Abstract
The present invention provides an optical polarizer and a method of fabricating such an optical polarizer. The optical polarizer includes a support member and an optical polarizing film supported by the support member. The optical polarizing film includes a number of carbon nanotubes. The carbon nanotubes are compactly aligned with and parallel to each other. The optical polarizing film constructed with carbon nanotubes can work at high-temperature and in moist environments and has excellent abrasion resistance properties. Furthermore, a diameter of a carbon nanotube is only about 0.4˜30 nm, so the polarizing ability of the optical polarizer can extend into the UV region. The degree of polarization in the UV region is 0.92.
