In this paper, we
have developed a one-step thermal treatment of polydimethylsiloxane
(PDMS) liquid to create transparent super-repellent surface (TSS)
and super-repellent powder. They are super-repellent toward water
and ethylene glycol. During the one-step thermal treatment, PDMS soot
is generated and deposited onto a glass slide (GS) surface to fabricate
the TSS without fluorosilane modification. The facilely obtained TSS
presented superhydrophobicity and self-cleaning property when immersed
into very low surface tension oils such as petroleum ether, hexadecane,
peanut oil, and dodecane. Interestingly, by controlling heating time
and temperature, wettability of the treated GS surface and the remained
white powder can be regulated. The mechanism of tunable wettability
was revealed and analyzed by investigating the variations of surface
morphology and chemical composition. More importantly, TSS was able
to repel highly corrosive aqua regia and saturated NaOH solutions.
TSS maintained excellent superhydrophobicity even after chemical and
mechanical damages. This simple thermal deposition method was also
applicable for other thermally stable substrates to achieve super-repellency,
which are believed to find very promising applications.
