“…A systematic comparison of specific TCE values between our composite and other phase change composites was shown in Figure 3j and Table S3 (Supporting Information). [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39] The results confirmed the unique superiority of our method in constructing thermal conductive enhancement frameworks. Our 3D-BP/PEG composite revealed significantly enhanced specific TCE compared to composites with random and partially aligned filler distribution, thanks to the advancement of our optimized freeze-casting method.…”

Exploiting novel strategies for simultaneously harvesting ubiquitous, renewable, and easily accessible solar energy based on the photothermal effect, and efficiently storing the acquired thermal energy plays a vital role in revolutionizing the current fossil fuel‐dominating energy structure. Developing black phosphorene‐based phase‐change composites with optimized photothermal conversion efficiencyand high latent heat is the most promising way to achieve efficient solar energy harvesting and rapid thermal energy storage. However, exfoliating high‐quality black phosphorene nanosheets remains challenging, Furthermore, an efficient strategy that can construct the aligned black phosphorene frameworks to maximize thermal conductivity enhancement is still lacking. Herein, high‐quality black phosphorene nanosheets are prepared by an optimized exfoliating strategy. Meanwhile, by regulating the temperature gradient during freeze‐casting, the framework consisting of shipshape aligned black phosphorene at long‐range is successfully fabricated, improving the thermal conductivity of the poly(ethylene glycol) matrix up to 1.81 W m−1 K−1 at 20 vol% black phosphorene loading. The framework also endows the composite with excellent phase‐change material encapsulation capacity and high latent heat of 103.91 J g−1. It is envisioned that the work advances the paradigm of contrasting frameworks with nanosheets toward controllable structure thermal enhancement of the composites.

“…In this electrode material, the inner shell is comprised of n-docosane phase altered material embedded with silicon oxide, and the outer layer is coated with polyaniline/phosphorene hybrid structures that behave as a pseudocapacitive material. The electrode material reported in this work exhibits a distinctive blend of phosphorene and phase change material that demonstrates the prospective application of ultracapacitors at high temperatures [55].…”

“…Particularly, incorporating nanoscale inorganic particles into the polymeric shell commonly endows the MicroCapPCMs with good mechanical toughness and high thermal conductivity. To investigate the effect of hybrid shell on thermoregulation efficiency of PCMs, several works have been reported in recent years as follows: polyurea/Fe 3 O 4 nanoparticles, aminoplast/Ag nanoparticles, polystyrene/SiO 2 nanoparticles, melamine urea formaldehyde resin/iron nanoparticles, poly(methyl methacrylate)/SiO 2 nanoparticles, , polyaniline/SiO 2 , polyaniline/CNT, and poly(acrylic acid)/SiO 2 . All obtained results proved that the nanocomposite shells performed more efficiently than pure polymer shells.…”

The main purpose of this study is to develop papers with thermoregulation performance. The papers were made of nanofibrillated cellulose containing microencapsulated phase change materials (n-hexadecane), called MicroCapPCM. The papers can conserve actual solar energy and postpone warming of the hand-made house for around 30 min in comparison to bare roof or paper without MicroCapPCMs. The MicroCapPCMs were realized from oil-in-water Pickering emulsion templating, where emulsion droplets were stabilized by Fe3O4@GOQD@Gel nanoparticles, which are composed of Fe3O4 nanoparticles decorated with graphene oxide quantum dot and gelatin, respectively. The polymerization of oil phase containing hexadecane, styrene, and cross-linker gives microcapsules with a PCM core surrounded by a nanocomposite shell. The formed polymer/inorganic hybridization can improve the thermal conductivity of the shell to accelerate heat transfer. The successfully synthesized nanoparticles of 150 nm in size have both magnetic and pH-sensitive features showing well-stabilizing efficiency to form different droplet sizes with manipulation of nanoparticle content and pH. FE-SEM micrographs revealed a multinucleus morphology for the core and collapsed/wrinkled morphology for the surface of the MicroCapPCMs. The thermal and barrier properties of MicroCapPCMs were studied using DSC and TGA analyses. The results indicated that the encapsulation efficiency was varied from 97 to 22% with increasing styrene content in the oil phase. Finally, these temperature-regulating papers can be developed for potential applications such as intelligent textiles, ceiling or inner wall of greenhouses, and panels used in energy-efficient smart buildings.
