Conductive hydrogels have attracted a myriad of interest due to their potential applications for human motion monitoring, personal healthcare diagnosis and so forth. However, fabrication of hydrogel-based strain sensors integrating with ultrastretchability, adhesiveness, strain sensitivity, biocompatibility, and self-cleaning function is still a challenge. Herein, a new type of semiinterpenetrating multifunctional hydrogels, which integrated all above practical features magically were prepared via a facile one-pot in-situ radical copolymerization method. Thereinto, [2-(methacryloyloxy) ethyl] dimethyl-(3-sulfopropyl) ammonium hydroxide (SBMA) and acrylamide (AAm) copolymers cross-linked by N,N 0-Methylenebisacrylamide (MBAA) served as the soft and functional matrix, whereas alginate was employed as the enhanced component. The transparent zwitterionic hydrogels had a max elongation and ionic conductivity of 1353% and 0.15 S/m, respectively. They could adhere onto various surfaces, including steel, glass, skin, and rubber. The repeatable adhesiveness, linear strain sensitivity within 0%-250% tensile strain and 0%-30% compressive strain provided remarkable working range and using stability. What's more notable was that the biocompatibility and self-cleaning function tested by MTT, live/ dead assay, allergy patch tests, and plate colony-counting method imparted great possibility of practical application for strain sensors to hydrogels from a biological point of view.

“…Among the various polymers used in optical energy applications, is the polyaniline (PANI) which is widely studied as a nonlinear optical (NLO) material because of its UV radiation resistance, ultrafast response, steady electrical conductivity, flexibility and easy relative processing [ 5 ]. However, PANI has limited mechanical properties, fusibility, and solubility [ 6 ]. Thus, it has to be modified with other materials to improve these limitations and to enhance its uses, especially in energy applications.…”

In order to potentiate implementations in optical energy applications, flexible polymer composite films comprising methyl cellulose (MC), polyaniline (PANI) and silver nanoparticles (AgNPs) were successfully fabricated through a cast preparation method. The composite structure of the fabricated film was confirmed by X-ray diffraction and infrared spectroscopy, indicating a successful incorporation of AgNPs into the MC/PANI blend. The scanning electron microscope (SEM) images have indicated a homogenous loading and dispersion of AgNPs into the MC/PANI blend. The optical parameters such as band gap (Eg), absorption edge (Ed), number of carbon cluster (N) and Urbach energy (Eu) of pure MC polymer, MC/PANI blend and MC/PANI/Ag films were determined using the UV optical absorbance. The effects of AgNPs and PANI on MC polymer linear optical (LO) and nonlinear optical (NLO) parameters including reflection extinction coefficient, refractive index, dielectric constant, nonlinear refractive index, and nonlinear susceptibility are studied. The results showed a decrease in the band gap of MC/PANI/AgNPs compared to the pure MC film. Meanwhile, the estimated carbon cluster number enhanced with the incorporation of the AgNPs. The inclusion of AgNPs and PANI has enhanced the optical properties of the MC polymer, providing a new composite suitable for energy conversion systems, solar cells, biosensors, and nonlinear optical applications.

“…Currently, several studies have been conducted to increase mechanical strength, reduce electrical resistance, and confer self‐healing ability to hydrogels. Jin et al 20 prepared PAni‐PAAm‐GOCS conductive hydrogels by two‐step in situ radical polymerization of acrylamide (AAm) and aniline (Ani) in graphene oxide (GO) and chitosan (CS) matrices, with tensile strength up to 0.80 MPa and elongation at break and conductivity of 360% and 2.88 S/m, respectively. Wang et al 21 designed a novel dynamic oxidation and coordination system consisting of modified water‐soluble lignin and Fe 3+ .…”

Lightweight, thin, and stretchable flexible microelectronic devices have become a new challenge for researchers. To provide power for these conformable devices, it is necessary to design the energy storage device into a flexible and stretchable structure. In this paper, a two‐step method was used to prepare a dual‐physical cross‐linked polyacrylic acid/chitosan/Ti3C2Tx(PCT) conductive hydrogel flexible electrode. The three‐dimensional (3D) porous structure not only offers a good electrical connection, but also saves the use of binder and additional current collector, which helps to enhance the electrochemical properties of electrode. The unique two‐dimensional layered structure of Ti3C2Tx enables the hydrogel electrode to withstand considerable pressure deformation without breaking, and has excellent tensile properties. The flexible electrode exhibited an excellent tensile strength of 0.083 MPa if only introduced 0.31 wt% of Ti3C2Tx with the tensile strain of 158.63% and owned remarkable self‐healing properties after injury. Thereby, the hydrogel electrode renders a maximum capacitance of 291.8 mF g−1 at 0.5 mA/g and a good cycling stability with 64.24% capacitance retention after 2000 charge–discharge cycles. This provides a research and development strategy for binder‐free, non‐toxic, and mini‐size flexible energy storage devices.
