Silicone Based Nanocomposites Including Inorganic Nanoparticles and Their Methods of Manufacture and Use

Rensselaer researchers have developed a thermodynamically stable dispersion technology resulting in thick, transparent, high refractive index silicone nanocomposites that increase the light efficiency of LEDs and improve the emitted light color quality. The nanocomposites could also be processed as transparent bulk material with high filler loading, which is essential for optical, magnetic and biomedical applications.

Nanoparticles with Multiple Attached Polymer Assemblies and Use Thereof in Polymer Composites

This technology relates to synthesizing nanoparticles with multiple polymer assemblies attached. In one example, a first anchoring compound is attached to a nanoparticle, and a first group of monomers are polymerized on the first anchoring compound to form a first polymeric chain covalently bonded to the nanoparticle via the first anchoring compound. In another example, a first polymeric chain can be attached to the nanoparticle, where the first polymeric chain has been polymerized prior to attachment to the nanoparticle.

Nanocomposites with Controlled Electrical Properties

Polymers play an important role in electrical insulating and field grading technology because of their high electrical strength, ease of fabrication, low cost and simple maintenance. Conventionally, additives have been mixed into polymer matrices to improve their resistance to degradation, to modify mechanical and thermomechanical properties, and to improve electrical properties such as high-field stability. However, concentional additives have a negative effect on electrical properties.

Tubular Microstructures Via Controlled Nanoparticle Assembly

There is an increasing interest in using nanoparticles as building blocks for well-defined structures that have practical applications owing to the various novel properties of nanoparticles. However, their assembly is a challenging task. Methods based on surface functionalization, andor template patterning have been used for this purpose, but both of these processes can be rather complicated. Thus, there is a continuing need for a simple method for synthesizing high aspect ratio microstructures constituted of nanoparticle building blocks.


The continued development of optical communications requires fast information processing. Therefore, ultrafast, all-optical systems and switches for basic processing at both ends of an optical transmission line are replacing electronic systems. However, there are speed and fabrication limits on present all-optical switches imposed by the properties of the materials presently used. This technology provides an improved ultrafast high sensitivity all-optical switch made from a single-walled carbon nanotube.
