-structure, was formed by an aggregation of organosilicon compounds in PDMS matrix. Averaged values of surface roughness of the PDMS-FLT, the PDMS-REC and the PDMS-PIL have increased to 298.9, 662.3, and 731.1 nm, respectively. The PDMS-PIL surface that was flame-treated for 30 s exhibited superhydrophobic and superoleophobic properties with water and ethylene glycol contact angle greater than 150°. Those properties led to liquid droplets spreading out instantly and rolling off very fast. Therefore, the flame treatment is expected to be one promising method to fabricate biomimetic surface with good reproducibility and stability on a large-scale antifouling surface for various applications.
