Enhancement of electric conductivity by incorporation of Ag into core/shell structure of Fe3O4/Ag/PPy NPs

Design and performance of polypyrrole/halloysite nanotubes/Fe3O4/Ag/Co nanocomposite for photocatalytic degradation of methylene blue under visible light irradiation

“…At first, 0.3 g of halloysite/Fe 3 O 4 in 20 mL of distilled water was stirred for 2 h at room temperature and then 0.1 g of PVP in a 0.2 M solution of AgNO 3 was dissolved in a 10 mL of distilled water. In the next step, 5 mL solution containing 0.084 g of NaBH 4 was added dropwise [20,21].…”

Electroconductive and catalytic performance of polypyrrole/montmorillonite/silver composites synthesized through in situ oxidative polymerization

“…In addition, using silver nitrate as a direct oxidant of Py monomer for the production of conducting PPy/Ag composites has been reported . PPy/Ag composites loading on oxide metal, fabric cotton, cellulose, or polymer membrane has been discussed. In this single‐step process, reduction of Ag + to the metal on the PPy surface was found to be caused by the redox reaction between the positively charged and growing Py chains.…”

“…Conducting polymers has been extensively studied for many applications such as gas sensors, batteries, actuators, corrosion inhibition, and water purification . Among various conducting polymers, PPy has become frequently studied because of its good electrical conductivity, environmental stability, and easy synthetic process . Recently, PPy/clay composites have gained significant interest for important technological applications, such as gas sensors, semiconducting nanomaterial, cathode material for oxygen reduction, metal corrosion protection, and removal of metal .…”

Dielectric, magnetic and microwave absorbing properties of polypyrrol-Co0·7Cu0·1Zn0·2Fe2O4 nanocomposites

“…[6][7][8][9][10] As a conducting polymer, polypyrrole has become one of the most attractive research topics due to its adjustable conductivity, easy synthesis, and good environmental stability. [11][12][13][14] Ferrite is one of the most promising materials in magnetic nanocomposites for the absorption of microwave radiation. 15 A number of researches have been reported on studying the synthesis, structure and electromagnetic properties of spinel ferrites in recent years.…”
