Traditional
deicing methods are increasingly insufficient
for modern
technologies like 5G infrastructure, photovoltaic systems, nearspace
aerocraft, and terrestrial observatories. To address the challenge
of combining anti-icing efficiency with operational performance, an
innovative, spectrally selective, photo/electrothermic, ice-phobic
film was prepared through a cost-effective mist deposition method.
By manipulating the diameter ratio and density of nanowires, the local
density of free electrons within this film is controlled to precisely
dictate the position and intensity of surface plasmon resonance to
achieve spectrally selective photo/electrothermal conversion. Additionally,
the synthesized hydrophobic N-Boroxine-PDMS/SiO2 layer
improves thermal stability and accelerates the deicing process. It
achieves rapid deicing within 86 s under photothermal conditions and
65 s with Joule heating while maintaining high optical transmittance.
The film improves the operational efficiency and thermal safety of
equipment while preserving aesthetics and stability, thereby underscoring
its broad suitability for advanced outdoor installations in cold environments.
