Space exploration represents a critical frontier for advancing human knowledge and technology. However, the extreme space environment—characterized by wide temperature fluctuations, vacuum, radiation, atomic oxygen erosion, and micrometeoroid impacts—places exceptional demands on spacecraft materials. These conditions necessitate materials that are lightweight, thermally stable, radiation- and corrosion-resistant, and mechanically robust. High-performance fibers and fiber-reinforced composites have emerged as key candidates due to their excellent specific strength, stiffness, and tunable functionalities, finding broad use in spacecraft components, astronaut gear, and shielding systems. Despite growing interest in space-applied fiber materials, comprehensive reviews integrating material design principles, interface engineering strategies, and practical aerospace applications remain scarce. This review addresses that gap by systematically analyzing recent advances in high-performance fibers and composites for space use. It focuses on their performance under multifactorial space conditions and the impact of interfacial modification and matrix architectures on composite mechanics. Functional applications—such as atomic oxygen resistance, thermal protection systems, and electromagnetic shielding—are critically discussed, with an emphasis on limitations and challenges. Finally, we highlight future directions for material innovation, emphasizing the need for interdisciplinary approaches to advance next-generation aerospace fiber systems that not only meet demanding mission requirements but also support long-term sustainability for deep-space exploration.

Effective enhancement of the emission efficiency of tetraphenylporphyrin in solid state by tetraphenylethene modification

引用

Chinese Chemical Letters 2019年第1期30卷 143-148页

Tetraphenylporphyrin(TPP) is a typical red-emitting luminogen showing evident aggregation caused quenching(ACQ) effect. To enhance its emission efficiency in solid state, four tetraphenylethene(TPE)units were attached to the four meso-positions of TPP core via ester group through a facile and efficient route. The derived compound(4(TPE-COO)-TPP) emits red fluorescence(peak at 655 nm) with a good quantum efficiency(F) of 7.5%, which is much higher than that of TPP(Φ～ 0.1%). In molecular aggregate formed in tetrahydrofuran(THF) and water mixtures, 4(TPE-COO)-TPP has a relative high F of 12%. The evidently subdued ACQ behavior can be ascribed to the propeller shape and bulky size of the TPE units,which prevent the close packing and strong p-p interaction of TPP cores. The loose molecular packing and weak interchromophore interactions were validated by different characterization methods including UV-visible absorption, steady state and transient fluorescence spectroscope, X-ray diffraction and scanning electronic microscope observations. It is noted that 4(TPE-COO)-TPP has an emission efficiency of 14.4% in dilute THF solution. This is due to the conjugation break between the TPP and TPE moieties, the rotational and vibrational motions of the phenyl groups cannot quench the fluorescence of 4(TPE-COO)-TPP.

Long-term corrosion behaviors and wear behavior of Fe-based amorphous coatings in different humidity environments

Fe-based amorphous coatings (Fe-based AMCs) were successfully prepared on Q235 carbon steel by detonation spray under different spraying parameters. The corrosion and tribology behaviors of coatings were systematically tested. The droplets show disk-like morphology with the highest circularity and expansion factor, which is crucial to reduce the defects of coatings and to form fine-lamellar-structures coatings with dense microstructure. A higher incidence of porosity defects in the coating is associated with reduced long-term corrosion resistance. Moreover, the tribo-chemical reactions between Si 3 N 4 balls and water molecules play a significant role in wear behaviors for coating in different humidity conditions. The friction coefficient and wear rate of coatings decrease as the humidity conditions increase.

“One-Stone, Two-Birds”: Zinc-Rich Metal–Organic Frameworks as Precursors for High-Entropy Zn-Air Battery Electrocatalysts with Hierarchical Pore Structures

The active sites of inexpensive transition metal electrocatalysts are sparse and singular, thus high-entropy alloys composed of non-precious metals have attracted considerable attention due to their multi-component synergistic effects. However, the facile synthesis of high-entropy alloy composites remains a challenge. Herein, we report a “one-stone, two-birds” method utilizing zinc (Zn)-rich metal–organic frameworks as precursors, by virtue of the low boiling point of Zn (907 °C) and its high volatility in alloys, high-entropy alloy carbon nanocomposite with a layered pore structure was ultimately synthesized. The experimental results demonstrate that the volatilization of zinc can prevent metal agglomeration and contribute to the formation of uniformly dispersed high-entropy alloy nanoparticles at slower pyrolysis and cooling rates. Simultaneously, the volatilization of Zn plays a crucial role in creating the hierarchically porous structure. Compared to the zinc-free HEA/NC-1, the HEA/NC-5 derived from the precursor containing 0.8 Zn exhibit massive micropores and mesopores. The resulting nanocomposites represent a synergistic effect between highly dispersed metal catalytic centers and hierarchical adsorption sites, thus achieving excellent electrocatalytic oxygen reduction performance with low catalyst loading compared to commercial Pt/C. This convenient zinc-rich precursor method can be extended to the production of more high-entropy alloys and various application fields.

A Blinking Mesoporous TiO2−x Composed of Nanosized Anatase with Unusually Long-Lived Trapped Charge Carriers

A mesoporous TiO2−x material comprised of small, crystalline, vacancy-rich anatase nanoparticles (NPs) shows unique optical, thermal, and electronic properties. It is synthesized using polymer-derived mesoporous carbon (PDMC) as a template. The PDMC pores serve as physical barriers during the condensation and pyrolysis of a titania precursor, preventing the titania NPs from growing beyond 10 nm in size. Unlike most titania nanomaterials, during pyrolysis the NPs undergo no transition from the anatase to rutile phase and they become catalytically active reduced TiO2−x. When exposed to a slow electron beam, the NPs exhibit a charge/discharge behavior, lighting up and fading away for an average period of 15 s for an extended period of time. The NPs also show a 50 nm red-shift in their UV/Vis absorption and long-lived charge carriers (electrons and holes) at room temperature in the dark, even long after UV irradiation. The NPs as photocatalysts show a good activity for CO2 reduction. © 2020 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim
