“…Besides, peak of 1,070 cm −1 can be assigned to the N Q N stretching (Q is the quinonoid ring). [17,18] The main difference between the spectra of these samples based on different substrates lies in the relatively intensity of the peaks corresponding to N Q N (1,070 cm −1 , marked as I A ) and C C (1,571 cm −1 , marked as I A ). For PANI polymerized on nylon membrane of 0.1 μm, the ratio between I A and I B is >1; however, for PANI deposited on nylon-0.22 μm the intensity ratio of I A /I B decreased obviously and close to 1.…”

Polyaniline (PANI) films and its electrochromic devices based on various porous substrates were obtained by electrochemical deposition. The pore size distribution of the porous substrate has shown important influence on the infrared emissivity variation (Δε) of the device. Morphology and structure of PANI were characterized by scan electronic microscopy (SEM) images and Fourier transform infrared spectra (FTIR). SEM images present the morphology difference of PANI on different substrates, which suggest that large pores will prevent PANI particles from forming orderly and compactly films. FTIR spectrum indicates that pore size of substrates affects the orientation of PANI chains. Furthermore, electrochemical properties and stability of PANI films were analyzed by cyclic voltammetry (CV) curves. And the CV curve revealed that the generation of irreversible degradation products is the reason for poor stability of PANI films. Finally, greatly improved Δε of 0.559 in 3-5 μm waveband and 0.39 in 8-14 μm waveband is achieved by choosing a small pore substrate.

“…It is well-known that the metal-based heating source also suffers from many drawbacks, such as the heavy weight, inferior flexibility, atmospheric oxidative corrosion, and high-processing price . Especially, the high voltage is applied on the ETC fabric with high resistance for driving the color change, restricting its applications in wearable facilities where the high voltage is not allowed for the human safety. , For improving the heating resource conductivity, the conductive materials, such as polypyrrole (PPy), polyaniline (PANI), and graphene, are considered as excellent candidates to replace the metal wires due to their excellent conductivity, superior flexibility and environmental stability. − Because of the virtues of its soft carbon-based nature, high carrier mobility, and ultrathin form factor, graphene possesses superior mechanic stability, outstanding conductivity, and flexibility, which makes it a suitable material for personal thermal management and healthcare devices. Graphene as a very appealing material has been widely applied to the assembly of flexible conductive devices based on the paper and PET film, however, it is still a great challenge in the preparation of the graphene conductive fabric with excellent flexible and high thermally conductivity.…”

A sensitive electro-thermochromic Janus fabric driven by voltage is demonstrated via a facial double side coating. The graphene forms a conductive layer that allows Joule heating to supply the thermal resource for the electro-thermochromic behavior of polyester fabric. The thermochromic dye with reversible color-changing property is coated on the opposite side of the graphene layer. The color of electro-thermochromic Janus fabric changes from blue to white with a gradual heating that exceeded 45 °C at the applied voltage of 10 V. The switching rate of color is rapid with the increase of temperature from the room temperature to above 45 °C in 8 s, resulting from the superior resistive heating of the graphene. The electrical conductivity of the electro-thermochromic Janus fabric is not disturbed once undergoing a bending angle range from 30° to 150° and the temperature remains stable after 1000 bending cycles which clearly indicates the excellent flexibility of the fabric. The steady signal in the heating/cooling curve is observed after 500 cycles, pointing out the outstanding durability of the electro-thermochromic Janus fabric under the supplied voltage. It is realizable that the color of electro-thermochromic Janus fabric is triggered accurately by varying the supplied voltage. The simplicity of this design makes it attractive for the application of flexible electro-thermochromic textile, such as active visual camouflage, personal thermal management, and information displays.

An electrochemical approach towards developing a lead(II) ion selective polymer is presented. A poly(aniline-co-3-aminobenzenesulfonic acid), P(Ani-co-3ABSA), membrane would be reconciled with the peculiarities of lead(II) ions by incorporating them. It seems that consecutive embedding/ejecting of lead(II) into-from the mass of P(Ani-co-3ABSA) coating, correspondingly templates the coating towards lead(II) ion. This method results in a highly selective sensor for the measurement of lead(II) ion. The optimal conditions for sensor operation were ascertained. The surface morphology of the freshly synthesized, templated and templated-preconcentrated P(Ani-co-3ABSA) membranes were explored by SEM. The interference effect on the voltammetric response with coexisting ions was also investigated. The developed sensor was applied for lead(II) determination by pre-concentration/differential pulseanodic stripping voltammetry in concentrations of 1.0 nM to 0.1 mM and by potentiometric method in concentrations of 10.0 nM to 1.0 mM.
