This study is purposed with the preparation of polyacrylamide/Polypyrrole hydrogel composite, in which the hydrogel of crosslinked polyacrylamide is a matrix and Polypyrrole is an electro-conducting component. The effects of synthesis conditions on the structure of the composite systems, their ability to swell in water, and mechanical characteristics are studied. The proposed synthesis procedur...

polypyrrole is one of the most useful conductive polymers, but green synthesis of this polymer has been restricted until now. the objective of the present paper is green synthesis of nano polypyrrole (ppy) by oxidative polymerization using urea-hydrogen peroxide. it was found that conductivity and morphology of polypyrrole are highly dependent on the reaction conditions such as the molar ratio ...

H2S gas sensors were fabricated using Ag nanowire/hollow polypyrrole nanotube nanocomposite (Ag NW/hollow PPy NT) film for sensing ppb-level at room temperature. The morphology, phase composition and crystalline structure of NT nanocomposites analyzed via scanning electron microscopy (SEM), transmission (TEM), X-ray diffractometry (XRD) Fourier-transform infrared spectroscopy (FTIR). TEM SEM im...

Initially, pristine polymers were used to develop corrosion-resistant coatings. Later, the trend shifted use of polymeric nanocomposites in anti-corrosion materials. In this regard, graphene has been identified as an important nanomaterial. Consequently, polymer/graphene have applied for erosion protection applications. Among polymers, conducting (polyaniline, polypyrrole, polythiophene, etc.) ...

Lithium-ion batteries have evolved and transcended in recent years to power every device across the spectrum, from watches electrical vehicles beyond. However, lithium-ion battery requires use of heavy expensive transition metal oxides that limited life cycles. Conductive polymer nanocomposites been shown possess good electrochemical thermomechanical properties are considered be effective alter...

This paper describes the establishment of free-standing rolled graphene oxide (roll-GO) and polypyrrole (Ppy) using a modified Hummer method oxidative polymerization. Then, photodetector was created by removing thin film from filter attaching it to tape. The chemical structure roll-GO confirmed XRD FTIR analysis, while SEM TEM showed that in nature. material had small bandgap 2.4 eV high curren...
