“…Importantly, the adhesive electrodes attached to the palm muscle of the female volunteer's arm achieved accurate collection of epidermal electrical signal changes caused by the volunteers' arm-clamping, relaxation, and straightening muscle switching (Figure 3b). Similarly, volunteers' complete ECG and heart rate could also be accurately monitored by the adhesive electrodes ( Figure 3c) [5]. Adhesive hydrogel can increase the service life of the electrode and prevent it from falling off the skin, thereby affecting the stability of the signal.…”

Inspired by mussel adhesion chemistry and ion electronics, a novel Ca2+-tannic acid@ sulfonated lignin-polyacrylamide (TA@SL-PAM) hydrogel was prepared via Ca2+-TA@SL composites and the PAM system, where a Ca2+-TA@SL composite was fabricated via TA doping with SL and the subsequent adsorption of Ca2+. The properties of the hydrogel were thoroughly investigated and the hydrogel was presented as multifunctional. The introduction of Ca2+-TA@SL composites endowed the hydrogel with excellent conductivity, adhesion and ultraviolet (UV) resistance, and improved antioxidant and antibacterial properties. More importantly, the Ca2+-TA@SL-PAM hydrogel electrode could accurately detect physiological signals of human (e.g., electrocardiogram (ECG), electromyography (EMG).

“…[31,32] The modified lignin can be used as a surfactant, including an adhesive, an oil drilling additive, a coal water slurry dispersant, a cement water reducing agent, and so on. [33,34] As kraft lignin can only be dissolved in an alkaline solution, its industrial application is heavily hindered. Therefore, our study uses kraft lignin as a raw material and glycidyl trimethyl ammonium chloride (EPTAC) as quaternization reagent to prepare new products by graft copolymerization and increase the water solubility of kraft lignin, and this method ( Figure 1) expands the lignin derivative lignin-EPTAC as an excellent corrosion inhibitor.…”

Organic corrosion inhibitors from natural plant resources have received extensive attention in recent years. Herein, an eco-friendly corrosion inhibitor lignin-(2,3-epoxypropyl)trimethyl ammonium chloride (EPTAC) was successfully prepared by grafting EPTAC to kraft lignin. The inhibiting efficiency and its inhibition mechanism were investigated using electrochemical methods, adsorption thermodynamics analysis, and molecular dynamic simulation. The results showed that the lignin-EPTAC molecules formed a protective film on iron surface, resulting in an excellent inhibition efficiency of 97.80% at 100 mg/L concentration. The average surface roughness of steel samples was reduced to 26.6 nm from the original 99.3 nm. The adsorption of lignin-EPTAC molecules on the steel surface follows Langmuir adsorption isotherm model and was a physical-chemical process as well as an exothermic process of entropy reduction. This adsorption of lignin-EPTAC was a conjugated system dominated by benzene ring of lignin-EPTAC to form a chemical bond on the steel surface by conjugation, besides a positive interaction between the metal surface and the positively charged N ions in the head group of lignin-EPTAC.

“…Here, we report a simple strategy using a lignin nanoparticle (LNP)-coated Celgard (LC) membrane as a novel separator for Li-S batteries. The low cost and abundant quinone of lignin engender a versatility for its application in diverse technologies such as sensors [30,31], solar cells [32], supercapacitors [33,34], and lithium-ion/sodium-ion batteries [35,36]. Thanks to their good dispersity [28,29], LNPs are easily deposited on a conventional Celgard separator by simple filtration to obtain a composite separator.…”

Tremendous efforts have been made toward the development of lithium–sulfur (Li–S) batteries as one of the most reasonable solutions to the rapidly increasing demand for portable electronic devices and electric vehicles, owing to their high cost-efficiency and theoretical energy density. However, the shuttle effect caused by soluble polysulfides is generally considered to be an insurmountable challenge, which can significantly reduce the battery lifecycle and sulfur utilization. Here, we report a lignin nanoparticle-coated Celgard (LC) separator to alleviate this problem. The LC separator enables abundant electron-donating groups and is expected to induce chemical binding of polysulfides to hinder the shuttle effect. When a sulfur-containing commercially available acetylene black (approximately 73.8 wt% sulfur content) was used as the cathode without modification, the Li–S battery with the LC separator presented much enhanced cycling stability over that with the Celgard separator for over 500 cycles at a current density of 1 C. The strategy demonstrated in this study is expected to provide more possibilities for the utilization of low-cost biomass-derived nanomaterials as separators for high-performance Li–S batteries.
