Polypyrrole micro/nanostructures and their soft materials in versatile forms: construction and applications

Abstract

With arousing research interest in the fields of advanced materials, energy conservation and environment protection, polypyrrole (PPy), as a widely studied conducting polymer, has exuded new vitality for a lot...

Phytic acid/tannic acid reinforced hydrogels with ultra-high strength for human motion monitoring and arrays

“…23,24 However, pure PVA hydrogels have weak mechanical strength, limited functionality, and poor conductivity. 25 While the introduction of materials like polypyrrole, 26 polyaniline, 27 ammonium sulfate ions, 28 graphene oxide, 29,30 and clay 31 enhances PVA hydrogel performance, it often sacrifices environmental friendliness. Inspired by plants, phytic acid and tannic acid are biomacromolecules derived from plants, serving as rich, non-toxic, and environmentally friendly biomass materials.…”

Electrorheological and magnetorheological properties of liquid composites based on polypyrrole nanotubes/magnetite nanoparticles

“…This unique feature is attributable to the specific nature of the embedded microparticles, which react to magnetic field variations, thereby transforming the physical properties of the composite. This adaptability and responsiveness to external stimuli are crucial characteristics that open up new possibilities in the development of adaptive and responsive material systems [10,29]. Such duality in response mechanisms significantly emphasizes the potential of PPy-based composites, paving the way for their application in a broad spectrum of advanced smart materials.…”
