Synthesis and characterization of high refractive index nanoparticle/poly(arylene ether ketone) nanocomposites

Transparent organic–inorganic nanocomposites were successfully synthesized from poly(arylene ether ketone)-based matrix polymer and BaTiO3 nanoparticles. The dispersibility of nanoparticles was significantly improved by both the introduction of phosphonic acid moiety into the polymer chain and the organic modification of the nanoparticle surface. Refractive index of the obtained transparent nanocomposite, which contains 44 wt% of BaTiO3, increased to 1.72 @ 589 nm.
