Fire Intumescent, High-Temperature Resistant, Mechanically Flexible Graphene Oxide Network for Exceptional Fire Shielding and Ultra-Fast Fire Warning

Nano-Micro Letters, Journal Year: 2022, Volume and Issue: 14(1)

Published: April 6, 2022

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.

2D MXenes for Fire Retardancy and Fire‐Warning Applications: Promises and Prospects

Advanced Functional Materials, Journal Year: 2022, Volume and Issue: 33(9)

Published: Dec. 16, 2022

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.

Scalable, Robust, Low‐Cost, and Highly Thermally Conductive Anisotropic Nanocomposite Films for Safe and Efficient Thermal Management

Advanced Functional Materials, Journal Year: 2021, Volume and Issue: 32(8)

Published: Nov. 9, 2021

Abstract Recently, soaring developments in microelectronics raise an urgent demand for thermal management materials to tackle their “overheating” concerns. Polymer nanocomposites are promising candidates but often suffer from inability of mass production, high‐cost, poor mechanical robustness, and even flammability. Hence, it is desirable scalably fabricate low‐cost, robust polymeric that highly thermally conductive fire‐retardant ensure safe efficient management. Herein, the scalable production nacre‐like anisotropic nanocomposite films using layer‐by‐layer assembly phenylphosphonic acid@graphene nanoplatelets (PPA@GNPs)‐poly(vinyl alcohol) (PVA) layer GNPs layers, demonstrated. The PPA serves as interfacial modifiers fire retardants flammable PVA (film‐forming agent) (inexpensive nanofillers) via hydrogen‐bonding π–π stacking. resultant exhibits a high flexibility, tensile strength 259 MPa, ultrahigh in‐plane conductivity 82.4 W m ‐1 K , making effectively cool smartphone high‐power light emitting diode modules, outperforming commercial tinfoil counterparts. Moreover, as‐designed intrinsically can shield electromagnetic interference. This work offers general strategy holding great promise electronic, military, aerospace fields.
