Multifunctional laser-ablated lubricant-infused slippery film with self-sensing and anti-icing/deicing properties

•A multifunctional laser-ablated lubricant-infused slippery film is prepared using a combination of CO2 laser-induced graphene and lubricant oil infused processes.•It exhibits the characteristics of low ice adhesion strength, outstanding anti-icing/photothermal deicing performance.•Owing to the temperature sensing ability of the LIG conductive network, it can monitor the whole process of icing and deicing in real time.•It has important application prospects in ice monitoring and removing. In this paper, we have developed a multifunctional laser-ablated lubricant-infused slippery film (MLLSF) by combining laser-induced graphene and lubricant-infused processes. Due to its lubricant-infused slippery surface characteristics, the MLLSF can decrease the ice adhesion strength to 7 kPa and prolong the ice time to 5 min at -20 °C. At the same time, benefitting from the outstanding photothermal effect of the laser-induced graphene conductive network, the surface temperature can rapidly rise from -20 °C to 45.6 °C in 60 s under 808-NIL illumination, thereby effectively melting the ice. More importantly, owing to the temperature sensing ability of the LIG conductive network, the prepared MLLSF can monitor the whole process of droplet icing and deicing process in real time. Therefore, this MLLSF with self-sensing, anti-icing and deicing properties has important practical values in monitoring and removing ice. [Display omitted]
