Disclosed herein are nanocomposite materials, devices thereof and methods thereof with a dielectric constant and corona resistance while having an increased or substantially maintained energy density, breakdown strength and/or dissipation factor relative to the polymer.

Polymer nanocomposites for electronic applications

Reinforced polyimide compositions that include a reinforcing filler and a polyamide flow promoter improve flow promotion while maintaining other mechanical, thermal, flame and/or electrical properties of the compositions. The compositions may include an inorganic or organic reinforcing filler, a polyimide resin such as polyetherimide or polyamideimide and a small amount of an aromatic or aliphatic polyamide as the flow promoter. The resulting compositions may be used in thinner-wall applications while still retaining the advantageous physical properties of reinforced polyimide compositions not having the flow promoter. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

Flow in reinforced polyimide compositions

The present invention provides a polymeric composition including a blend of at least two different polymers selected from the group consisting of polystyrene, polycarbonate, polyetherimide, polyolefin, polysulphone, polyethersulphone, polyacetal, nylon, polyester, polyphenylene sulphide, polyphenylene oxide and polyetheretherketone and at least one elastomer having a tensile modulus less than about 50,000 p.s.i. Alternatively or additionally, the elastomer may be functionalized to graft with at least one of the polymers. The present invention also provides a method of making a tribological wear system by melt-mixing the polymeric composition to improve the wear resistance of a polymeric composite whose surface bears against another surface, thereby causing friction and wear of the polymeric composite.

Toughened polymeric compositions and methods of improving friction and

The present invention provides a method of improving the wear resistance of a polymeric composite comprising a polyamide and a polypropylene. The polymeric composite is a component of a tribological wear system in which a surface of the polymeric composite bears against another surface causing friction and wear of the polymeric composite. By the present method, at least one crystalline polymer is functionalized to graft with at least one of the polyamide and the polypropylene to form the composite.
