“…In order to make up for the adhesion between MXene and the foam, PDA, with powerful adhesion, a stable structure, and good biocompatibility, was chosen as a multifunctional platform to construct hierarchical nanohybrids. 21 Besides, the polymer polyaniline, which has unique features such as excellent light absorption ability and effective near-infrared (NIR) absorbance, 22 has become an ideal solarto-heat conversion material and can be doped with organic acids to play a more efficient application value. As an environmentally friendly, affordable, and accessible biomass organic acid, especially because of its special structure of inositol hexakisphosphate and a high phosphorus content of 28 wt %, phytic acid (PA) is gradually being extensively used in the fields of nanomaterial, flame retardancy, and anticorrosion.…”

“…Attracted by the property of absorbing sunlight and converting it into heat, more and more photothermal materials are being used for oil–water separation, especially for high-viscosity oil. It cannot be denied that MXene has been demonstrated superior internal solar-to-heat conversion efficiency (almost 100%) thanks to its localized surface plasma resonance (LSPR) effect. − Unfortunately, MXene suffered from irresistible aggregation and inhomogeneous dispersion on polymer substrates.

It remains a huge challenge to clean leaks of oil and various organic solvents quickly and efficiently, especially for special conditions such as high-viscosity oils, corrosion from acid/alkali solutions, high-temperature damage, and fire risk. The adsorbents with a three-dimensional porous structure and excellent resilience have been recognized as prospective candidates for dealing with oil−water separation problems. In this study, solar responsive and multifunctional polyurethane foams were successfully fabricated by compounding photothermal and hydrophobic components by both internal and external means. Due to the interface adhesion, polydopamine/MXene nanosheet/polyaniline/polydimethylsiloxane polyurethane (PMPP− PU) foams prepared by introducing PDA/MXene nanoparticles and phytic acid (PA)/PANI micronano coatings exhibited a high adsorption capacity up to 61.4 g/g for different kinds of low-viscosity organic solvents. Driven by 1 kW/m 2 illumination intensity, the adsorption capacity of PMPP−PU for high-viscosity oil increased to 29.4 g/g, realizing a 203% rise compared to pure PU. Also, the modified foams achieved rapid extrusion and cyclic adsorption of adsorbed solvents, and PMPP−PU showed an adsorption efficiency of close to 90% after 20 cycles. Besides, the prepared adsorbent foams remained persistent and maintained stable hydrophobicity under extreme environmental conditions and were not significantly damaged even by fire attack. This work presents a competitive strategy for the separation and recovery of low-viscosity organic solvents and high-viscosity oils.

“…[12] While polymers offer advantages such as processability, affordability, and lightweight, their intrinsic thermal conductivity is below 0.5 W mK −1 . [13,14] To enhance the thermal conductivity of polymers, various thermally conductive fillers such as boron nitride, [15] aluminum nitride, [16] graphene, [17] and carbon nanotube [18] are incorporated into the polymer matrix. The lightweight nature, high specific strength, and impressive high-temperature resistance of ANF composites have garnered significant attention.…”

A novel filler surface treatment is employed to produce thermally conductive composites using an aramid nanofiber (ANF) and pentaerythritol (PER) grafted onto the surface of graphite nanoplates (GnP). The resulting composite exhibits exceptional properties, including a high through‐plane thermal conductivity of 4 W mK−1, a high tensile strength of 163.58 MPa, and an improved flame retardancy. When the composite is applicated in central processing unit (CPU), the efficient thermal management performance is achieved with a decreased operating temperature of 12 °C. The ANF/GnP–PERANF composites are promising for enhancing thermal management in electric devices. The manufactured ANF composites will open new avenues for advancing the development of next‐generation thermal management systems.

This state‐of‐the‐art review is geared towards elucidating the molecular understanding of the carbon‐based flame‐retardant mechanisms for polymers via holistic characterisation combining detailed analytical assessments and computational material science. The use of carbon‐based flame retardants, which include graphite, graphene, carbon nanotubes (CNTs), carbon dots (CDs) and fullerenes, in their pure and functionalised forms are initially reviewed to evaluate their flame retardancy performance and to determine their elevation of the flammability resistance on various types of polymers. The early transition metal carbides such as MXenes, regarded as next generation carbon‐based flame retardants, are discussed with respect to their superior flame retardancy and multifunctional applications. At the core of this review is the utilisation of cutting‐edge molecular dynamics (MD) simulations which sets a precedence of an alternative bottom‐up approach to fill the knowledge gap through insights into the thermal resisting process of the carbon‐based flame retardants, such as the formation of carbonaceous char and intermediate chemical reactions offered by the unique carbon bonding arrangements and microscopic in‐situ architectures. Combining MD simulations with detailed experimental assessments and characterisation, a more targeted development as well as a systematic material synthesis framework can be realised for the future development of advanced flame‐retardant polymers.This article is protected by copyright.
