ABSTRACT:
The present invention is an improved material and method for use for providing diffuse reflectivity of light. It has been determined that by employing a polymer having an index of refraction of greater than or equal to 1.42 and a porosity of greater than 10%, improved reflectivity can be achieved over existing reflectant materials having only one of these properties. Suitable materials for use in the present invention include nylon, polyvinylidene (PVDF), and cellulose acetate.
