Self-Cleaning Flexible Infrared Nanosensor Based on Carbon

Highly flexible, robust, and sensitive infrared nanosensors were fabricated based on carbon nanoparticles that were synthesized through a simple and low-cost flame method. The infrared nanosensor devices showed sharp infrared photoresponse with a response time of ∼68 ms andamaximum photocurrent changeof ∼52.9%.Thedevicesshowedasuperhydrophobic property with a contact angle larger than 150� and a sliding angle of ∼4� . The mechanism for the enhanced infrared photoresponse from carbon nanoparticles is discussed.
