Abstract
A metal-inside-fiber-composite including a biopolymer based fiber having a fiber wall and a void space. The fiber wall envelops the void space such that the void space forms a continuous void space inside and along the fiber. A metal microstructure makes the metal-inside-fiber-composite electrically conductive. A method for producing a metal-and-fiber-omposite, in particular a metal-inside-fiber composite, is also provided.
Claims8
A metal-inside-fiber-composite, comprising:
- a biopolymer based fiber having a fiber wall and a void space, wherein the fiber wall envelops the void space such that the void space is formed as a continuous void space inside and along the fiber;
- a metal microstructure,
- wherein the metal microstructure
- is a microstructure of an elemental metal,
- fills and extends through and along the continuous void space such that the fiber wall forms a protective layer around the metal microstructure,
- includes metal particles
- that are crystalline,
- has an average particle size of at least 80 nm,
- that are interconnected to form the metal microstructure,
- is included in the metal-inside-fiber-composite by at least 60 weight percent of a total weight of the metal-inside-fiber-composite, and
- is electrically conductive to make the metal-inside-fiber-composite electrically conductive.
