This disclosure relates to an article (e.g., a vapor-permeable, substantially water-impermeable multilayer article) that includes a nonwoven substrate and a film supported by the nonwoven substrate. The film includes a polyolefin, a nanoclay, and a pore-forming filler.

A laminate film manufacturing method is capable of preventing thickness unevenness of a cured layer and preventing wrinkling of the entire laminate film. A laminate film is manufactured by applying a coating solution including an active radiation curable resin to a surface of a first film that is continuously transported in an application part to form a coated film in a lamination part, laminating a second film that is continuously transported on the coated film to sandwich the coated film between the first film and the second film, and in a state in which the coated film is sandwiched between the first film and the second film, winding the first film around a backup roller and irradiating the coated film with infrared rays from an ultraviolet irradiation device while continuously transporting the first film to cure the coated film in a curing part so as to form a cured layer.

The invention relates to a method for producing a master batch comprising between 0.01 and 50 wt. % of carbonaceous nanofillers and at least one sulphurated material such as elemental sulphur by melt compounding, and to the master batch thus produced and the different uses thereof. The invention also relates to a solid composition comprising carbonaceous nanofillers dispersed in a sulphurated material.

A fastener for improved electrical contact with a composite structure and improved distribution of electric current to the composite structure. The fastener includes an elongated shaft having a first end with a head portion, a second end with a threaded portion, and a shaft body therebetween. At least one feed channel extends from an opening at the threaded portion, through the shaft body, and terminates proximal to the head portion. The shaft body radially expands upon pressure injection of a resin filler into the feed channel, when the fastener is installed in a corresponding fastener hole formed in the composite structure. Upon radially expanding, the outer surface of the shaft body makes contact with an inner hole surface of the corresponding fastener hole, resulting in the fastener providing electrical contact with the composite structure and providing distribution of electric current.

A composite film having a high dielectric permittivity engineered particles dispersed in a high breakdown strength polymer material to achieve high energy density.

In an embodiment, the present disclosure pertains to a method of direct ink writing (DIW). In general, the method includes extruding a resin from a print head, applying radio frequency (RF) heating to the resin, and inducing partial curing of the extruded resin layer-by-layer to thereby form a self-supporting structure. In an additional embodiment, the present disclosure pertains to a system for DIW. In some embodiments, the system includes a print head operable to extrude a resin from a nozzle and an RF applicator.

A method of using high push force to fabricate a composite material containing carbon material comprises steps placing a substrate in a carbon material-containing dispersion including a carbon material, and letting one surface of the substrate contact the carbon material-containing dispersion; and providing a high push force range between 300 G and 3000 G to the carbon material-containing dispersion to push the carbon material-containing dispersion and make the carbon material enter the substrate to form a composite material containing the carbon material.

The present invention relates to a flexible and transparent polyimide laminate and manufacturing method thereof. The flexible and transparent polyimide laminate comprises a conductive layer, an adhesive layer and a polyimide substrate. The conductive layer includes a plurality of metal nanowires, and is attached on the polyimide substrate by the adhesive layer. The adhesive layer is an insoluble polyimide film and is polymerized by aromatic dianhydride and one of the following monomer: alicyclic diamines, fluorine-containing diamines, and the combination thereof.

An article includes a body and at least one 3D-printable conductive composite segment in mechanical communication with the body. The body includes a first material and the at least one conductive composite segment includes a matrix material, a plurality of carbon nanotubes, and conductive additives. The conductive additives include a plurality of metallic particulates, a plurality of graphitic particles or a combination thereof.

This disclosure describes a polymer composition that includes a polymer and functionalized carbon nanotubes, and systems and method of formation thereof. The polymer composition includes functionalized carbon nanotubes and one or more polymers. Parts formed from the polymer composition have improved sloughing properties as compared to parts formed from compositions including conventional carbon nanotubes. Additionally, parts formed herein have lower liquid particle count values as compared to parts formed from compositions including conventional carbon nanotubes.
