Abstract:
The invention relates to an aqueous sizing composition for reinforcing charges, preferably glass fibers, comprising a silane coupling agent, an epoxy film forming polymer comprising 2-8 reactive epoxy groups per chain and compatible with thermoplastic polyester matrix resin selected from PET and PBT, and a hypophosphite in an amount of 5 to 30 w% of the composition, preferably 7 to 25 w%, more preferably 10 to 20 w% and most preferably 12 to 18 w% of the composition. A thermoplastic polyester resin reinforced with glass fibers coated with a sizing composition of the invention shows improved resistance to staining and improved tensile elongation at break. The sizing composition further improves processability of the sized fibres.

Abstract:
The present disclosure provides methods and compositions for an organic nanofiber- based heterojunction material, comprising nano fibers of an acceptor molecule, the nano fibers coated with a donor molecule, where the acceptor molecule contains a group and the donor molecule contains a companion group, wherein the group and companion group enables strong binding between the acceptor molecule and donor molecule, the strong binding providing for efficient forward electron transfer between the acceptor molecule and donor molecule, and wherein the group and companion group minimize charge carrier recombination between the acceptor molecule and the donor molecule.
Abstract:
Polymer compositions, methods of making polymer compositions, structures having the polymer composition covalently bonded to the surface of the structure, methods of attaching the polymer to the surface of the structure, methods of decreasing the amount of microorganisms formed on a structure, and the like, are disclosed.
Abstract:
Among other things, a communication line is attached along a target surface of a building by laying out the line from a tool. An outer surface of the line is in a temporarily tacky condition as the line is laid out along the surface. The line is in the temporarily tacky condition based at least in part on an adhesive component having been pre-applied to the outer surface of the line. The line becomes non-tacky after it has been attached.

Abstract:
Methods of protecting a person, animal or other object from hot high heat capacity and/or hot corrosive materials, such as hot molten metal, hot oily liquids (e.g., heating oil), hot gels, hot solids, hot sparks, and hot acids. The methods include protecting a person, animal or other object from hot molten metals, such as liquid metal zinc heated to a temperature of about 950 °F (510 °C) or greater, hot molten aluminum heated to a temperature of about 1150 0F (620 °C) or greater, burning phosphorus at temperature of about 1550 °F (843 °C) or greater, hot solid iron having a temperature of about 500 °F (260 °C) or greater, hot heating oil having a temperature of about 500 °F (260 °C) or greater, and hot hydrochloric acid having a temperature of about 300 °F (150 °C) or greater. The ability to protect a wearer from heat from hot high heat capacity materials and/or hot corrosive materials is quite different from simply shedding liquids, even flammable liquids, such as gasoline is unexpected.

Abstract:
The present invention relates generally to sizing compositions for fibers used in composite materials. More specifically, this invention relates to siloxane fiber sizing solutions comprising rubbery-polymers and their use in preparing composite materials. Using the sizings of the present invention not only improves the energy absorption of the composite materials made thereof, but also maintains the interfacial strength of composite materials. Particularly, the rubbery-polymers of the present invention are functionalized with chemical groups that react to the fiber surface and/or to the polymeric resin. In addition, because the rubbery-polymer is incorporated as one block of a block copolymer, it advantageously improves both, the interfacial strength and energy absorption.
