Composite reinforcer sheathed with a layer of polymer that is self-adhesive to rubber

A composite reinforcer that can adhere directly to a diene rubber matrix is usable as a reinforcing element for a pneumatic tire. The composite reinforcer includes at least one reinforcing thread, such as a carbon steel cord. Covering each thread individually or several threads collectively is a layer of a thermoplastic polymer composition. The thermoplastic polymer composition includes at least one thermoplastic polymer have a glass transition temperature that is positive, a poly(p-phenylene ether) (PPE), and a functionalized unsaturated thermoplastic styrene (TPS) elastomer having a glass transition temperature that is negative. The TPS elastomer includes a functional group selected from: an epoxide group, a carboxyl group, an acid anhydride group, and an ester group. A process for manufacturing such a composite reinforcer is presented, as well as a process for producing a rubber article, especially a pneumatic tire, incorporating such a composite reinforcer.

Enhanced performance of mineral based aqueous barrier coatings

A method for preparing an aqueous based coating system, and coating systems made thereby, for coating onto paper and/or paperboard for providing barrier to liquid, moisture vapor, oil and grease including a pigment and a polymer emulsion system or natural based binding system. One alternative of the method includes surface treating a pigment to form a pigment system and mixing a polymer emulsion system or natural based binding system with the pigment system. Another alternative of the method includes mixing a pigment and polymer emulsion system or natural based binding system and hydrophobizing the polymer emulsion system or natural based binding system by adding silanes, siloxanes, siloxane/silicone resin blends, or their carbon based analogs.

Carbon black for waterborne coatings

An aqueous carbon black millbase, an aqueous carbon black liquid coating, and a method of making the millbase and liquid coating are provided.

Highly thermal conductive nanocomposites

Disclosed are methods for forming carbon-based fillers as may be utilized in forming highly thermal conductive nanocomposite materials. Formation methods include treatment of an expanded graphite with an alcohol/water mixture followed by further exfoliation of the graphite to form extremely thin carbon nanosheets that are on the order of between about 2 and about 10 nanometers in thickness. Disclosed carbon nanosheets can be functionalized and/or can be incorporated in nanocomposites with extremely high thermal conductivities. Disclosed methods and materials can prove highly valuable in many technological applications including, for instance, in formation of heat management materials for protective clothing and as may be useful in space exploration or in others that require efficient yet light-weight and flexible thermal management solutions.
