Is polyaniline water soluble?
Pure polyaniline (PAni) is insoluble in water. Water-soluble complexes of PAni with different of cellulose derivatives were successfully synthesized by using chemical oxidation polymerization of aniline in aqueous solution of cellulose derivatives.
What is the structure of polyaniline?
Polyaniline (PANI) is a conducting polymer and organic semiconductor of the semi-flexible rod polymer family. The compound has been of interest since the 1980s because of its electrical conductivity and mechanical properties. Polyaniline is one of the most studied conducting polymers.
How do you make Polythiophene?
Polythiophene can be synthesized by major two types one is electrochemically by applying a potential across a solution of the monomer to be polymerized. Another one is chemically using oxidants or cross-coupling catalysts. The quality of electrochemically prepared PT thin films is affected by a number of factors.
What is polyaniline soluble?
Polyaniline is soluble in NMP as well as in DMF but not 100% soluble. So you can try Camphoresulfonic acid (CSA) treated PANI in DMF or NMP. Treating with CSA can increase the solubility of PANI. Cite.
Is polyaniline soluble in chloroform?
A mixture of toluene and 2-propanol, was used by Shreepathi, S. and Holze, R. for polymerization of aniline, soluble in chloroform, 2:1 mixture of toluene and 2-propanol, NMP and dichloromethane [7,10]. Later on, pure toluene was used as a dispersion medium but the solubility was reduced [11].
How do you dissolve polyaniline?
A new inverse emulsion protocol has been developed for the synthesis of polyaniline (PANI), which can be dissolved completely in common organic solvents such as chloroform. Benzoyl peroxide is used as the oxidizing agent and toluene + 2-propanol-water is used as the solvent.
What is the Colour of polyaniline?
For doped polyaniline, or as you said in acidic condition, polyaniline exists in emerladine salt form, which is green in color.
Is Polythiophene soluble?
Polythiophene and its oxidized derivatives have poor processing properties. They are insoluble in ordinary solvents and do not melt readily. For example, doped unsubstituted PTs are only soluble only exotic solvents such as arsenic trifluoride and arsenic pentafluoride.
Is Polythiophene a semiconductor?
Polythiophene (PTh) and its derivatives are polymer-based materials with a π-conjugation framework. PTh is a useful photoelectric material and can be used in organic semiconductor devices, such as PLED, OLED, and solar cells.
