Abstract

In this study, we focus on refractive-index and Abbe-number improvements to optical polyesters. First, we modify polymers by introducing sulfonyl groups and removing phenyl groups in the monomer structure. In this manner, new polymers with Abbe numbers higher than 40 are synthesized. To further increase the refractive index and Abbe number, the polymers are hybridized with well-dispersed alumina nanoparticles (NPs). The prepared polymer/alumina nanocomposites have a high refractive index and Abbe number; (nD = 1.580 and VD = 55) and (nD = 1.631 and VD = 53), which easily exceeds the empirical "limiting line" of conventional optical polymers.
