Patterned optical anisotropy in woven conjugated polymer systems
Artikel i vetenskaplig tidskrift, 2012
Weaving of highly oriented conjugated polymer/polyethylene tapes is demonstrated to permit the
generation of concealed patterns that can be detected under appropriate polarized light
illumination. This is achieved by exploiting the fact that the amount of transmitted light varies with
the superposition sequence of semi-transparent objects that feature a high degree of linear
birefringence as well as linear dichroism. An analysis based on M€uller calculus provides a
theoretical description of the observed optical behavior.
