“…The optical clarity is one of the defining features of nanocomposites over conventional composites. Nanocomposite methodology has been utilized to control the optical properties of polymer-based materials such as refractive index (RI), [5][6][7][8][9][10][11] temperature dependence of RI 8 or birefringence. 12 We have previously reported the synthesis of transparent nanocomposites based on sulfonic-acid-modified poly(bisphenol A carbonate) and TiO 2 or ZrO 2 nanoparticles.…”

This paper presents a successful synthesis of transparent organic-inorganic nanocomposites from poly(arylene ether ketone) (PAEK)-based matrix polymer and BaTiO 3 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. The structure of phosphonic-acid-modified PAEK polymer was studied by gel permeation chromatography, 31 P nuclear magnetic resonance spectroscopy and X-ray fluorescence spectroscopy. Thermal properties of nanocomposites were studied by thermogravimetry and differential scanning calorimetry. Optical clarity of nanocomposites was evaluated by a hazemeter and regular transmittance spectroscopy. Dispersion of nanoparticles was also demonstrated by transmission electron microscopic observation. Fourier transform infrared analysis was carried out to investigate the interaction between the polymer matrix and nanoparticles. Refractive indices of the obtained transparent nanocomposites, which contain up to 44.1 wt% of nanoparticles, were measured. A high refractive index of 1.72 at 589 nm was achieved.

“…Heating or dilution of such particles results either in flocculation, precipitation or formation of an elastic gel. Titanium dioxide based sols and gels in which the size of the nanoclusters is made much smaller than the wavelength of visible light are the characteristics of a good dispersion [91].…”

Abstract:Metal containing polymers are of great interest as they have proven to be the most promising materials for applications such as microelectronics, holography and magnetic recording of information. Metal containing polymers also provide an alternative to even the specialty glass materials conventionally used for optical applications. Metals such as barium, lead and lanthanum have been used to improve the optical properties such as refractive index and mechanical properties such as hardness of optical plastics. The metal-containing optical plastic materials with improved refractive index of as much as 1.60 along with the Abbe number of more than 30 have been successfully designed using these metals by the authors of this paper. To further increase the refractive index without any drop in Abbe number and to improve the hardness of the polymer matrix, titanium would be the most promising metal. Incorporation of titanium in plastic matrices to form homogeneous and optically clear compositions is a challenging task. This paper reviews the state-ofthe-art by which titanium can be dispersed in polymer matrices to form metal containing composites as optical plastics.

“…Although most ceramer materials were based on either TEOS or TMOS, titanium isopropoxide and zirconium isopropoxide were also used as the inorganic phase with PDMS or PTMO as the organic component forming mixed metal hybrid materials (18,28,32,33,34). The subsequent materials were found to have some microphase separation between the inorganic and organic phases.…”
