A
smart multifunctional surface of conductive plastics with a superhydrphobic surface having porous micro- and nano-
structures can potentially be very useful in many applicatioins of electrostatic dissipation (ESD), electromagnetic
interference (EMI) shielding, and in transparent film heaters with self-cleaning properties. Here, we demonstrate a facile and
rapid method for fabricating superhydrophobic conductive films from transparent conductive films with silver nanowires
(AgNWs) and single-walled carbon nanotubes (SWCNTs) on polycarbonate (PC). This process involves the swelling of the PC
surface in a dispersion of multi-walled CNTs (MWCNTs) in methly ethyl ketone (MEK), followed by coaqulation in isopropy
alcohol (IPA, nonsolvent for PC). During swelling, the AgNWs and SWCNTsmigrated into the plastic, and after that, the swollen
PC chains were crystallized in IPA. Notably, by adding MWCNTs in MEK, the crystallization of PC chains was accelerated,
and the rapid increase in the eletrical resistivity of the films was minized by reducing the formation of microstructures.
Crystallization of the AgNW/SWCNT electrode onto PC and the incorporation of MWCNTs during crystallization provided a
flexible superhydrophobic heater for use as a self-cleaning surface. Our results provide a very easy way to fabricate a conductive
and superhydrophobic polymer surfaces with lotus-like bionic nanostuctures.
