Zinc oxide nanorod modified aramid fiber as well as preparation method and application thereof

The invention provides a zinc oxide nanorod modified aramid fiber as well as a preparation method and application thereof, and belongs to the field of high polymer materials and functional nano materials. According to the preparation method of the zinc oxide nanorod modified aramid fiber provided by the invention, the aramid fiber is subjected to surface carboxylation treatment firstly, and then the'bridge 'effect of the silane coupling agent is exerted by utilizing the bifunctional characteristic of the silane coupling agent, so that one end of the silane coupling agent with alkyl hydroxyl is subjected to chemical bond reaction with carboxyl on the surface of the fiber, and the zinc oxide nanorod modified aramid fiber is obtained. An amino functional group at the other end is connected with zinc oxide, so that the interface bonding strength of the aramid fiber and the nano-zinc oxide is improved. The result of the embodiment shows that the diameter of the zinc oxide nanorod in the zinc oxide nanorod modified
