Abstract

The invention discloses a carbon nano tube / titanium dioxide / polysulfonamide nano ternary composite material and a preparation method thereof. The carbon nano tube / titanium dioxide / polysulfonamide nano composite material is prepared by a solution mixing method in physical mixing technology, and then is formed into composite fiber or composite membrane. By adopting the ultrasonic mixing technology of the invention, the nano particles can be evenly distributed in polysulfonamide substrate in nanometer level, and further can be perfectly combined with the toughness and processability of organic high-molecular polymer due to the rigidity, high temperature size stability and heat resistance of the nano particles, in particular to the perfect electric conductivity of the carbon nano tube and theremarkable ultraviolet ray resistance, in this way, the polysulfonamide material is endued with the perfect property which cannot be reached by the traditional method. The method of the invention is simple and convenient in technology, high in operability and low in cost.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a carbon nanotube / titanium dioxide / polysulfone amide nanometer ternary composite material and a preparation method thereof. Background technique [0002] As a new type of textile material, polysulfoneamide fiber has excellent heat resistance, thermal stability and flame retardancy, etc. It is used in the aerospace field, protection under high temperature working environment and other civil fields with flame retardancy requirements. It has important uses in national defense, military affairs and modern industry. However, conventional polysulfoneamide fibers have problems such as high volume specific resistance and poor UV resistance, which seriously affect their subsequent processing and application in other functional industrial fields.
