“…Remarkably, the transparency drop of our hydrogel against thickness was significantly small in comparison. The PDA–PPy–PAM hydrogel still showed high optical transmittance even at a thickness of 3 mm, which surpassed the performance of previously reported conductive and transparent materials with directly blended CP nanofillers because they only allowed light to pass through when their thickness was on the nanometer or micrometer scale. ,,− …”

Conductive hydrogels are promising materials for soft electronic devices. To satisfy the diverse requirement of bioelectronic devices, especially those for human–machine interfaces, hydrogels are required to be transparent, conductive, highly stretchable, and skin-adhesive. However, fabrication of a conductive-polymer-incorporated hydrogel with high performance is a challenge because of the hydrophobic nature of conductive polymers making processing difficult. Here, we report a transparent, conductive, stretchable, and self-adhesive hydrogel by in situ formation of polydopamine (PDA)-doped polypyrrole (PPy) nanofibrils in the polymer network. The in situ formed nanofibrils with good hydrophilicity were well-integrated with the hydrophilic polymer phase and interwoven into a nanomesh, which created a complete conductive path and allowed visible light to pass through for transparency. Catechol groups from the PDA–PPy nanofibrils imparted the hydrogel with self-adhesiveness. Reinforcement by the nanofibrils made the hydrogel tough and stretchable. The proposed simple and smart strategy of in situ formation of conductive nanofillers opens a new route to incorporate hydrophobic and undissolvable conductive polymers into hydrogels. The fabricated multifunctional hydrogel shows promise in a range of applications, such as transparent electronic skins, wound dressings, and bioelectrodes for see-through body-adhered signal detection.

“…In the second way, as long as the average diameters of the conductive fillers are less than half of the shortest wavelength of visible light, the conductive films obtained could be rendered transparent. For instance, Huijs et al [17] prepared polypyrrole coated latex particles in diameters of ∼0.7 m and fabricated transparent and conductive polymeric films with these particles. However, the transparency of the films deteriorated greatly with increasing of the filler contents, which was resulted from the size of the conductive fillers.…”

“…The PA composites modified by functionalized acids (mainly dodecyl benzene sulfonic acid (DBSA) and camphor sulfonic acid) were soluble in toluene, xylenes, decalin, etc. Huijs et al [16] had prepared transparent polymer films with an electrical conductivity in the antistatic range using polypyrrole-coated latex particles with particle size of about 700 nm.…”

“…Several studies on the preparation of PA with different particles, such as TiO 2 , Fe 2 O 3 , and metals like Pt, Ag, and Au, were also intensively reported [16][17][18][19]. The PA/carbon filler composites, prepared by in situ polymerization [20], exhibited greatly improved conductivity, thermal stability, and mechanical properties in comparison with the pure PA.…”

A series of core-shell particles (SMAP/G) having polystyrene-methylacrylate copolymer (styrenemethyl acrylate) as the core and graphite incorporated polyaniline as the shell were prepared by surfactant free mini-emulsion polymerization. Here poly (SMA) copolymer latex particles were first dispersed in water and then coated with polyaniline (PA) by in situ polymerization of aniline in presence of different percentage (0.25, 0.50 and 1.0%) of graphite. The composite particles were characterized by FTIR, XRD and TGA. TEM and SEM analysis confirms the core-shell morphology of the composite particles. DC electrical conductivity values of all the samples were measured by using a standard four-probe method. The effect of temperature and the amount of graphite incorporated into the PA shell on the dc electrical conductivity of the core-shell composites was investigated. The electro chemical behaviour of the core-shell composites was studied by using a cyclic voltammeter. Electro chemical data shows that the core-shell composites are sufficiently stable under redox potential of 50 mV/s to find applications in various electronic devices.
