Fire‐retardant and high‐strength polymeric materials enabled by supramolecular aggregates

Aggregate, Journal Year: 2024, Volume and Issue: 5(2)

Published: Jan. 4, 2024

Abstract High‐performance polymers have proliferated in modern society across a variety of industries because their low density, good chemical stability, and superior mechanical properties. However, while are widely applied, frequent fire disasters induced by intrinsic flammability caused massive impacts on human beings, the economy, environment. Supramolecular chemistry has recently been intensively researched to provide retardancy for via physical barrier char‐catalyzing effects supramolecular aggregates. In parallel, noncovalent interactions between polymer chains, such as hydrogen bonding, π–π interactions, metal–ligand coordination, synergistic can endow matrix with enhanced strength. This makes it possible integrate physical–chemical properties into one aggregate‐based high‐performance polymeric system demand. fulfilling these promises needs more research. Here, we an overview latest research advances fire‐retardant high‐strength materials based structures work reviews conceptual design, characterization, modification principles, performances, applications, mechanisms. Finally, development challenges perspectives future also discussed.

Mussel‐Inspired, Self‐Healing, Highly Effective Fully Polymeric Fire‐Retardant Coatings Enabled by Group Synergy

Advanced Materials, Journal Year: 2024, Volume and Issue: 36(44)

Published: Aug. 30, 2024

Fire-retardant coatings represent a universal cost-effective approach to providing fire protection for various substrates without compromising substrates' bulk properties. However, it has been attractive yet highly challenging create waterborne polymeric fire-retardant combining high-efficiency, generally strong adhesion, and self-repairability due lack of rational design principles. Inspired by mussel's unique adhesive, self-healing, char-forming mechanisms, herein, "group synergy" strategy is proposed realize the combination high efficiency in fully coating via multiple synergies between catechol, phosphonic, hydroxyethyl groups. As-created exhibits rapid room-temperature self-healing ability adhesion (non)polar dynamic non-covalent interactions enabled these Because functional groups enable formation robust structurally intact slightly expanded char layer upon exposure flame, 200 µm-thick such can make extremely flammable polystyrene foam very difficult ignite self-extinguishing, which far outperforms previous strategies. Moreover, this provide exceptional variety from polymer foams, timber, fabric steel. This work presents promising material principle next-generation sustainable high-performance general protection.

Bioinspired Mechanically Robust and Recyclable Hydrogel Microfibers Based on Hydrogen‐Bond Nanoclusters

Advanced Science, Journal Year: 2024, Volume and Issue: 11(23)

Published: April 15, 2024

Abstract Mechanically robust hydrogel fibers have demonstrated great potential in energy dissipation and shock‐absorbing applications. However, developing such materials that are recyclable, energy‐efficient, environmentally friendly remains an enormous challenge. Herein, inspired by spider silk, a continuous scalable method is introduced for spinning polyacrylamide microfiber with hierarchical sheath‐core structure under ambient conditions. Applying pre‐stretch twist the as‐spun microfibers results tensile strength of 525 MPa, toughness 385 MJ m −3 , damping capacity 99%, which attributed to reinforcement hydrogen‐bond nanoclusters within matrix. Moreover, it maintains both structural mechanical stability several days, can be directly dissolved water, providing sustainable dope re‐spinning into new microfibers. This work provides strategy recyclable hydrogel‐based fibrous materials.
