Interpretive Summary: The application of “intelligent” fabrics is an active pursuit by the military. Fabrics which may store and transmit data are currently heavily funded areas of research. Producers of military uniforms are asked to incorporate secondary functions into each uniform. It is desired that uniforms act not only to protect the soldier from the elements, but also to take a more active roll in sensing and communication. This technology will rely on materials which can be woven into the fabric or applied as a specialized coating. It is in this area that conducting and semiconducting coatings applied to cotton may act as “wiring” for the next generation of military uniforms.
Technical Abstract: A series of siloxane copolymers containing pendent phosphonate groups have been prepared and their electrochemical impedance tested. Condensation reactions between methoxy groups of the mononomers produced crosslinked films which were clear, colorless, and stable to air and moisture. The polymers were doped with varying amounts of either lithium perchlorate or N-lithiotrifluoromethanesulfonimide and their conductivity determined.
