Nano material adsorption steel fiber as well as preparation method and application thereof

The invention provides a nano material adsorption steel fiber as well as a preparation method and application thereof, and relates to the technical field of composite materials. The nano material adsorption steel fiber provided by the invention comprises a steel fiber and a nano material coating the surface of the steel fiber. The steel fiber and the nano material are connected through a silane coupling agent. The nano material is tightly adsorbed on the surface of the steel fiber by using the silane coupling agent, and chemical bonds are generated between functional groups (carboxyl and hydroxyl) attached to the nano material and calcium silicate hydrate in a cement matrix, so that the chemical bonding force of a steel fiber-matrix interface can be improved, and the interface performance is greatly improved. Compared with the prior art, the nano material adsorption steel fiber has the advantages that the chemical bonding force of the steel fiber-matrix interface is enhanced from the nanoscale, and the effect
