Query: Thermal Characterization of Absorbing Coatings for Thermal Detectors of
  Radiation by Photopyroelectric Method   By photothermomodulatoin method the comparative study of thermal diffusivity
of absorbing coating for sensitive elements of pyroelectric detectors of
radiation formed from metal dispersion layer blacks, dielectric paint blacks
and carbon nanotubes paint blacks has been performed. Prospects of using carbon
nanotubes based black absorbing coatings for pyroelectric and other thermal
detector application are shown.
