Metal organic frameworks-derived iron carbide/ferroferric oxide/carbon/reduced graphene oxide nanocomposite with excellent electromagnetic wave absorption properties Compos. Commun. (IF 4.915) Pub Date : 2020-11-15 Weijie Li; Ruiwen Shu; Yue Wu; Jiabin Zhang
In this work, iron carbide/ferroferric oxide/carbon/reduced graphene oxide (Fe2C/Fe3O4/C/RGO) nanocomposite was fabricated through a facile solvothermal self-assembly and subsequent pyrolysis two-step strategy. Results of micromorphology and structure analysis showed that carbon frameworks displayed unique octahedral structure, and numerous Fe2C and Fe3O4 nanoparticles with an average size ca. 29 nm

In-situ confinement of ultrasmall SnO2 nanocrystals into redox-active polyimides for high‐rate and long-cycling anode materials Compos. Commun. (IF 4.915) Pub Date : 2020-11-10 Qian Liu; Zongying Xiao; Xun Cui; Qing Zhang; Yingkui Yang
SnO2 as a promising anode material possesses a high theoretical capacity and a safe lithiation potential; however, it suffers from low cycle stability and poor rate capability due to its nano-aggregation effect, structural instability, and sluggish electrode kinetics. Herein a one-pot hydrothermal process was developed to craft ultrasmall SnO2 nanocrystals uniformly encapsulated in the polyimide matrix

Ultralight graphene aerogel/PVDF composites for flexible piezoelectric nanogenerators Compos. Commun. (IF 4.915) Pub Date : 2020-10-24 Yiting Guo; Jie Xu; Wanli Wu; Shuhang Liu; Jia Zhao; Emilia Pawlikowska; Mikołaj Szafran; Feng Gao
Graphene aerogel/PVDF (GA/PVDF) composites with a three-dimensional structure were prepared using a vacuum-assisted impregnation process. The phase structure, morphology and piezoelectric properties have been systematically studied. The results show that GA/PVDF composites have good piezoelectric output characteristics and can provide corresponding feedback according to the magnitude and frequency

Enhancement of electromechanical properties in (0–3) lead-free ferroelectric nanocomposites with multiphase coexistence Compos. Commun. (IF 4.915) Pub Date : 2020-10-22 Le Van Lich; Takahiro Shimada; Takayuki Kitamura; Tinh Quoc Bui; Van-Hai Dinh
In this study, electromechanical responses of BiFeO3/BaTiO3 (BFO/BTO) (0–3) nanocomposites with different volume fractions of BFO nanoparticles are investigated using phase field model based on the Landau–Ginzburg theory. A rich phase coexistence, including tetragonal (T), orthorhombic (O), and rhombohedral (R) phases, is characteristically formed in the domain structure of the nanocomposite due to
