Journal of Materials science & Technology 2022年第34期129卷 228-239页

The AlCoCrFeNi2.1 eutectic high-entropy alloy(EHEA) was prepared by selective laser melting(SLM), focusing on the anisotropy of microstructure and mechanical performance. The AlCoCrFeNi2.1 EHEA printed by SLM has face-centered cubic(FCC) and body-centered cubic(BCC)/B2 phases, and the FCC phase accumulates at the boundary of the molten pool. With the increase in volumetric energy density(VED), the content of the FCC phase parallel to the surface in the direction of the building increases from 30.9% to 41%. The X–Z plane mainly produces columnar crystals along the temperature gradient, while a large number of equiaxed crystals are produced in the X–Y direction. When the volume energy density is 157 k J/mol(VED 157), the average grain size is 1.33 μm for BCC and 1.14 μm for FCC, which is significantly smaller than other preparation methods. Due to defect distribution and size, the microhardness of the X–Y plane is generally higher than that of the X–Z plane, with maximum hardnesses of 660 HV and 655 HV, respectively, which is much higher than those of traditionally manufactured *** compression performance of SLM process AlCoCrFeNi2.1 EHEAs shows maximum yield strength of 1567 MPa, and the ultimate compressive strength can reach 3276 MPa.

基于应力发光的应力传感技术因其独特的机械-光子转换性质在柔性电子、结构健康诊断、生物力学工程和自供电显示等领域显示出巨大的潜力.然而,应力发光传感技术面临的一大挑战是当施加的机械载荷超过其强度极限时,具有典型无机@有机结构的应力发光传感材料将被损坏,从而降低其传感系统的可靠性和耐久性.本文提出了一种自修复方法,即通过构建聚硼硅氧烷/聚二甲基硅氧烷(PBS/PDMS)双网络结构来解决传感材料的失效问题.PBS网络中的动态硼酸酯键提供自愈合能力,化学交联的PDMS网络使应力发光材料保持良好的弹性和结构稳定性.这种双网络结构材料的力学性能和应力发光性能即使在遭受致命的断裂后也能得到有效恢复,室温下修复10分钟后拉伸强度恢复率为75%,机械-光子转换效率恢复率近100%.这种自修复的应力发光材料可以极大地促进应力发光技术在复杂、高强度和柔性应力传感中的应用.

Decorating hole transport material with −CF_(3) groups for highly efficient and stable perovskite solar cells

Journal of Energy Chemistry 2021年第11期30卷 523-531,I0012页

作者： Bin Li Yuan Cai Xia Tian Xiaozhong Liang Da Li Zheng Zhang Sijing Wang Kunpeng Guo Zhike Liu Ministry of Education Key Laboratory of Interface Science and Engineering in Advanced Materials Taiyuan University of TechnologyTaiyuanShanxi 030024China Key Laboratory of Applied Surface and Colloid Chemistry Ministry of EducationShaanxi Engineering Lab for Advanced Energy TechnologySchool of Materials Science and EngineeringShaanxi Normal UniversityXi’anShaanxi 710119China

The hole transport material (HTM) plays an extremely important role to determine the power conversion efficiency (PCE) and the stability of perovskite solar cells (PSCs). Herein, we report an effective strategy to improve the performance of HTMs by introducing −CF_(3) groups via the rational decorative mode. Upon direct attachment or nonconjugated alkoxyl bridging of −CF_(3) groups on the terminal diphenylamines, the resulting molecular HTMs, i.e., 2,7-BCzA4CF_(3) and 2,7-BCzA4OCCF_(3), show distinct properties. Compared with 2,7-BCzA4CF_(3), the nonconjugated alkoxyl bridging −CF_(3) group-based 2,7-BCzA4OCCF_(3) exhibits better thermal stability, hydrophobicity, and a dramatically upgraded hole mobility by 135.7-fold of magnitude to 1.71 × 10^(−4) cm^(2) V^(−1) S^(−1). The PSCs with 2,7-BCzA4OCCF_(3) as HTM exhibit an PCE of up to 20.53% and excellent long-term stability, maintaining 92.57% of their performance for 30 days in air with humidity of 30% without encapsulation. This work provides beneficial guidelines for the design of new HTMs for efficient and stable PSCs.
