Synthesis and studies of semiconducting piperazine–aniline copolymer

A study on the electrochemical oxidation of piperazine and its electrochemical copolymerization with aniline in acidic medium is presented. It was found that the homopolymerization of piperazine cannot be achieved under electrochemical conditions. A combination of electrochemistry, in situ Fourier transform infrared (FTIR), and ex situ X-ray photoelectron spectroscopy (XPS) spectroscopies was used to characterize both the chemical structure and the redox behavior of an electrochemically synthesized piperazine–aniline copolymer. The electrochemical sensing properties of the deposited material were also tested against ascorbic acid and dopamine as redox probes.

“…Literature survey has revealed that copolymerization has emerged as a very strong, attractive, and challenging discipline in chemical research,22–31 however, traditional polymerization32–35 of aniline involves some oxidizing agents such as Ammonium Persulfate, K 2 Cr 2 O 7 , FeCl 3 , KMnO 4 , BrO 3 , KClO 3 , Tetrabutylammonium persulfate (TABP), H 2 O 2 , etc., and results in the formation of insoluble and infusible polymer along with used oxidant by‐products which are difficult to separate. These methodologies suffer from drawbacks like removal of by‐products, wide range of polymer molecular weight, long reaction time, high temperature requirement, negative impact of oxidants on the environment and toxic effect on human beings.…”

“…Density is mass of the liquid per unit volume or it is also the compactness of the molecules of liquid measured at 15°C. A Specific gravity bottle was used to measure density [13]. It was washed thoroughly by distilled water and acetone and then dried in the furnace for about 5 -10 minutes.…”

The field of application of Magnetorheological fluids (MRF) is widening. The carrier fluids being used now are synthetic, expensive and non-biodegradable. Hence, there is a need for looking for better and inexpensive alternatives. This study was intended to uncloak alternatives to the synthetic carrier fluids by taking four natural oils and conducting various tests. The four natural oils, viz, Simarouba Oil, Mahua Oil, Groundnut oil, Flaxseed oil and synthetic Silicone oil were taken and tests concerning Magnetorheological fluids like density, kinematic viscosity, flash and fire point, pour point, etc., were conducted according to standards in a licensed laboratory. Based on the various tests conducted, the four natural oils have shown remarkable potential compared with commonly used silicone oil to be used as carrier fluids.
