引用

Energy & Environmental Materials 2024年第2期7卷 324-329页

作者： Jingwei Zhang Yuchao Wang Rongguo Song Zongkui Kou Daping He Hubei Engineering research center of RF-Microwave technology and Application School of Science Wuhan University of Technology Sanya science and Education innovation Park of Wuhan University of technology State Key Laboratory of Advanced technology for Materials Synthesis and Processing Wuhan University of Technology

Herein, we report the design, fabrication, and performance of two wireless energy harvesting devices based on highly flexible graphene macroscopic films（FGMFs）. We first demonstrate that benefiting from the high conductivity of up to 1 × 10～6S m-1and good resistive stability of FGMFs even under extensive bending, the FGMFs-based rectifying circuit（GRC）exhibits good flexibility and RF-to-DC efficiency of 53% at 2.1 GHz. Moreover,we further expand the application of FGMFs to a flexible wideband monopole rectenna and a 2.45 GHz wearable rectenna for harvesting wireless energy. The wideband rectenna at various bending conditions produces a maximum conversion efficiency of 52%, 46%, and 44% at the 5th Generation（5G） 2.1 GHz, Industrial Long-Term Evolution（LTE） 2.3 GHz, and Scientific Medical（ISM） 2.45 GHz, respectively. A 2.45 GHz GRC is optimized and integrated with an AMC-backed wearable antenna. The proposed 2.45 GHz wearable rectenna shows a maximum conversion efficiency of 55.7%. All the results indicate that the highly flexible graphene-film-based rectennas have great potential as a wireless power supplier for smart Internet of Things（Io T） applications.

The fabrication of ultrafine-grained microstructures(grain size below 1μm)in titanium alloys is beneficial for improving their mechanical properties at room temperature and medium tempera-tures(400-550°C).However,a long-standing challenge involves the low-cost manufacturing of bulk ultrafine-grained titanium *** this work,we developed a facile strategy through martensite de-composition at thermal-mechanical coupling conditions,to fabricate an equiaxed microstructure in a Ti6Al4Mo4Zr1W0.2Si model alloy with an averageαgrain size of 315±62 *** formation of the ultrafine-grained microstructure was because the lattice strain stored in the martensitic initial mi-crostructure enhanced the nucleation rate of dynamic recrystallization,meanwhile,the pinning role of martensite decomposition productsβand(Ti,Zr)_(5)Si_(3)phases suppressed grain coarsening at high *** to conventional(α+β)alloys,the tensile strength of this alloy improved by 20%-30%at both room temperature and 550°C,without decreasing its *** situ SEM observations revealed that the ultrafine-grained microstructure would not only suppress dislocation motions but also contribute to the homogenous deformation in the matrix of the material,therefore,it resulted in higher mechanical *** research results may be of great significance to the development of next-generation aviation titanium alloys.
