Method of fabricating conductive thin film

A method of fabricating a conductive thin film includes the following steps: forming a polymer fiber made of a polymer and a metal precursor distributed in a surface layer near the surface of the polymer fiber; and applying a plasma treatment on the polymer fiber to concurrently etch the polymer and reduce the metal precursor in the surface layer of the polymer fiber. When the plasma treatment is completed, a metal membrane is formed on the surface of the polymer fiber.

LASER-BONDED NON-WOVEN TEXTILE
20240368812 · 2024-11-07 ·

A nonwoven textile can be treated with a laser to construct bonding structures between fibers of the nonwoven textile. In examples, the nonwoven textile can have fibers including a material that absorbs electromagnetic radiation emitted by a laser. In addition, based on absorbing the electromagnetic radiation, the fibers can soften, and the softened portions of the fibers can contact one or more other fibers of the nonwoven textile. When the softened portions re-solidify (e.g., after removal of the electromagnetic radiation), the re-solidified portions of the fiber can at least partially encapsulate the other fiber(s) to form the bonding structure between the re-solidified portions and the other fiber(s). In some examples, the bonding structure can reduce the likelihood of the fibers that are associated with the bonding structure from migrating through a face of the nonwoven textile and forming pills.

Bonded Insulation Product Batt From Spent Carpet And Waste
20180094763 · 2018-04-05 ·

A thermal insulation batt is created from recycled carpet fibers and fire resistant cotton shoddy bonded by staples of bi-component fiber having a polyester core and low melting polymeric sheath. The low melting polymeric sheath melts at a temperature well below the melting or degradation temperature of any of the carpet fibers from the recycled carpets. Since the sheath has a small thickness, the amount of melt created is small and bonding occurs only between the bi-component staple fiber and adjacent carpet fiber or fire resistant cotton shoddy without melt overflow. The rigidized thermal insulation batt can be used in a building between studs and may be used in an automobile door for sound proofing. This product is particularly well suited for use as acoustic and thermal insulation in buildings as non-load bearing partitions in interior offices of commercial buildings. This bonded low density composite fibrous structure has fire retarding constituents incorporated within the batt to retard propagation of building fire. These stated uses are non-limiting; and other uses are contemplated, including automobile interior structures.

Mounting mat including inorganic nanoparticles and method for making the same

The present invention relates to a mounting mat for mounting a pollution control device in a catalytic converter, the mounting mat comprising a non-woven mat of inorganic fibers having distributed therein inorganic particles having an average diameter of 1 nm to 100 nm and wherein the mounting mat is free of organic binder or contains organic binder in an amount of not more than 5% by weight, based on the total weight of the mounting mat. The invention further relates to a pollution control device including the mounting mat and to a method of making the mounting mat.
