“…These introduced phosphate groups imparted a negatively charged nature to BP nanosheets, thus supporting scalable electrostatic-derived LbL assembly. [47] After being characterized by AFM, the detected thickness values of BP nanosheets were 6.247 and 2.809 nm, confirming the thin-layer structure (Figure 3). www.advancedsciencenews.com www.solar-rrl.com…”

Solar vapor generation is a promising and whole new branch of photothermal conversion for harvesting solar energy. In this work, a novel solar vapor generator based on black phosphorous (BP) nanosheets is designed for steam generation, desalination, as well as dye removal, using polyurethane (PU) foam as a supporting material. Employing electrostatic layer‐by‐layer assembly, BP nanosheets and chitosan (CS) are alternately deposited onto the skeleton of the PU foam. After the deposition of BP nanosheets, the hydrophilicity of the PU composite foam is obviously improved, thus facilitating the capillary effect. Even with a spot of BP nanosheets (lower than 5.0 wt%), the as‐fabricated PU@(sodium alginate, SA/BP)6 foam exhibits a surface temperature of ≈70.9 °C and an evaporation rate of 1.082 kg m−2 h−1 under 1 sun irradiation. Due to the protection effect of CS, the photothermal conversion performance and water evaporation rate do not deteriorate during ten cycles of reusing. In addition, the water evaporation performance of PU@(SA/BP)6 is also investigated under different conditions, including sun irradiation intensity, metal ions, and dye. In brief, employing a facile and eco‐friendly fabrication process, BP nanosheets are first applied to seawater desalination and pollution removal, presenting a tremendous potential for practical solar vapor generation.

“…In recent years, a large class of redoxactive biomolecules and biopolymers, with the quinone group as main redox center, has been studied as an energy storage material. [57][58][59][60][61][62][63] The quinone/hydroquinone (Q/QH 2 ) couple is an aromatic compounds with six carbon and two oxygen atoms that can be sequentially coupled with two protons, resulting in high charge capacity of 496 mAh g −1 . [24] Moreover, other cations such as lithium or sodium ions can coordinate to the negatively charged oxygen atoms upon electrochemical reduction of the carbonyl groups, and detach during the reverse oxidation, opening the possibility of using biomacromolecules with quinones for supercapacitors and lithium/sodium-ion batteries.…”

The development of energy storage devices with higher energy and power outputs, and long cycling stability is urgently required in the pursuit of the expanding challenges of electrical energy storage. The utilization of biologically renewable redox compounds holds a great potential in designing sustainable energy storage systems and contributes in reducing the dependence on fossil fuels for energy materials. Quinones are the principal redox centers in natural organic materials and play a key role as charge storage electrode materials because of their abundance, multiple forms and integration into the materials flow through the biosphere. Electrical energy storage devices and systems can be significantly improved by the combination of scalable quinone‐based biomaterials with good electronic conductors. This review uses recent examples to show how biopolymers are providing new directions in the development of renewable biohybrid electrodes for energy storage devices.

“…It is recognized that such structure could not create sufficient interfaces and provide continuous barrier to capture the reactive radicals and hinder the heat, oxygen, and mass transfer from outside during combustion even in homogeneous dispersion state. Therefore, we adopted a latex technique [40][41][42][43] in this study to prepare PDA/PS composites. We demonstrated that with the three-dimensional (3D) continuous structure of PDA layers inside matrix, the overall properties of PS were obviously improved by the addition of little amount of PDA.…”

Polymer materials are widely used in daily life, but the flammability of most polymers has greatly restricted their applications. The addition of flame retardants into polymer matrix to form composites is the most effective method to improve the flame retarding properties. Here, a novel flame retarding composite is reported from polydopamine (PDA) and polystyrene (PS) through a latex technique. To maximize the potential of PDA in improving the properties of composites, PDA layers are first coated on PS microspheres and then the PDA coated PS microspheres are hot pressed to afford PDA/PS composites. Morphological characterizations of the cross sections of composites and the char after burning demonstrate the formation of three‐dimensional continuous network of PDA layers inside PS matrix, while differential scanning calorimetry, thermogravimetric analysis, tensile test, and cone calorimeter test confirm the visibly enhanced thermal, mechanical, and flame retarding properties of composites as compared to neat PS. These improvements are attributed to the strong interfacial interactions between PDA and PS, physical barrier effect of continuous PDA layers, and good free‐radical scavenging ability of PDA. This work demonstrates the great potential of PDA as additive for green and facile construction of flame retarding composites. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47740.
