초록 ▼

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.

대표청구항 ▼

A film for controlling the transmission of radiation between surfaces thereof comprising a continuous, solid matrix and disposed in said matrix a set of linear, side-by-side louvers composed of agglomerates of particles of a magnetically-alignable material which differs in permeability relative to the matrix material with respect to at least some selected radiation, wherein said louvers are aligned at a essentially a common angle to the surface of said film and are randomly disposed between said surfaces at a spacing between said louvers of less than 50 microns; and wherein, when radiation impinges on one of said surfaces of said film, said radiation is transmitted through said film so that the angle of maximum transmission through said film is essentially parallel to said common angle of alignment of said louvers and the transmission of radiation is reduced at angles divergent from said common angle.
