“…Change from a glassy to a rubbery or highelastic state happened after T g , caused the chain segment to gradually recover its motion ability, and E' rapidly decreased. It is worthy of mention that the tan δ peak height was higher in the biocomposites, thus indicating the higher damping properties due to the physical nature of the lignin and implying that lignin had good compatibility with the polymer matrix [16,55]. Furthermore, the presence of a well-defined peak in the loss factor has been considered another piece of evidence indicating a homogeneous microstructure of the blend and the miscibility of the components [54].…”

“…As a by-product of the paper industry, lignin is considered a waste product; therefore, its utilization for unique applications has raised significant interest both scientifically and industrially. This high carbon content material is being extensively used as a reinforcement material for polymer biocomposite production due to its abundant availability, sustainability, biodegradability, rigidity, and adequate thermal stability, as well as antibacterial and anti-oxidating activity [16][17][18]. Furthermore, it has been reported that using lignin as a filler reduces material costs [19,20].…”

“…[144,145] As lowcost biomaterials, lignin exhibits superior biocompatibility, thermal stability, nontoxicity, and environmental affinity. [119,146] Noteworthily, lignin possesses strong adhesion through covalent and noncovalent bond interactions, such as hydrogen bonding, metal coordination, as well as hydrophobic and ionic interactions, which can be attributed to its multiple functional groups including phenolic hydroxyl and pyrogallol groups. [147][148][149][150] Most adhesive hydrogels possess uniform adhesive performance, which means that both sides of the adhesive layer have strong adhesion.…”

Stable ambulatory electrophysiological sensing is widely used for smart e-healthcare monitoring, clinical diagnosis of cardiovascular diseases, treatment of neurological diseases, and intelligent human-machine interaction. As the favorable signal interaction platform of electrophysiological sensing, the conformal property of on-skin electrodes is an extremely crucial factor that can affect the stability of long-term ambulatory electrophysiological sensing. From the perspective of materials, to realize conformal contact between electrodes and skin for stable sensing, highly conformal polymers are in great demand and attracting ever-growing attention. This review focuses on the recent progress of highly conformal polymers for ambulatory electrophysiological sensing, including their synthetic methods, conformal property, and potential applications. Specifically, three main types of highly conformal polymers for stable long-term electrophysiological signals monitoring are proposed, including nature silk fibroin based conformal polymers, marine mussels bioinspired conformal polymers, and other conformal polymers such as zwitterionic polymers and polyacrylamides. Furthermore, the future challenges and opportunities in preparing highly conformal polymers for on-skin electrodes are also highlighted.

“…Lignin is a renewable and naturally available material, considered the second most abundant biomacromolecule (after cellulose). , Lignin is also relatively inexpensive, biodegradable, and has substantial antioxidant and antibacterial properties . Therefore, the preparation of polymer hybrid materials, with lignin as a filler, has been the scope of several studies. ,− It was shown that polymer/filler compatibility plays a major role in enhancing the crystallization kinetics of the hybrid, , where incompatible, phase-separated mixtures always lead to undesired results and deteriorated properties . Although lignin shows unfavorable interactions with most synthetic polymers and natural rubbers, it has good affinity to PEO .…”

Supernucleation Dominates Lignin/Poly(ethylene oxide) Crystallization Kinetics

The effect of lignin nanoparticles (LNPs) on the crystallization kinetics of poly(ethylene oxide) (PEO) is examined. Lignin from spruce and ionic isolation was used to prepare LNPs with a number-averaged diameter of 85 nm (with a relatively large polydispersity) by an ultrasonication method. PEO-based nanocomposites with four different LNP contents (5, 10, 15, and 20 wt %) were prepared and subject to isothermal and nonisothermal crystallization protocols in a series of experiments. Scanning electron microscopy (SEM) images showed welldispersed LNPs in the crystallized PEO matrix. The incorporation of LNPs exponentially increases nucleation density at moderate loadings, with this trend apparently saturating at higher loadings. However, the spherulitic growth rate decreases monotonically with LNP loading. This is attributed to the substantial PEO/LNP affinity, which impacts chain diffusion and induces supernucleation effect (with efficiencies in the order of 200%), but leads to slower growth rates. The overall crystallization kinetics, measured by the DSC, shows faster nanocomposite crystallization rates relative to the neat PEO at all LNP contents examined. This indicates that the supernucleation effect of LNPs dominates over the decrease in the growth rates, although its influence slightly decreases as the LNP content increases. The strong hydrogen-bonded interactions between the LNPs and the PEO are thus reminiscent of confinement effects found in polymer-grafted NP nanocomposites (e.g., PEO-g-SiO 2 / PEO) in the brush-controlled regime.
