Abstract
A process for synthesizing polyphenylamine oligomer end-terminated by phenyl features that the mother body oligoner of polyphenylamine in the reductive state or intermediate oxidation state is oxidized to become high oxidized oligomer, which then takes part in a reaction to synthesize said product, and features gentle reaction condition and simple operation.
Description
The invention belongs to the synthetic technology of phenyl end capped polyphenyl amine oligomer.
That polyaniline has is easily synthetic, can stable existence in air, characteristics such as unique doping phenomenon, excellent electrochemical reversibility, in the past few decades, it has been carried out deep research both at home and abroad.Polyaniline has obtained some application at aspects such as battery, sensor, anti-corrosive paints, because polyaniline is difficult for processing, the defectiveness of molecule own, has therefore limited it and has used widely.
In recent years, started upsurge synthetic and the research polyaniline oligomer both at home and abroad.Human polycondensation methods such as Wudl had synthesized phenyl end capped polyphenyl eight aggressiveness in 1985, it is reported that its electric conductivity and spectrum property and polyaniline are identical.And processing characteristics is better than polyaniline far away.Therefore, some major companies such as IBM have been caused, the very big interest of Unix etc.But because the polycondensation condition of Wudl is very harsh, the today after 10 years, still nobody can repeat out Wudl result then.Recently, the research group of the research group of MacDiarmid and Yen Wei has obtained new breakthrough in the synthetic and application of polyaniline oligomer.It is that benzene one end is the polyaniline tetramer, eight aggressiveness, 16 aggressiveness of amido that people such as MacDiarmid have synthesized an end, and the sensitivity of finding the sensor made with eight aggressiveness is than with several thousand times of polyaniline height.People such as YenWei are raw material with Ursol D and aniline, having synthesized two ends all is the tripolymer of amido, and from tripolymer, synthesized a series of polyaniline oligomer, they have synthesized a series of polymkeric substance with tripolymer, and its corrosion resistance studied, found that its corrosion resistance will be better than polyaniline far away.
Phenyl end capped polyaniline oligomer has very bright application prospect.People's synthetic eight aggressiveness such as Wudl, the electric conductivity of doped hydrochloride are 1.0 Ω
-1Cm
-1, be equal to the electric conductivity of polyaniline.Phenyl end capped polyaniline oligomer is compared with the oligopolymer of other end groups, polyaniline, has the following advantages.The first, to compare with the oligopolymer of Yen Wei with MacDiarmid, phenyl end capped oligopolymer is highly stable, and this helps its processing and use, and self disproportionation reaction easily takes place in air for the above two, becomes complicated product after depositing for some time; Second, compare with polyaniline, there is not defective in the phenyl end capped polyaniline oligomer molecule, its processing characteristics will be better than polyaniline far away, during with other polymer blendings, consistency is better than polyaniline, and the electric conductivity of some phenyl end capped polyaniline oligomers and polyaniline are very approaching again.In a word, phenyl end capped polyaniline oligomer has satisfactory stability, easily process, have consistency preferably with other polymer blending, and some phenyl end capped oligopolymer has very high electric conductivity.
Needing electric conductivity in actual applications is 10
-9-10
-2Ω
-1Cm
-1Material can eliminate static electric charge in travelling belt, carpet, clothes, man-made satellite, Sweet natural gas sleeve pipe.For the electromagnetic shielding material of coating and various case forms, the general requirement electric conductivity surpasses 10
-2Ω
-1Cm
-1, as for the material of making video disc, they are 10 years old
-1Ω
-1Cm
-1Conductive surface, cover with thin dielectric medium, with the oligopolymer of phenyl end capped polyaniline itself, or can satisfy above-mentioned application requiring fully with the material that it and other superpolymer blend obtain.
What especially make us feeling new interest is that in electronic industry, some electronic components need pack with antistatic material in the storage and transport process.At present, because antistatic material does not pass a test, the loss that causes in this respect is very big.Make antistatic material if add metal-powder or carbon black,, need be added to 20-30% and just can reach the conduction stagnation point, film-forming properties and processibility that this will certainly impact polymer according to seepage theory in general-purpose plastics the inside.And the adding conductive polymers only needs to add 2-3% and just can reach the conduction stagnation point.Therefore, if can synthesize the eight phenyl end capped aggressiveness of Wudl in batches, make it and the general-purpose plastics blend, immeasurable market outlook will be arranged in the wrapping material field.
Yet, regrettably, phenyl end capped polyaniline oligomer synthetic but taken a step only difficult in the past few decades, people's such as wudl eight aggressiveness are in 10 years so far thereafter, still nobody can repeat to synthesize, and the method for synthetic eight aggressiveness of people such as wudl, can only synthesize the oligopolymer that phenyl ring is an odd number.And our synthetic route can be synthesized all oligopolymers of phenyl ring from 5 to 99, and the reaction conditions gentleness is simple to operate.
