Paper Abstract

We reported the "birefringent crystal dopant method" in order to compensate the orientational birefringence of polymers for optical devices. In this method, a birefringent inorganic crystal which has rod-like shape is homogeneously doped into a polymer and it compensates the orientational birefringence of the polymer. Strontium carbonate (SrCO3) was selected for this purpose because it has a large birefringence and a rod-like shape. SrCO3 was synthesized and doped into a poly(MMA/BzMA=78/22 (wt/wt)) (78/22 polymer) film and a cycloolefin polymer film and the films were drawn above glass transition temperature (Tg). The orientational birefringence of the drawn film at a wavelength of 633 nm was compensated and reduced by doping with SrCO3. Furthermore, we analyzed the transparency and thermostability of the films.
