Jan 1, 2019 · Here we have used chemical oxidative polymerization to synthesize PPY from its monomer pyrrole. We have studied morphological and optical properties of PPY samples by varying the monomer to oxidant molar ratio as 1:1.25 and 1:2 and denoted the samples by 1125ppy and 1200ppy respectively.

Sep 1, 2022 · A cost-effective, scalable, eco-friendly, flexible smart apparel was fabricated by casting method employing polypyrrole(PPy) with biodegradable polyvinyl alcohol on cotton fabric. Different concentration of PPy is embedded in PVA.

May 1, 2021 · In our study, the UV cured acrylate polymer serves as a binder system to provide mechanical integrity to polypyrrole/Ag composite formed via photopolymerization. As reported in our previous work, the conductive polypyrrole/acrylate coatings can be obtained via simultaneous photopolymerization of pyrrole and acrylate monomers.

Nov 12, 2020 · A method of controlling the size and morphology of polypyrrole nanoparticles (PPy-NPs) is successfully developed by using the combination of various non-ionic and anionic surfactants and polymerization temperatures during the synthesis.

Effects of ultraviolet light (325 nm) irradiation on polypyrrole (PPy) properties were studied by time-resolved, standard photoluminescence (PL), optical absorption, and X-ray photoelectron (XPS) spectroscopies. PPy samples were prepared in thin films on gold, quartz, and H-terminated

Among these materials, nanostructured polypyrrole (PPy) has recently been used as photocatalyst for degradation of environmental pollutants under UV as well as visible light.

Polypyrrole (PPy) is an interesting conducting polymer due to its good environmental stability, high conductivity, and biocompatibility. The association between PPy and metallic nanoparticles has...

Polypyrrole (PPy) was synthesized by chemical oxidative polymerization technique using monomer pyrrole and ammo-nium persulphate as an oxidant in a ratio of 1:1. Thin films of polypyrrole were...

In this study, uniform polypyrrole (PPy) nanoparticles were prepared using H 2 O 2 as an oxidant under UV irradiation in the presence of polyvinylpyrrolidone (PVP). The morphology characterization indicated that the spherical PPy nanoparticles were capped by a PVP shell.

Jun 20, 2023 · Molecular orbital interaction between PPy and MB has been explained by UV photoelectron spectroscopy. The present research investigates the photocatalytic activity of pyrrole and polypyrrole (PPy) under visible light for the treatment of contaminated water with the organic dye methylene blue (MB).
