摘要:The preparation of monodispersed TiO 2 nanocrystals with nanocrystal size between 1-30 nm is described herein. These TiO 2 nanocrystals are used to prepare dispersions into solvents, formulation into monomers, oligomers, and polymers, and nanocomposites from the resulting formulations. Dispersions of nanocrystals can be formed in various solvents at high loading, high transmittance, and low viscosity. Formulations incorporating these nanocrystals and a matrix material are highly stable, where the resulting nanocomposites have high refractive index and are optically transparent in the visible wavelengths, with very little or no scattering.

摘要:Preparation of capped metal oxide nanocrystals comprising a metal oxide shell that are photocatalytically and thermally stable and their dispersions in monomers, oligomers, and polymers, as well as the resulting formulations and nanocomposite films. These nanocrystals are highly monodisperse with nanocrystal size between 3-100 n. Resultant formulations incorporating these nanocrystals and a matrix material are highly stable and result in nanocomposites that have high refractive index, are highly transparent, have minimal to no change in absorption upon thermal or UV processing and are optically transparent in the visible wavelengths with very little or no scattering.

摘要:Provided is a semi-aromatic polyamide, comprising, on the basis of the molar content of all repeating units, the following repeating units: 46‑54 mol% of 10T unit derived from 1,10‑diaminodecane and terephthalic acid, 46-54 mol% derived from one or more monomers in diacid Y containing 4-36 carbon atoms, and XY unit consisting of one or more monomers in diamine X containing 4-36 carbon atoms; the 10T unit and XY unit in the semi-aromatic polyamide chain segment are arranged in an alternating order ... 10TXY10TXY10TXY 10TXY10TXY ...; the semi-aromatic polyamide at least contains three monomers. In the semi-aromatic polyamide prepared by means of the special preparation method, 10T and XY units are arranged alternately, and in comparison with ordinary random copolymerized semi-aromatic polyamides, it has higher crystallinity and a higher melting point, and the water absorption rate is low.

摘要:The synthesis of barium titanate nanocrystals, the capping of barium titanate nanocrystals to disperse into solvents, including polar and nonpolar solvents, polyalphaolefins, lubricants, oils, and greases, monomers, oligomers, and polymers including acrylics, epoxies, siloxanes, and the preparation of nanocomposites of barium titanate in combination with these monomers, oligomers, and polymers. The barium titanate nanocrystals are monodispersed with sizes between 1-200 nm and have an ideal barium to titanium ratio. The nanocrystals of size greater than 80 nanometer can possess high dielectric constants and can be ideal candidates of ceramic conductors and RF sensors. Nanocomposites resulting from the barium titanate nanocrystals of size less than 40 nanometer in combination with the monomers, oligomers, and polymers can possess high refractive index, high transparency, low absorbance, and minimal change when exposed to heat or UV light.
