Abstract The exploitation of bio‐based materials derived from renewable resources represents a pivotal strategic approach in addressing environmental pollution and alleviating the scarcity fossil resources. 2,5‐Furandicarboxylic acid (FDCA) is most potential substitute for terephthalic acid. Lignin abundant aromatic biomass resource. However, preparation high‐performance lignin/FDCA‐based bio‐polyesters remains formidable challenge. Herein, multifunctional lignin‐modified polyester elastomer (LFPEe) designed using FDCA‐based oligomer (PPeF) lignin (AOH) as building blocks. LFPEe exhibits superior mechanical properties with optimum tensile strength, fracture strain, elastic recovery ratio up to 58.9 MPa, 610% 88.9%, respectively, attributing formation dual cross‐linking network nanophase separation structure. Furthermore, leveraging inherent characteristics lignin, demonstrates excellent light‐controlled shape memory UV shielding performance. This innovative work not only breaks performance dependence on high molecular weight but also highlights novel paradigm value‐added utilization sustainable bio‐polyesters.

A Highly Transparent, Underwater Self-Healing, Self-Adhesive, and Recyclable Supramolecular Eutectogel for Liquid Metal Encapsulation

ACS Materials Letters, Год журнала: 2023, Номер 5(10), С. 2621 - 2628

One-step preparation of supramolecular eutectogels (SEGs) with water resistance, transparency, underwater self-healing, self-adhesion, and full recyclability using a simple green process is intriguing but also challenging. Here, novel SEG prepared by in situ ring-opening polymerization thioctic acid (TA) polymerizable hydrophobic deep eutectic solvent (DES). Further depolymerization poly(TA) achieved synergistic interaction between the monomer DES components, resulting exhibiting highly optical extreme stretchability, recyclability. Moreover, multiple dynamic interactions enable self-healing self-adhesive processes to be easily realized even underwater. Given these comprehensive capabilities, SEGs are used as external encapsulation layers for liquid metals prepare stretchable composite wires electromyographic signal monitoring. The methodology provides new route recyclable integrated electronic components adhesives.

Lignocellulose-Based Optical Biofilter with High Near-Infrared Transmittance via Lignin Capturing–Fusing Approach

Research, Год журнала: 2023, Номер 6

Опубликована: Янв. 1, 2023

Near-infrared (NIR) transparent optical filters show great promise in night vision and receiving windows. However, NIR are generally prepared by laborious, environmentally unfriendly processes that involve metal oxides or petroleum-based polymers. We propose a lignin capturing-fusing approach to manufacturing biofilters based on molecular collaboration between cellulose from waste agricultural biomass. In this process, is captured via self-assembly network; then, the fused fill gaps hold fibers tightly. The resulting biofilter featured dense structure smooth surface with transmittance of ~90%, ultralow haze close 0%, strong ultraviolet-visible light blocking (~100% at 400 nm 57.58% 98.59% 550 nm). Further, has comprehensive stability, including water solvent thermal environmental stability. Because its unique properties, demonstrates potential applications region, such as an NIR-transmitting window, vision, privacy protection. These represent promising route produce starting lignocellulose biomass waste.
