HYBRID NANOPARTICLES WITH CONTROLLED MORPHOLOGY AND THEIR USE IN THERMOPLASTIC POLYMER MATRIX NANOCOMPOSITES

摘要

Nanoparticles with controlled and highly monodispersed morphology made using a modified Stöber sol-gel process. The hybrid silica nanoparticles with controlled morphology having uniform size, shape or both, and contain an aliphatic amine of 2-20 carbon atom, or an alkoxide compound selected from the group consisting of siliceous alkoxide (R′_(X)—Si—(OR″)_(4-X)), and/or titanium alkoxide (R′_(X)—Ti—(OR″)_(4-X)) and/or zirconium alkoxide (R′_(X)—Zr—(OR″)_(4-X)), wherein R′ group can be equal or different that R″, and the R group in the chemical structure are between 1 to 18 carbon atoms, and mixtures thereof, having from one to four alkoxy groups, or a combination of said aliphatic amine and said alkoxide compound.
