We report for the first time preparation of highly stable graphene (GE)-based nanofluids with ionic liquid as base fluids (ionic liquid-based (Ionanofluids)) without any surfactant and subsequent investigations on their thermal conductivity, specific heat, viscosity. The microstructure GE MWCNTs are observed by transmission electron microscope. Thermal conductivity (TC), viscosity these Ionanofluids were measured different weight fractions at varying temperatures, demonstrating that exhibit...

Highly thermally conductive, electrically insulating, and flexible nanocellulose composite films are crucially significant for the thermal management of next-generation green electronics. However, intrinsic hygroscopicity poses a daunting challenge to reliability structural stability electronic products. To address these issues, herein, dual bio-inspired design was innovatively introduced fabricate highly conductive superhydrophobic nanocellulose-based via vacuum-assisted self-assembly...

Abstract Polyimide microspheres were prepared via non‐aqueous emulsion polymerization by using pyromellitic dianhydride (PMDA) as anhydride monomer and 2,2‐bis(4‐(4‐aminophenoxy)phenyl)propane amine monomer. The polyimide well characterized Fourier transform infrared spectroscopy, SEM laser particle size analyzer. They spherical in shape monodisperse their was 31–33 μm. mixtures formed fillers composed of 4,4′‐oxydianiline (ODA) matrix investigated with regard to thermal properties,...

Phase change materials (PCMs) have been widely investigated for their ability to store enormous amounts of heat while maintaining ambient temperature during phase transition. In this study, microencapsulation PCMs (MEPCMs) were synthesized using the Pickering emulsion method address PCMs' defects, such as severe leakage paper, modified SiO2 nanoparticles are used stabilizers, and a polyurethane (PU) shell prepared from biobased soy polyols is encapsulate PCM ethyl palmitate successful...

Silicone elastomers, as good sealants and adhesives, have been widely applied in protective coatings, architectural decoration, electronic packaging, other fields. However, the traditional cross-linking of silicone elastomers is highly dependent on toxic catalysts or heavy metals, which may inevitably lead to severe environmental pollution. Moreover, most suffer from a poor adhesive performance. In this study, inspired by high adhesion properties mussels, an eco-friendly catalyst-free...

ABSTRACT Three kinds of 2‐ethyl‐4‐methylimidazole (EMI) derivatives ( N ‐acetyl EMI, ‐benzoyl and ‐benzenesulfonyl EMI) were synthesized through the reaction EMI with acetyl chloride, benzoyl benzenesulfonyl respectively. And structure was confirmed by Fourier transform infrared spectroscopy (FTIR) 1 H‐nuclear magnetic resonance H NMR) spectra. Furthermore, applied in diglycidyl ether bisphenol A epoxy resin (DGEBA) as latent curing agent. Differential scanning calorimeter (DSC) used to...

Abstract Phase change materials (PCMs) are usually used in latent thermal energy storage systems to address the mismatch between heat supply and demand, due their high density, high‐latent heat, almost constant temperature during phase process. However, low‐thermal conductivity of PCMs severe leakage limit practical applications. Thus, extensive efforts have been devoted constructing shape‐stabilized (SSPCMs). In this review, recent advances construction strategies applications SSPCMs...

Abstract Highly flame‐resistant epoxy composites have important application value in many industrial fields. Unfortunately, resins (EPs) are inherently flammable materials and exhibit great fire hazard. In this study, the commercially available 9,10‐dihydro‐9‐oxa‐10‐phosphaphenanthrene‐10‐oxide (DOPO) was chemically immobilized on surface of natural halloysite nanotubes (HNTs) via linkage vinyltrimethoxysilane to obtain a novel flame‐retardant VD@HNTs containing P/Si/Al elements. It found...

Overexposure to ultraviolet (UV) with high energy can not only hurt human skin but also accelerate the degradation of organic matter. Hence, preparation polymer‐based UV‐shielding nanocomposites has attracted substantial attention due low cost, easy processing and wide applications. Notably, highly efficient polymer are still hindered by agglomeration inorganic anti‐UV nanoparticles (Nps) in matrix narrow absorption range agents. To overcome aforementioned bottlenecks, surface engineering...
