Invention field
The present invention relates to a kind of method for preparing conductive polymers-carbon nano tube compound material.
Background technology
Conductive polymers is owing to having, and density is low, but the diversified molecular designing of structure, electromagnetic parameter can be in harmonious proportion advantages such as unique physics, chemical property and have good development prospect, and caused the extensive attention of scientific circles, in such as these fields of secondary cell, device for non-linear optical, semiconducter device, electrochromic device, transmitter, stealth material and electromagnetic shielding, had a wide range of applications.
In numerous conducting polymer materials, Polythiophene becomes the research focus in conductive polymers field owing to characteristics such as having easy polymerization, Heat stability is good, excellent physical chemistry, better electrochemical performance and environmental stability.The same with other conductive polymers, the specific conductivity of Polythiophene is different with synthetic method and doping condition etc., and electroconductibility can differ greatly, and can be conductor, semi-conductor or isolator.Different is, most conductive polymerss can improve its solvability in solvent after introducing substituting group, but are cost to sacrifice specific conductivity mostly, and Polythiophene is when introducing alkyl on the thiphene ring ring, not only can increase the solvability of thiphene ring, can also guarantee that specific conductivity does not reduce simultaneously.The oxidation potential of thiophene is higher simultaneously, and the oxidation potential of some thiophene derivants is relatively low, so thiophene derivant has also caused people's very big interest.
Carbon nanotube is one of nano material of tool representative, and its particular structure makes it have many good physical and chemical performances.Characteristics such as carbon nanotube has that density is little, intensity is high, heat conduction and conductivity are good, its unique mechanical and electromagnetic property are indicating that it has broad application prospects.For example be made into absorbing material, will have good microwave absorbing rate.
The composite modified research focus that has become present material of carbon nanotube, with carbon nanotube and conductive polymers compound also be the problem that is worth very much research, and obtained certain progress, but the poorly soluble subject matter that remains a needs solution of matrix material.Can improve mechanical property and other performance of conductive polymers behind the formation matrix material; Simultaneously the agglomeration traits of carbon nanotube also is one of problem that limits its application, if carbon nanotube coated with conductive polymers then can prevent the generation of its reunion.
Summary of the invention
Technical problem to be solved by this invention is, at carbon nanotube is a kind of nano material that broad prospect of application is arranged, but the easy reunion of carbon nanotube is not easy the dispersive problem and has limited its application always, and the insoluble problem of most of conduction high polymer-carbon nano tube compound material.
