Abstract Molecular dynamics (MD) simulations were carried out to explore the ideal structure design of graphene oxide (GO) modified by poly (dopamine) (PDA) which is more conducive to performances improvement of epoxy resin composites. The epoxy resin matrix was compounded with PDA-modified GO (PDA-GO) particles with different structures including the surface modification and the interlayer inserted modification. The interaction energy (Einter), molecular mobility (MSD), packing density (RDF), t...

Though being a promising anode material for sodium-ion batteries (SIBs), MoS2 with high theoretical capacity shows poor rate capability and rapid capacity decay, especially involving the conversion of MoS2 to Mo metal and Na2S. Here, we report all-in-one MoS2 nanosheets tailored by porous nitrogen-doped graphene (N-RGO) for the first time to achieve superior structural stability and high cycling reversibility of MoS2 in SIBs. The all-in-one MoS2 nanosheets possess desirable structural characteri...

Abstract Low-cost sodium ion batteries (SIBs) have shown hopeful perspective for large-scale energy storage systems. However, the development of carbon anode materials with high gravimetric and volumetric capacity is still a challenge. Herein, we propose a novel dense and N, P co-doped carbon derived from high density crosslinked bacterial cellulose (BC) with hexachlorocyclotriphosphazene (HCCP), which simultaneously combines high gravimetric and volumetric capacity. The as-prepared electrode de...

Abstract ZnO decorated ZnFe2O4 nanoparticles were synthesized and combined with reduced graphene oxide (rGO) to form ZnFe2O4@ZnO@rGO ternary hierarchical nanocomposites by a controllable method. The microstructure, morphology, and microwave absorption performance of the ZnFe2O4@ZnO@rGO nanocomposites were investigated in detail. The permittivity and permeability of the composites can be effectively regulated by controlling the content of ZnO and rGO to achieve a good impedance matching. Due to t...

Aromatic amine modified 3D porous graphene aerogel was prepared through chemical reduction and self-assembly of graphene oxide sheets in one step by using diaminodiphenylmethane (DDM) as a reducing agent, modifying agent, and curing agent. Subsequently, the DDM-modified graphene aerogel (DGA) was fully infiltrated with epoxy resin to obtain the DGA/epoxy composites. The abundant amine groups derived from DDM on the DGA can react with epoxy resin to strengthen the interfacial interaction, further...

Currently, the microwave absorption materials with high absorbing efficiency are in urgent need to reduce electromagnetic pollution. Herein, the ZnFe2O4@SiO2 core–shell microspheres were synthesized and combined with reduced graphene oxide (RGO) to form the ingenious hierarchical composites (ZnFe2O4@SiO2@RGO), which were used as wave absorbing functional nanofillers of semicrystalline polyvinylidene fluoride (PVDF) matrix. The microstructure and crystallization behavior of ZnFe2O4@SiO2@RGO/PVDF ...

Abstract The magnetic ZnFe2O4 nanoparticles were synthesized and combined with carbon nanotubes (CNTs) to form a unique tangled structure (ZnFe2O4@CNT), and then used as wave absorbing functional nanofillers of polyvinylidene fluoride (PVDF) matrix. The effects of ZnFe2O4@CNT functional nanofillers on the microstructure, crystallization behavior and electromagnetic wave absorption properties of PVDF were studied. The ZnFe2O4@CNT/PVDF composite membranes containing 7 wt% nanofillers presented an ...

Abstract In this study, the ultra-lightweight and robust three-dimensional graphene/polydopamine modified multiwalled carbon nanotube (MWCNT-PDA) hybrid aerogels were prepared via a viable green route and applied to highly efficient heavy metal ions adsorption. No additional reducing agents were required during the molding of the hybrid aerogel, thus greatly reducing the environment pollution emissions. The MWCNT-PDA in right amounts provided the hybrid aerogels with satisfying structure stabili...

Nowadays, physical absorption has become a feasible method offering an efficient and green route to remove organic pollutants from the industrial wastewater. Inspired by polydopamine (PDA) chemistry, one-dimensional PDA-functionalized multiwalled carbon nanotubes (MWCNT-PDA) were creatively introduced into graphene aerogel framework to synthesize a robust graphene/MWCNT-PDA composite aerogel (GCPCA). The whole forming process needed no additional reducing agents, significantly reducing the conta...
