A method for the removal of anionic (sulfonated) dyes from aqueous dye solutions using chemical interaction molecules with polyaniline is reported. Polyaniline (PANI) emeraldine salt was synthesized by oxidation. Sulfonated undergo interactions charged backbone PANI, leading to significant adsorption dyes. This phenomenon selective PANI reported first time and promises a green sulfonated organics wastewater. The experimental observations UV-vis spectroscopy, X-ray diffraction, conductivity...
In this study, we report an approach for the adsorption and desorption of anionic (sulfonated) dyes from aqueous solution by doped polyaniline. have synthesized PANI with two dopants, namely, p-toluenesulfonic acid (PTSA) camphorsulfonic (CSA), used these to adsorb various dyes. It was found that selectively adsorbs does not cationic The causes variation in electrical conductivity PANI, indicating its potential as a conductometric sensor at very low concentration. adsorbed were desorbed...
Conductive cotton + PANi fabrics are prepared by in-situ chemical oxidative polymer ization of aniline using ammonium persulphate as the oxidant a process diffusion polymerization in mixed bath. These characterized elemental analysis, XRF, ATR-FTIR, WAXD, SEM, DSC, and two-probe conductivity. Sorption properties studied measuring weight uptake before after reaction. The composite for their performance repeated washing, tested flame retardancy, EMI shielding, gas sensing properties.
Abstract Natural fiber composites are the subject of significant research because environmental concerns worldwide. In this perspective, present study explores suitability silica-rich rice paddy straw (PS), an agricultural waste to create a biodegradable material for use in industries such as automotive, packaging, construction and furniture (e.g. particle boards). This approach aims reduce damage caused by burning PS fibers deforestation. Several researchers have used filler up 40%. The...
The conducting polymers such as polyaniline, polypyrrole and polythiophene were functionalized with copper phthalocyanine using chemical oxidation method. obtained viz. PANI-CuPc, PPy-CuPc PT-CuPc studied sensors by their response characteristics after exposure to various vapors methanol, ammonia nitrogen dioxide. results showed that these have moderate sensitivity towards the methanol well whereas they show tremendous dioxide vapors. factor of high 50,000 was for in In comparison this,...
Polypropylene (PP)-Flyash (FA) composites containing natural banana fiber (NF) treated by Maleic anhydride and NaOH are reported here. Mechanical properties such asflexural modulus impact strength were improved considerably which maximum for 20% fly ash filled PP-NF composites. There is extensive nucleation of theα crystalline phase PP in presence the additives. This changed to mixed α with slight β content FA NF as confirmed XRD DSC. The results on mechanical have been explained basis...
A conducting polymer-based chemical sensor was fabricated by depositing a film containing polyaniline blended with polyethylene oxide and doped copper chloride onto interdigitated electrodes in surface cell configuration. It found to be very sensitive alcoholic vapours, especially methanol. Its characteristics such as response time (tr), recovery (td), sensitivity factor (σmax/σ0), etc. have been studied respect composition, vapour dosage, that the maximum tr minimum at certain concentration...
