A simple route to synthesize conductive stimuli-responsive polypyrrole nanocomposite hydrogel particles with strong magnetic properties and their performance for removal of hexavalent chromium ions from aqueous solution

Impact of mesoporous SiO2 support for Ni/polypyrrole nanocomposite particles on their capacitive performance

“…The characteristic CC and C–N stretching vibrations appear at 1575 and 1416 cm −1 , respectively. 53 The signals at 1044 and 924 cm −1 are assigned to the C–H in-plane bending and the ring deformation. 54 On the other hand, the spectrum of H 2 N-SiO 2 /Ni/PPy nanocomposite particles (Fig.…”

Layer‐by‐layer preparation of electromagnetic NH2‐SiO2/polypyrrole/Ni nanocomposites, characterization and their electrochemical properties

“…PPy is also known for its ability to interact with drugs and biomolecules through large amounts of secondary amine groups. But in many industrial applications, PPy alone is not suitable because of poor processability, low solubility in common solvents, poor mechanical strength and poor dispersion stability 14,20 . To overcome these limitations, researchers are showing interest in designing new electroconducting stable composites comprising an organic or inorganic core and a PPy shell 10,21–29 .…”

Multiphotoinduced Bending of Azobenzene-Modified Graphene Oxide/Poly(vinyl alcohol) Composite Films for Smart Devices

“…Smart materials that can respond to external stimuli by changing their physico-chemical properties have potential applications in electronic skin, artificial muscles, , drug delivery systems, , and light-driven motors . Various stimuli such as heat, light, electrical field, magnetic field, pH, and ionic intensity are widely utilized. − Among them, light has the advantages of being easily accessible, remotely controllable, and environmentally friendly, and thus, photoresponsive materials are attracting increasing attention of researchers. Azobenzene is a kind of typical photochromic molecule.…”
