In
this work, a novel anti-smudge coating system was developed
by using hydroxyl-terminated hyperbranched polyester as a coating
precursor, mono-hydroxyl-terminated poly(dimethylsiloxane) (PDMS)
as an anti-smudge agent, and hexamethylene diisocyanate trimer as
a curing agent. The resultant coatings with 0.5 wt % PDMS content
incorporated are highly transparent and liquid repellent. They exhibit
striking repellency against various liquids and display remarkable
self-cleaning performance. Water, hexadecane, salt solution, strong
alkali solution, strong acid solution, pump oil, and crude oil could
slide off the coated surface without leaving any traces, and the dirt
on the coated surface could be readily removed by water or oil. Besides,
these coatings show potential application for anti-fingerprint and
anti-graffiti due to the exceptional repellency of coated surface
against artificial fingerprint liquid, oil-based ink, paint, and water-based
smudge. Furthermore, they also possess superb chemical shielding ability
and thus endow substrates with remarkable protection against exposure
to harsh chemical conditions. Moreover, these coatings are mechanically
robust against extensive abrasion, impact, and bending without compromising
anti-smudge properties, and they also exhibit excellent adhesion to
various substrates. Therefore, these newly developed coatings have
tremendous potential for widespread applications.
