“…Eventually, combining the experimental data from ref. 18–20, the photothermal conversion efficiencies η (under 1 sun) of the photothermal materials equipped with anti-reflection structures can be obtained, respectively. Table 3 shows the comparison of reflectance and photothermal conversion efficiency of the three photothermal materials, where η 0 denotes the photothermal conversion efficiency (under 1 sun) of the bare photothermal material.…”

“…Moreover, the electric field distributions of the structures calculated by the finite difference time domain (FDTD) method are demonstrated. According to previous studies, devices based on three types of photothermal materials, PCCs, 18 PU/MCS, 19 and CFs/CNTs, 20 are designed in this work, successfully further improving their photothermal conversion efficiency. The proposed photothermal conversion devices not only exhibit excellent photothermal performance under full-spectrum (300–2500 nm) and omnidirectional solar irradiation, but also provide an effective approach to overcome the limitation in photothermal conversion efficiency caused by surface reflection in photothermal materials like carbon-based materials.…”

Using thermal storage materials with excellent thermal properties in the energy utilization system enables efficient use of renewable energy sources. Organic phase change materials (PCMs) have the advantages of high heat storage density, no corrosion, and low cost, but low thermal conductivity and insufficient heat transfer capacity have always been the bottlenecks in their application. In this paper, melamine foam@ reduction graphene oxide (MF@rGO) and carbon foam@ reduction graphene oxide (CF@rGO) composite foams with double carbon networks were prepared by self-assembly method and further employed in 1-octadecinal (OD) PCMs. The microstructure, chemical composition, phase change behavior, thermal conductivity, and photothermal conversion performance of MF@rGO/OD and CF@rGO/OD were studied in detail using SEM, FTIR, Raman DSC, and LFA. The melting and solidification enthalpies of CF@rGO/OD composite PCMs were 208.3 J/g and 191.4 J/g, respectively, its thermal conductivity increased to 1.54 W/m·K, which is 6.42 times that of pure OD. The porous structure and high thermal conductivity of the double carbon network substantially enhance the efficiency of energy storage and release in composite PCMs. CF@rGO/OD composite PCMs have excellent heat storage performance and heat transfer capacity, and a wide range of application prospects in the fields of low-temperature solar heat storage, precision instrument temperature control, and intelligent buildings.

Asymmetric hollow carbon (AHC) nanoparticles, celebrated for their distinctive external morphology, intricate internal topology, and exceptional carbon performance, are capturing significant attention. Nevertheless, exploring a universal emulsion assembling system to endow them with customizable architectures remains a formidable yet pending challenge. Interestingly, inspired by “plasticization”, a flowable colloidal polymer‐emulsion assembly strategy is first reported. It makes a striking debut of “dynamically growing‐like” AHC architectures, encompassing double‐headed mushroom, pleurotus eryngii, oyster mushroom, mushroom envelope, mushroom cap, and truffle‐shaped. This breakthrough creates an unprecedented “complete coverage” emulsion assembly mode, which surpasses the constraints of conventional “incomplete coverage” mode and infuses fresh vitality into the thriving nanoparticle‐library. More excitingly, it just is a brand‐new mechanism – the synergistic effect of plasticizing and swelling that flexibly manipulates the assembly between size‐variable emulsion droplet templates and flowable colloidal polymer, thereby successfully propelling the reversible architectural evolution. Remarkably, by skillfully integrating double‐headed mushroom‐shaped AHC nanoparticles with PEG and polyurethane sponge to engineer a composite adsorbent with reliable thermophysical property, it can offer a promising avenue for environmental governance. Generally, these cutting‐edge findings not only enrich the theory of emulsion assembly but also spark fresh inspiration for a vast spectrum of potential applications.
