Abstract Most organic polymeric materials have high flammability, for which the large amounts of smoke, toxic gases, heat, and melt drips produced during their burning cause immeasurable damages to human life property every year. Despite some desirable results having been achieved by conventional flame‐retardant methods, application is encountering more difficulties with ever‐increasing requirements such as efficiency, great persistence, low release importantly not deteriorating or even enhancing overall properties polymers. Under condition, advanced methods developed in past years based on “all‐in‐one” intumescence, nanotechnology, situ reinforcement, intrinsic char formation, plasma treatment, biomimetic coatings, etc., provided potential solutions dilemma methods. This review briefly outlines development, application, problems including bulk‐additive, bulk‐copolymerization, surface focuses raise, The future development further discussed.

Abstract Polydimethylsiloxanes (PDMS) foam as one of next‐generation polymer materials shows poor surface adhesion and limited functionality, which greatly restricts its potential applications. Fabrication advanced PDMS with multiple functionalities remains a critical challenge. In this study, unprecedented self‐adhesive are reported worm‐like rough structure reactive groups for fabricating multifunctional nanocomposites decorated MXene/cellulose nanofiber (MXene/CNF) interconnected network by facile silicone foaming dip‐coating strategy followed silane modification. Interestingly, such produces strong interfacial the hybrid MXene/CNF nano‐coatings. Consequently, optimized have excellent super‐hydrophobicity (water contact angle ≈159 o ), tunable electrical conductivity (from 10 −8 to S m −1 stable compressive cyclic reliability in both wide‐temperature range −20 200 C) complex environments (acid, sodium, alkali conditions), outstanding flame resistance (LOI value >27% low smoke production rate), good thermal insulating performance reliable strain sensing various stress modes environmental conditions. It provides new route rational design development versatile multifunctionalities promising applications intelligent healthcare monitoring fire‐safe insulation.

Smart fire alarm sensor (FAS) materials with mechanically robust, excellent flame retardancy as well ultra-sensitive temperature-responsive capability are highly attractive platforms for safety application. However, most reported FAS can hardly provide sensitive, continuous and reliable signal output due to their undesirable temperature-responsive, flame-resistant mechanical performances. To overcome these hurdles, herein, we utilize the multi-amino molecule, named HCPA, that serve triple-roles including cross-linker, retardant reducing agent decorating graphene oxide (GO) sheets obtaining GO/HCPA hybrid networks. Benefiting from formation of multi-interactions in network, optimized network exhibits significant increment strength, e.g., tensile strength toughness increase ~ 2.3 5.7 times, respectively, compared control one. More importantly, based on P N doping promoting thermal reduction effect GO (withstanding 1200 °C attack), ultra-fast response time (~ 0.6 s) ultra-long alarming period (> 600 obtained, representing best comprehensive performance GO-based counterparts. Furthermore, fireproof coating is constructed applied polymer foam exhibited exceptional shielding performance. This work provides a new idea designing fabricating desirable coatings.

Abstract Frequent fire disasters have caused massive impacts to the environment, human beings, and economy. MXene has recently been intensively researched as potential flame retardants provide passive protection for other materials via its physical barrier catalyzing carbonization effects. In parallel, also demonstrated a great promise creating early warning sensors, which is an emerging field that active response through thermoelectric effect. This makes it possible integrate retardancy into one MXene‐based system on demand. However, fulfilling these promises needs more research. Herein, overview of flame‐retardant next‐generation smart materials/sensors based derivatives provided. study reviews their conceptual design, characterization, modification principles, performances, applications, mechanisms. A discussion challenges need be solved future practical applications opportunities presented.

A graphene oxide (GO)-based smart fire alarm sensor (FAS) has gained rapidly increasing research interest in safety fields recently. However, it still remains a huge challenge to obtain desirable GO-based FAS materials with integrated performances of mechanical flexibility/robustness, harsh environment-tolerance, high-temperature resistance, and reliable warning protection. In this work, based on bionic design, the supermolecule melamine diborate (M·2B) was combined GO nanosheets form supramolecular cross-linking nanosystems, corresponding GO-M·2B (GO/MB) hybrid papers nacre-like micro/nano structure were successfully fabricated via gel-dry method. The optimized GO/MB paper exhibits enhanced properties, e.g., tensile strength toughness up ∼122 MPa ∼1.72 MJ/m3, respectively, which is ∼3.5 ∼6.6 times higher than those paper. Besides, also shows excellent structural stability even under acid/alkaline solution immersion water bath ultrasonication conditions. Furthermore, due presence promoting reduction effect atom doping reactions network, resulting network displays exceptional sensitive response (∼0.72 s), ultralong alarming time (>1200 showing promising protection application prospects as shielding material comprehensive performances. Therefore, work provides inspiration for design fabrication high-performance that combine functions.
