Formation of a very low-reflectance surface by electrostatic flocking
Abstract
The implantation of carbon pile perpendicular to the substrate, thereby making it possible to form a surface having a very low reflectance owing to the so called light trap effect, where light beams incident of the surface are reflected and attenuated among the fibers no matter at which angle the light beam may incident, are considered. How very low reflectance flocked surfaces were achieved over a wide range of wavelengths from near ultraviolet to the infrared range by optimizing the cut length, heat treatment, and quantity of the carbon pile for lift is described.
