Electrically Conductive Adhesive Film
An electrically conductive adhesive film includes an adhesive layer having opposing first and second major surfaces spaced apart a distance T in a thickness direction of the adhesive layer, where T≥20 microns, and a plurality of electrically conductive particles dispersed in the adhesive layer between the first and second major surfaces. For at least 90% of the electrically conductive particles in the plurality of electrically conductive particles, the electrically conductive particles have a particle diameter D50 greater thank T/4 and a maximum size of the electrically conductive particles is less than T.
Protection film
Provided is a protection film including a plurality of layers, including a first carrier layer having a plurality of electrically conductive fibers; a metal layer; and a second carrier layer having a plurality of electrically conductive fibers. Each of the first and second carrier layers has a void volume at least partially filled with a hardenable composition. Also provided is a protection film including a first metal layer, a carrier layer, and a second metal layer, in which the carrier layer is at least partially filled with a hardenable composition. These films can provide lightning strike protection with suitable tensile, rigidity and tack properties for automatic tape layup and automatic fiber placement applications.
Formulation for a stable electrically conductive polymer
The present invention is an electrically conductive polymer that is stable with respect to both time and environmental conditions. Most electrically conductive polymers have bulk resistance that varies (increases) over time. The current electrically conductive polymers also vary when they are exposed to harsh environments. The time and environmental variability is attributable to both the type of fiber and the type of coating used. The present invention uses stainless steel fibers that have an outer most coating that is one of tin, tin-lead, tin-silver, tin-palladium, tin-silver-palladium, and silver-palladium. The coating comprises 5%-40%, by weight, of the coating fiber. The coated fiber comprises 25%-35%, by weight, of the electrically conductive polymer. The bulk polymer is at least one of polypropylene (“PP”), polycarbonate (“PC”), acrylonitrile butadiene styrene (“ABS”), polyethylene (“PE”), polyether ether ketone (“PEEK”), and polyethylene terephthalate (“PET”).

Method for radiation shielding
A composition and method for spray-applying a two-part, self-setting composition containing a dopant that provides a hazard shielding component and is particularly adapted for delivering the components of the composition at a temperature that promotes their spray application as well as a self-setting reaction. The method includes selecting a self-setting compound that is adapted for curing in place once applied, the self-setting compound including at least one dopant material; and applying the compound to a hazard to be encapsulated such as a radiological, lead, asbestos, or PCB. Alternately, a self-curing compound includes a multi-part compound which, upon a mixing of the parts, chemically reacts and cures, and at least one dopant material dispersed into at least one of the parts, wherein the dopant material is selected for providing radiation shielding upon application of the compound.
Fiber Reinforced Flexible Foams
A flexible foam composition comprising a flexible foam structure comprising a plurality of struts, and a plurality of fibers, where a majority of the fibers are associated with the struts. The fibers may be thermally conductive fibers. The fibers include, but are not necessarily limited to, homopolymer and/or copolymer fibers having a glass transition temperature (Tg) of −50° C. (−58° F.) or greater, carbon fibers, animal-based fibers, plant-based fibers, metal fibers, and combinations thereof.

The flexible foam composition may be polyurethane foam, latex foam, polyether polyurethane foam, viscoelastic foam, high resilient foam, polyester polyurethane foam, foamed polyethylene, foamed polypropylene, expanded polystyrene, foamed silicone, melamine foam, among others.
ANISOTROPIC CONDUCTIVE FILM AND METHOD FOR MANUFACTURING SAME, AND BONDING STRUCTURE AND ULTRASONIC BIOMETRIC IDENTIFICATION APPARATUS
The present invention relates to an anisotropic conductive film and a method for manufacturing same, and a bonding structure and an ultrasonic biometric identification apparatus. The anisotropic conductive film comprises first conductive particles and second conductive particles, wherein the particle size of the first conductive particles is less than the particle size of the second conductive particles, and the ratio of the number of the first conductive particles to the number of the second conductive particles is (3-8):1. The anisotropic conductive film is applicable to pins made of different materials, and is particularly applicable to a bonding structure where a pin made of a relatively hard material and a pin made of a relatively loose material exist at the same time, thereby ensuring that the anisotropic conductive film has a relatively low conduction impedance and excellent conduction stability on both of the two materials.
