Abstract

A method developed for optical polymers by doping with silica particles that were optically isotropic was analyzed. The orientation function of polymer main chains confirmed that particles reduced the birefringence of a polymer by the orientation-inhibition effect. The analysis showed that the doping of the particles reduced the orientational birefringence of polycarbonate (PC) and poly(methylmethacrylates) (PMMA) films regardless of the sign and magnitude of their birefringence. A spectrophotometer was used for measuring transmittance of undrawn PC based films. The analysis results show that about 15% of the birefringence of heat-drawn PC and PMMA films was reduced at a wavelength of 590 nm by doping with 1 wt% of the particles.
