Interconnected Crosslinked Carbon Nanotubes as Blackbody Emissive and Transmissive Films

Abstract

This study invistagats the applications of interconnected crosslinked carbon nanotubes (iCLCNT) films on silicon substrate to offer efficient infrared (IR) emission as black body behavior for applications such as IR sensors. iCL-CNT exhibits remarkable optical and thermal properties, including low reflectance and high transmission in the visible and near-infrared spectrum. The deposition of iCL-CNT films on the substrate is achieved using Atmospheric Pressure Chemical Vapor Deposition (APCVD) techniques, with focus on their utility as blackbody emissive and transmissive materials. iCL-CNT films are investigated as heated resistors integrated onto silicon micromachined diaphragms and beams, known for their low thermal mass and high thermal conduction. This integration transforms them into high-speed infrared emitters, can be used in non-dispersive gas sensing technology and infrared surfaces in imaging systems, particularly infrared bolometers.
