Abstract
Oriented conjugated polymer shaped articles can be formed by the process of (a) providing a carrier solution made up of (i) carrier solvent, (ii) nonconjugated flexible chain carrier polymer, and (iii) conjugated polymer or conjugated polymer precursor; (b) forming this carrier solution, before or after gelling the solution and removing solvent from it, thereby yielding a body having a first shape, and (c) anisotropically physically distorting the first shape of the body to yield the desired shaped article formed with an oriented structure in the carrier polymer and in the conjugated polymer. The orientation of the conjugated polymer leads to anisotropic absorption and photoluminescence properties for the shaped article.
Claims11
A process for forming an oriented conjugated polymer-containing shaped article comprising the steps of
- (a) providing a carrier solution comprising (i) carrier solvent, (ii) nonconjugated flexible-chain carrier polymer and (iii) conjugated polymer or conjugated polymer precursor;
- (b) gelling and forming said carrier solution and removing solvent therefrom thereby yielding a body having a first shape;
- and
- (c) anisotropically distorting the first shape of the body to yield the oriented conjugated polymer-containing shaped article characterized by having both nonconjugated flexible chain polymer and conjugated polymer is oriented form and by exhibiting anisotropic absorption and photoluminescence.
