Fiber Material Having a Manganese Oxide Coating

Abstract

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.

Description

Claims

1. A method for coating a fiber material with manganese oxide, the method comprising: applying a manganese oxide precipitate to the fiber material;drying the manganese oxide precipitate; andoxidizing 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.

2. The method as claimed in claim 1, further comprising applying the manganese oxide precipitate wet-chemically from potassium permanganate and manganese(II) salts.

3. The method as claimed in claim 1, further comprising removing hydroxyl groups from the manganese(IV) oxide layer.

4. A method for producing an antiviral and/or antibacterial fiber material, the method comprising: applying a menganese ozide precipitate to the fiber material;drying the manganese oxide precipitate;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;and applying silver to the fiber material.

5. The method as claimed in claim 4, wherein applying silver comprises: applying a silver nitrate solution; andreducing the silver nitrate solution to form silver using a reducing agent.

6. The method as claimed in claim 4, further comprising drying the fiber material under a protective gas atmosphere.

7. A fiber material having a melting temperature and/or a decomposition temperature below 200° C., also having a manganese oxide coating that has at least 70% by weight, in particular at least 75% by weight, of manganese(IV) oxide, with respect to the manganese oxide coating.

8. The fiber material as claimed in claim 7, wherein the manganese oxide coating has less than 5% by weight of manganese(II) oxide with respect to the manganese oxide coating.

9. The fiber material as claimed in claim 7, further comprising silver.

10. The fiber material as claimed in claim 7, further comprising polymer fibers.
