Tunable Reflectance by Doped Conjugated Polymers
ABSTRACT
The future demands on the Defense Forces are, among others, a greater flexibility to function in widely different and
unforeseen environments. Moreover there must be a readiness to approach new sensor threats in wavelength bands, where
efficient management is lacking at present. These two aspects are of concern to the project ‘Adaptable Signature Materials,’
with the keywords tunability and multispectrality. In recent years, conjugated polymers have become increasingly interesting,
from a varied point of view. The potential ability of tuning electrical and optical properties is of highest interest. Application
examples are resistive sheets and flexible/soft displays. Concerning resistive sheets in different kinds of radar absorbers for
military use, the polymer can be applied onto different types of carrier material as textiles and plastic foil. Concerning
flexible/soft displays, the polymer can either be a part of the bearing structure in order to make it flexible and/or it can be used
as an active electro-optical material. This is a very active research field with many different civilian applications. There are
hardly any reports on tunability of conjugated polymers within the IR-region.
