Disclosed are a hydrophobic and oleophobic coating, a preparation method therefor and a product, wherein the hydrophobic and oleophobic coating is formed by the deposition of a perfluoropolyether or perfluoropolyether derivative on the surface of a substrate by means of PECVD, such that the hydrophobic and oleophobic properties of the surface of the substrate are improved by the perfluoropolyether or perfluoropolyether derivative coating. Further disclosed are a hydrophobic and oleophobic coating, a preparation method therefor and a product, wherein the hydrophobic and oleophobic coating comprises: at least a two-layer structure, one of the layers being formed by the plasma chemical vapor deposition of one or more perfluoropolyethers or perfluoropolyether derivatives as raw materials, and the other layer being formed by the plasma chemical vapor deposition of a silane- or siloxane-containing raw material, thereby improving the hydrophobic and oleophobic properties of the surface of a substrate.

Various embodiments of the teachings herein include methods for coating a fiber material with manganese oxide. For example, a method may include: applying a manganese oxide precipitate to the fiber material; drying the manganese oxide precipitate; and oxidizing the manganese oxide precipitate using an oxygen plasma at a temperature below 200° C. forming a manganese(IV) oxide layer having at least 70% by weight with respect to the manganese oxide precipitate.

Electret webs include a thermoplastic resin and a charge-enhancing additive. The charge-enhancing additive is a substituted- or unsubstituted benzoate salt. The substituted benzoate salts are substituted by a hydroxyl group. The substituted-benzoate salt may have a divalent metal countercation.

A plasma device applies cold atmospheric plasma to a surface to be treated, in particular to textiles, leather and/or plastic fibers. An actuator activates a plasma source, provided that a distance between the plasma source and the surface to be treated is less than a predetermined distance. The actuator has an adjustable and pre-loaded actuator element with at least one activation element and has a recording apparatus that records the position of the actuator element at least when the distance between the plasma source and the surface to be treated is less than the predetermined distance. The plasma device makes it possible to avoid risks owing to incorrect operation by the client and to avoid emissions, since the plasma source is activated only when the distance from the item to be treated (e.g., clothing to be cleaned) is less than the predetermined threshold distance.

Provided herein is a metal coated textile substrate prepared by an ultrasonic irradiation deposition process involving depositing a first plurality of metal nanoparticles on a textile substrate by a first ultrasonic irradiation deposition process thereby forming a metal seeded textile substrate; and depositing a second plurality of metal nanoparticles on the metal seeded textile substrate by a second ultrasonic irradiation deposition process thereby forming the metal coated textile substrate.

A device and a method of flattening recycled carbon fiber material are provided. A main body is provided with two flat plates at an upper and a lower positions corresponding to each other and an ultrasonic unit is disposed on each of the flat plates. While in use, recycled carbon fiber material is placed at the lower flat plate and then at least one ultrasonic probe of the ultrasonic unit is driven to work and vibrate the recycled carbon fiber material into a flat and thin state. After the flattened recycled carbon fiber material being pressurized to form products required, the product has flat and smooth surfaces with special textures. A thickness of the product can be controlled and the product can be thinned according to users' needs, without surface treatment such as grinding, polishing, etc. Thereby production cost is reduced and yield rate of the products is improved.
