Abstract:
1. A multi-walled carbon nanotube device for measurement comprising: a housing for a sensor, said housing with improved broadband absorption properties having at least one surface adjacent a receptor for said sensor, wherein said at least one surface is coated with adhesion improved coated multi-walled carbon nanotubes, whereby stray light scattering into said receptor is minimized; adhesion and catalyst refining layers to optimize a multi-walled carbon nanotube growth process; multi walled carbon nanotubes adhered on titanium and stainless steel, while maintaining broadband absorption; alumina as an excellent adhesion layer for nanotubes grown on titanium, stainless steel and silicon wherein the alumina adhesion layer is greater than 60 nanometers thick to optimize performance by including a 10 minute annealing means immediately after growth at 750 C to 950 C, allowing better anchoring of nanotubes into an alumina layer as determined by measuring hemispherical reflectance on a silicon and titanium sample before and after testing; and an electron beam evaporation layer applied immediately prior to the deposition of an iron catalyst layer of a thickness of iron of 1 to 2 nanometers while maintaining vacuum to provide a robust durable coating.
