“…This indicates that PBA had a significant inhibitory effect on the heat release of the melamine sponge. This fully demonstrated the conclusion that PBA, as previously confirmed in our prior work, [56] played a positive role in reducing heat release and smoke suppression. The pHRR of the individually carbonized melamine sponge (CMS) was 71.2 kW m −2 , representing a reduction of 64.1%.…”

“…This aligned with the conclusions drawn from Raman testing conducted on MS composite sponges before and after carbonization in Section 2.2, as well as the CCT testing on MS composite sponges in Section 2.7. On the other hand, as previously explored in our prior work, [56] the thermal degradation of MS composite sponges loaded with CoFe-PBA revealed the potential mutual promotion of Co and Fe, two variable-valence metal ions. This combination exhibited superior catalytic performance, generating bimetallic oxide CoFe 2 O 4 derived from the bimetallic organic framework.…”

Due to the difficulty of absorbing viscous crude oil, there is an urgent need for carbon sponges with excellent photothermal properties and oil‐water separation capabilities to reduce viscosity and facilitate oil absorption. However, the preparation of high‐temperature carbonization leads to poor mechanical properties, low absorption capacity, and stringent preparation conditions. To solve these challenges, a highly hydrophobic flame‐retardant melamine sponge (CPBA@CMS) is designed by assembling sponge at the interface of cobalt–iron Prussian blue (CoFe‐PBA) derived from metal–organic frameworks (MOFs) and conducting low‐temperature catalytic carbonization under nitrogen. The results demonstrate that CPBA@CMS exhibits excellent superhydrophobic properties (water contact angle = 169.7°) and oil absorption capacity (80.7–219.5 g g−1). Furthermore, CPBA@CMS displays remarkable photothermal effects and thermal conductivity, making it adaptable to various environmental conditions. It can rapidly rise to 141 °C under 1 kW m−2 solar irradiation, with the maximum oil absorption rate reaching 98% and the highest oil absorption capacity at 105.5 g g−1. Additionally, CPBA@CMS shows significant fire safety performance, reducing heat release rate by 84.2%, smoke factor by 97.5%, and CO release rate by 81.4%, respectively. It provides an efficient, safe, and sustainable practical solution for effectively addressing spills of crude oil.

“…17 However, pristine melamine sponges lack selectivity and require hydrophobic modification for effective oil/water separation. 18 Wang et al fabricated a superhydrophobic melamine sponge via a simple immersion drying process to produce ND-ODA@PDMS@ MS. 19 was obtained through coating of MIL-53(Fe) followed by 1dodecanethiol via polydopamine-assisted surface on the sponge. 20 While hydrophobic coatings have been explored for modifying melamine sponges, they often suffer from weak adhesion to the substrate, and their rough structure is highly fragile.…”

In addressing the pressing environmental challenges posed by frequent oil spills, this work presents a novel approach of synthesizing a superhydrophobic three-dimensional (3D) porous melamine sponge (MS). CuO and ZnO nanoparticles were grown on the MS via a hydrothermal method to create MS/CuO/ZnO with multiscale hierarchical nanostructures. The resulting material exhibited a stable water contact angle of 155°through various tests. MS/ CuO/ZnO demonstrated exceptional oil absorption capacities (40−145 g/g and 0.83−0.99 mL.cm −3 ), surpassing 98% efficiency in oil separation, and retained reusability for 10 cycles. Impressively, the sponge achieved successful separation of oil/water emulsions with a permeation flux of 14870 L m −2 h −1 . The composite sponge, distinguished by its high photodegradation ability, can degrade both waterand oil-targeted pollutants under visible light irradiation from light-emitting diode (LED). With its remarkable attributes including superior oil absorption, excellent oil/water separation, mechanical resistance, and excellent photocatalytic ability, it exhibits considerable potential for applications in both wastewater treatment and large-scale marine oil spill response. The easily prepared MS/CuO/ZnO emerges as a versatile solution capable of addressing pressing challenges and marking a significant leap toward sustainable and impactful environmental remediation.

“…[17] Superhydrophobic surfaces exhibit exceptionally high wettability, where water droplets barely come into contact with the surface and form spherical droplets that quickly roll off. This unique wetting behavior makes superhydrophobic surfaces highly promising in various fields, such as selfcleaning, [18][19][20][21][22][23] corrosion resistance, [24][25][26][27][28][29][30] anti-icing, [31][32][33][34][35][36][37][38] oil-water separation, [39][40][41][42][43][44][45][46][47] and microfluidic devices. [48][49][50][51][52][53] With the development of society and rapid technological advances, the superhydrophobic industry has become a globally strategic industry that profoundly affects daily life.…”
