Benefits of technology

This patented technology produces an electrically-conducive film made from polyphenylamines that contains no more atoms compared to existing methods like pyrolithography. It also shows better performance when mixed with different materials such as plasticizers, solvents, resins, rubbers, etc., which makes it useful in electronic devices. Additionally, this new type of chemical called Poly(pimethylenebenzothiophene) (PMBT)) allows for easy production without harmful gases during manufacturing processes. Overall, these technical results make PPMN become increasingly popular over time due its superior properties.

Problems solved by technology

This patent describes various ways to improve the performance characteristics of certain types of conjugated double bonded compounds called phiophiles. These techniques include reducing polar groups near carbon atoms within the backbone of the chromanopyrrolic unit, introducing specific structures like sulfur bridges, attaching alkoxys onto other sites along the periphery of the pyranone core, incorporating hydroxycarboxamides containing nitrile moieties instead of amino acids, and connecting different terminal aliphatic residues together through unsaturation bonds. Additionally, exploring new synthetic routes involving impregnable phases and nonionic charge transfer agents may lead to increased conductivity while minimizing unwanted side effects associated with unstable compositions.

Embodiment 1

[0144] Embodiment 1: the preparation of high conductivity polyaniline (HCPANI)

[0145] In this example the emeraldine base form (EB) of high conductivity polyaniline (HCPANI) was prepared. 100 ml of distilled and purified aniline was slowly added dropwise to 6 liters of 1 mol / liter hydrochloric acid, and then the obtained solution was mixed with 4 liters of isopropanol. The temperature of the mixed solution was kept at -15°C. Ammonium persulfate ((NH 4 ) 2 S 2 o 8 ) 56 g was dissolved in 2 liters of 1 mol / liter of hydrochloric acid to form a solution, and then this solution was slowly added dropwise to the above-mentioned mixed solution under stirring to initiate polymerization, and the time for dropping was 40 minutes. After 3 hours, the polymerization was complete and a precipitate formed. The obtained precipitate was filtered with filter paper, and then washed with 1 liter of 1 mol / liter ammonium hydroxide (NH 4 OH) solution for washing. The precipitate was move

Embodiment 2

[0149] Except that the polymerization reaction temperature was about -25°C, other steps and conditions were the same as in Example 1. The polymerization reaction is carried out for 4-6 hours. It was determined by infrared spectroscopy and NMR analysis (results not shown) that the synthesized substance was emeraldine base polyaniline.

Embodiment 3

[0151] Except that the time for adding the free radical initiator ammonium persulfate was 3 hours, other steps and conditions were the same as in Example 1. The polymerization reaction is carried out for 3 to 8 hours. It was determined by infrared spectroscopy and NMR analysis (results not shown) that the synthesized substance was emeraldine base polyaniline.

Abstract

The present invention relates to a new process of synthesizing conductive polymers from monomers substituted with amine group. The process provides simple synthesizing steps for the conductive polymers without using other additives such as stabilizers or emulsifiers. The conductive polymers synthesized according to the present invention have highly enhanced solubility in common organic solvents and electrical conductivity compared to conventional conductive polymers. Therefore, the conductive polymers synthesized according to the present process can be utilized in applications that require high electrical conductivity, for example an electromagnetic interference shield or a transparent electrode of thin film, as well as in specific applications such as various conductive films, fibers, polymer blends, battery electrodes or conductive etch mask layers.
