In-situ polymerized siloxane urea enhanced graphene-based super-fast, durable, all-weather elec-photo-thermal anti-/de-icing coating
Ice accumulation is a pervasive natural phenomenon that exerts a severe and catastrophic impact on a broad range of social systems. Previous investigations on anti-/de-icing techniques have primarily focused on mild laboratory conditions, which have limited practical applicability due to their short...

Ice accumulation is a pervasive natural phenomenon that exerts a severe and catastrophic impact on a broad range of social systems. Previous investigations on anti-/de-icing techniques have primarily focused on mild laboratory conditions, which have limited practical applicability due to their short service life. Consequently, there is an urgent demand for the development of durable anti-/de-icing technologies capable of withstanding complex environmental conditions. In this research endeavour, we have successfully formulated a hydrophobic coating based on graphene. To circumvent the challenges associated with environmentally unfriendly organic solvents, we utilized a graphene water slurry as the foundational material and subsequently incorporated a poly (vinyl alcohol)-water solution. The resulting solution was subjected to in situ polymerization of a siloxane urea crosslinked polymer, yielding the desired coating solution. Following a solution spraying and drying process, the ultimate product obtained was the hydrophobic conductive graphene (HCG) siloxane Coating. The HCG siloxane Coating exhibits a conductivity of 66 S/m, enabling it to melt ice droplets within a mere 10 s, whereas conventional coatings require 20–500 s for the same task.
