Investigation of open-air laser-induced chemical vapor deposition of carbon on moving optical fibers

Continuous High-Yield Production of Vertically Aligned Carbon Nanotubes on 2D and 3D Substrates

“…Nevertheless, these studies only demonstrated batch processing, where CNTs were grown on a static substrate placed inside a CVD furnace. A continuous process for VACNT manufacturing requires a mechanism to continuously introduce a catalyst-coated substrate, pass the substrate through a processing environment, and then remove the finished product. , A few studies of CNT growth on moving substrates have been made in open , and closed reactors. In an open-air reactor configuration, a quartz substrate was moved relative to a laser spot that acted as the heater .…”
