Abstract

The invention discloses a preparation method of zinc oxide nanowire array/carbon nanofiber composite material, relates to preparation methods of nano composite materials, and aims to solve the problems that existing carbon nanofibers are low in surface area, and the contact area of the carbon nanofibers with solution is limited during application. The preparation method includes the steps of firstly, using an electrospinning method; secondly, using a hydrothermal synthesizing method. The zinc oxide nanowire array/carbon nanofiber composite material is large in surface area, excellent in conductivity, and the like. The preparation method is mainly used for preparing the zinc oxide nanowire array/carbon nanofiber composite material.

Description

technical field [0001] The invention relates to a preparation method of a novel nanocomposite material. Background technique [0002] Carbon nanofibers are fibrous nanocarbon materials rolled from multilayer graphite sheets, which have excellent physical and mechanical properties and chemical stability, such as good electrical and thermal conductivity and excellent mechanical properties. Carbon nanofibers are generally derived from electrospun polymer nanofibers, such as polyacrylonitrile and pitch. Polyacrylonitrile is the main precursor for preparing nano-carbon nanofibers, because the strength and elastic modulus of carbon nanofibers can be flexibly controlled by controlling the later carbonization and stabilization temperature. [0003] Nano-zinc oxide refers to nano-materials with a grain size between 1nm and 100nm. Due to the sharp decrease in grain size, nano-zinc oxide exhibits many special properties that bulk materials do not have, such as non-migration, fluoresce...
