Antimicrobial materials are an urgent need for modern wound care in the clinic. Although traditional polyurethane foams have proven to be clinically valuable treatment, their petroleum-originated preparation and bioinert nature restricted efficacy biomedical applications. Here, we propose a simple one-step foaming method prepare lignin-based (LPUFs) which fully biobased polyether polyols partially replace petroleum-based raw materials. The trace amount of phenolic hydroxyl groups (about 4 mmol) liquefied lignin acts as direct reducing agent capping silver ions (less than 0.3 mmol), situ forming nanoparticles (Ag NPs) within LPUF skeleton. This newly proposed polyurethane/Ag composite foam (named Ag NP-LPUF) shows improved mechanical, thermal, antibacterial properties. It is worth mentioning that NP-LPUF exhibits more 99% rate against Escherichia coli 1 h Staphylococcus aureus h. Evaluations mice indicate antimicrobial can effectively promote healing full-thickness skin defects. As proof concept, this biodegradable significant potential clinical translation dressings.

Abstract Foam thermal insulators are indispensable for prevailing energy‐saving engineering, however their widespread use brings intractability such as unsustainability, “white pollution”, and fire hazards. The emergence of bio‐based foams is highly appreciated, but the fabrication approaches economically unattractive and/or product properties inferior, making large‐scale implementation unviable. Herein, a versatile, thermally remoldable phosphate‐containing polyurethane composite foam (LPU‐G) constructed from natural lignin expanded graphite flakes via an atmospheric pressure scalable one‐pot strategy. optimal LPU‐G exhibits exceptional mechanical strength, capable supporting over 6000 times its weight without significant deformation. Moreover, demonstrates desired multifunctionality in handling extreme circumstances, including humidity‐tolerant insulation, superb water vapor barrier, withstanding ≈1200 °C flame ignition. Based on “expansion‐conductivity” micro‐mechanism, first material to be sensitive alarm system with ultra‐long time (>1800 s). Surprisingly, can rapidly upcycled into recyclable bulk composites second life through simple thermo‐molding processes rooted multi‐dynamic behavior phosphate, carbamate, hydrogen bonds. easy‐to‐scale represents new generation that address concerns regarding high cost, risk, inferior properties.

Medical dressings, as a cover for wounds, can replace damaged skin in the wound healing process to play temporary barrier role, avoid or control infection, and provide favorable environment healing. Therefore, there is an urgent need medical antimicrobial dressings treatment of chronic wounds. Although traditional polyurethane foam has been widely used conventional foams are primarily prepared using nonbiocompatible isocyanate-based compounds, which potentially hazardous both operators applications field. Here, we propose nonisocyanate naturally derived from lignin by enzymatic alkylation, cyclic carbonation modification, polymerization with diamine addition blowing agent. Silver nanoparticle solution was added during foaming confer properties. This lignin-based polyurethane/silver composite (named NIPU foam-silver) green synthesis method good mechanical properties, be manufacture foams, thermal Notably, foam-Ag showed more than 95% bactericidal efficacy against Escherichia coli Staphylococcus aureus within 4 h. Evaluation vitro wounds mice that this rapidly promotes repairs tissue. suggests biobased biodegradable significant scope clinical management.
