Abstract : Design and synthesis of a polymer to selectively absorb infrared energy was studied. A polymer was designed that could be synthesized to incorporate a large number of different polymer groups known to absorb at the desired wavelength bands. Both film and foam specimens were prepared from the polymer, and their absorption spectra confirmed the adequacy of the design. The foamed material appeared more efficient as a masking filter for infrared of relatively short wavelength, and it is postulated that the increase is due, at least in part, to scattering by cell walls.
