ABSTRACT:
Radiation transmission control films comprising closely spaced agglomerates of small particles, e.g. in linear, side-by-side louvers, in a solid matrix where the agglomerates exhibit different radiation permeability than the matrix. Methods of making such films include magnetically aligning particles into louvers in an uncured matrix then curing the matrix to provide louvered film. Such films are useful to control the transmission of light, other electromagnetic radiation and particle radiation.
