Progress in Natural science:Materials International 2024年第2期34卷 354-361页

Controlled fabrication of materials by surface modification techniques has been a hot research topic. In this paper,one-dimensional(1D) core-shell structure Fe@Co nanowires(NWs) were successfully prepared by anchoring 0-dimensional(0D) Co nanoparticles on 1D Fe NWs based on the in situ reduction method. The electromagnetic parameters of the specimens at a filler mass fraction of 25 wt% were tested and the microwave loss mechanism was deeply analyzed. Binary magnetic metals in a core-shell structure have excellent multi-band microwave absorption capability(S-band, X-band and Ku-band). This is due to the heterogeneous interface and magnetic coupling effects tuning the dielectric and magnetic loss. This study offers a workable plan for creating effective multi-band magnetic metal-based microwave absorbers.

A novel high-efficient P/N/Si-containing APP-based flame retardant with a silane coupling agent in its molecular structure for epoxy resin

引用

Chinese Journal of Chemical engineering 2023年第3期55卷 137-147页

作者： Qiang Sun Jinlei Wang Xue Meng Jie Zhang Hong Yan College of Materials Science and Engineering Taiyuan University of TechnologyTaiyuan 030024China Key Laboratory of Interface Science and Engineering in Advanced Materials(Taiyuan University of Technology) Ministry of EducationTaiyuan 030024China

A flame retardant containing multiple antiflaming elements usually exhibits high-efficient flame retardancy. Here, a novel P/N/Si-containing ammonium polyphosphate derivative(APTES-APP) is synthesized from ammonium polyphosphate(APP) and silane coupling agent(3-aminopropyl)triethoxysilane(APTES)via cation exchange, which is quite different in the chemical structure from APTES-modified APP for retaining silicon hydroxyls. APTES-APP is highly efficient for the epoxy resin. 8%(mass) APTES-APP imparts excellent flame retardancy to the epoxy resin, with a V-0 rating at the UL-94 test(1.6 mm)and an LOI value of 26%(vol). The peak heat release rate and total smoke production of the flameretardant epoxy resin are decreased by 68.1% and 31.3%, respectively. The synergy of P/N/Si contributes to the well-expanded char residue with a strong and dense surface layer, which is a very good barrier against heat and mass transfer. Besides, there is no significant deterioration in the mechanical properties of flame-retardant epoxy resin thanks to silicon hydroxyls forming hydrogen bonds with epoxy molecules. Meanwhile, other molecules can be grafted onto APTES-APP via these silicon hydroxyls, if ***, this work has developed a new strategy for amino silane as flame retardants. In conjunction with a low-cost and simple preparation method, APTES-APP has a promising prospect in the high-performance flame-retardant epoxy.

Enhanced broadband near-infrared luminescence via phase engineering of Cr3+-doped crystals

引用

Progress in Natural science: Materials International 2025年第3期35卷 578-585页

作者： Liu, Shuaiyu Cui, Xiaoya Su, Ke Pan, Xin Wang, Yujia Yao, Lan Li, Qiaoling Mei, Lefu 100083 China Department of Materials Science and Engineering Southern University of Science and Technology Shenzhen518055 China State Key Laboratory of Physical Chemistry of Solid Surfaces Fujian Key Laboratory of Surface and Interface Engineering for High Performance Materials and College of Materials Xiamen University Xiamen China

As near-infrared spectroscopy technology is increasingly applied in fields such as biomedicine, food detection, and night vision, the demand for efficient near-infrared light sources is growing rapidly. However, traditional light sources, such as tungsten-halogen lamps and supercontinuum lasers, are hindered by low energy efficiency and bulky designs, limiting their suitability for advanced optical applications. Fluoride-based materials have attracted attention due to their low phonon energy and excellent optical transparency, making them promising candidates for next-generation light sources. Herein, cryolite-structured fluorides were synthesized to investigate their potential as efficient near-infrared emitters. Micron-sized Na3Sc1-xF6: xCr3+ and KyNa3-yScF6: 6 %Cr3+ crystals were prepared via a hydrothermal method. The influence of Cr3+ doping concentration and K+ substitution on crystal structure and luminescent performance were systematically explored. Cr3+ doping was found to induce lattice contraction and stabilize an octahedral crystal field, resulting in broadband near-infrared emission. Additionally, K+ substitution induces a phase transition, further enhancing luminescence and significantly extending fluorescence lifetimes. This work reveals the coupled effects of dopant concentration and structural modification in optimizing luminescent behavior. These findings provide valuable insights and theoretical guidance for the rational design and development of efficient near-infrared LED light sources, addressing essential challenges in advanced optical techniques. © 2025 Chinese Materials Research Society
