Preparation of natural polymer-based highly conductive hydrogels with tunable mechanical properties for applications in flexible electronics is still challenging. Herein, we report a facile method to prepare lignin-based Fe3+-rich, high-conductivity via the following two-step process: (1) lignin are prepared by cross-linking sulfonated poly(ethylene glycol) diglycidyl ether (PEGDGE) and (2) Fe3+ ions impregnated into hydrogel simply soaking FeCl3. Benefiting from ion complexation catechol...
Chitosan is a natural polymer derived from the deacetylation of chitin. It mainly crustaceans and fungal sources. has many intrinsic properties, such as biocompatibility, biodegradability, cationic nature, nontoxicity. These features chitosan have made it an attractive material for various applications. Furthermore, these unique properties found significant biomedical applications, in drug delivery, tissue engineering, antimicrobial agent, wound healing. However, its drawbacks, raw source...
Hydrogel-based sensors have attracted increasing attention as fascinating materials for various applications in biomedicine and bioelectronics. However, the application of strain underwater remains a great challenge due to swelling hydrogels an aqueous environment. Herein, we report coacervate conductive polyacrylamide/tannic acid (PAM/TA) composite hydrogel with strong antiswellable properties. The PAM/TA exhibits good electrical performance, where conductivity is found be 2.7 × 10–4 S/cm,...
In this paper, porous scaffolds based on composite hydrogels were fabricated using polydopamine (PDA), chondroitin sulfate (CS), and polyvinyl alcohol (PVA) via the freezing/thawing method. Different characteristics of prepared hydrogels, including pore sizes, compression strength, lap shear mass loss, cytocompatibility investigated. Scanning electron microscope images (SEM) displayed hydrogel ranging from 20 to 100 μm. The exhibited excellent porosity 95.1%, strength 5.2 MPa, 21 kPa porcine...
Hydrogels have drawn intensive attention as fascinating materials for biomedicine. However, fabricating hydrogels with injectable and self-healing properties remains a challenge. Herein, we reported biocompatible poly(N-vinylpyrrolidone)/carboxymethyl cellulose (PVP/CMC) hydrogel excellent properties. The PVP/CMC exhibits good biocompatible, injectable, sol–gel transition of demonstrates an outstanding behavior, the bisected can self-heal within 30 s. swelling ratio, ratio increases...
Sunscreens can help protect the skin from solar ultraviolet (UV) radiation, which is harmful to human health. However, traditional sunscreens penetrate skin, raising concerns about their safety. Therefore, fabrication of a sunscreen with biocompatible, UV-shielding, and antioxidant properties pertinent. Herein, simple method involving self-polymerization dopamine polydopamine (PDA) was proposed for surface modification poly(vinyl alcohol) (PVA) cellulose nanocrystals (CNCs) fabricate...
Lignin-derived chemicals and fuel products have received much attention in the context of bio-refinery. In this study we prepared characterized various lignin samples from black liquor (BL), a major byproduct pulp paper manufacturing processes, studied pyrolysis behaviors these isolated at 600 °C under N2 atmosphere. Three were Kraft pulping BL Loblolly pine linerboard grade process (KL, obtained by direct evaporation; L10, precipitation pH 10; L3, 3), while another three bleach (KB, B10,...
