The present invention provides an anisotropic, thermal conductive, electromagnetic interference (EMI) shielding composite including a plurality of aligned polymer nanofibers to form a polymer mat or scaffold having a first and second planes of orientation of the polymer nanofibers. The first plane of orientation of the polymer nanofibers has a thermal conductivity substantially the same as or similar to that of the second plane, and the thermal conductivity of the first or second plane of orientation of the polymer nanofibers is at least 2-fold of that of a third plane of orientation of the polymer nanofibers which is about 90 degrees out of the first and second planes of orientation of the polymer nanofibers, respectively, while the electrical resistance of each of the first and second planes is at least 3 orders lower than that of the third plane. A method for preparing the present composite is also provided.

A thermal camouflage garment containing at least two zones, each zone containing a thermal camouflage fabric. The camouflage fabrics each contain a printed layer. In at least 90% of the wavelengths between 400-700 nm at least one of the first, second, and third color deltas are less than about 10 percentage points, and wherein at 1 μm and 2 μm and the average over 3-5 μm, average over 8-12 μm the first, at least one of the first, second, and third color deltas are greater than about 15 percentage points. The first zone makes up at least about 10% of the outer surface area of the thermal camouflage garment and the second zone makes up at least about 10% of the outer surface area of the thermal camouflage garment.

The present invention relates to a method of manufacturing a high tenacity yarn and a high tenacity yarn manufactured thereby. More particularly, the present invention relates to: a method of manufacturing a high tenacity yarn, the method including coating a yarn made of at least one of nylon and polyester to obtain a coated yarn, wherein the coating material contains 3 to 35 parts by weight of a reinforcing agent composed of a mineral material per 100 parts by weight of a coating liquid containing polyurethane; and a high tenacity yarn manufactured thereby. Therefore, it is possible to manufacture a yarn having high tenacity and improved processability by processing a nylon or polyester yarn having a relatively low tenacity as compared with a high modulus polyethylene (HMPE) yarn by use of a yarn coating technique, and further to reduce production cost.

A fiber comprises a bulk material comprising: one or more of carbon, silicon, boron, silicon carbide, and boron nitride; and a metal or metal alloy whose affinity for oxygen is greater than that of the bulk material. At least a first portion of the metal or metal alloy is present at the entrance to grain boundaries at the surface of the fiber and within the fiber to a depth of at least 1 micron from the fiber surface. A method of improving a fiber comprises heating a fiber in an inert atmosphere to 900-1300 C for sufficient time to allow at least some of a metal or metal alloy, placed on the fiber, to diffuse and/or flow into and along grain boundaries to a depth of at least 1 micron. The metal or metal alloy has a greater affinity for oxygen than that of the fiber bulk material.

Described herein are methods for forming resistive heaters and force sensing elements on a flexible substrate, and devices that include these elements to provide a force responsive conductive heater, such as a seat heater in a vehicle. The methods include printing a conductive ink on a flexible substrate that is heated to 30° C. to 90° C. before and/or during the printing process and curing the substrate to produce a conductive pattern thereon. The conductive inks generally include a particle-free metal-complex composition formulated from at least one metal complex and a solvent, and optionally, a conductive filler material.
