Magnetically oriented ice-template method for conductive and wear-resistant composites

Abstract

A disclosed electric-conduction wear-resistance composite material molded by using a magnetic-orienting ice-templating method comprises 1-3 parts by mass of a carbon tube, 1 part by mass of a binder, 1 part by mass of a dispersant and 96-98 parts by mass of a resin material, and has an ordered fiber wall porous structure formed by directional alignment of a carbon nanotube. The invention also discloses a method for the composite material. Magnetic orientation is employed aiming at the carbon nanotube which is uniformly plated with nickel and is subjected to heat treatment, also an ice-templating method is employed for fixing the orientation and assisting to correct the orientation direction and further for preparing the carbon nanotube ordered frame, and the construction manner is efficient, simple in technological principle, low in price and suitable for large-scale production.

Description

technical field

[0001] The invention relates to the technical field of carbon nanomaterial processing technology and application, in particular to a conductive and wear-resistant composite material shaped by magnetic orientation ice template method. Background technique

[0002] In recent years, in the research field of carbon nanotubes as a reinforcing phase, researchers have encountered a large number of research difficulties, such as the poor dispersion of carbon nanotubes in the polymer matrix due to agglomeration, and the free carbon nanotubes Dispersion is even dispersed in the matrix after a certain degree of ordering, but due to the performance limitations of the matrix itself, the excellent performance of carbon nanotubes cannot be fully exerted. At present, referring to the reports at home and abroad, the relevant research is still in the preliminary stage on which distribution method of carbon nanotubes in the matrix can maximize their functional properties.
