Carbon fibers (CFs) are widely used in various cutting-edge fields, such as aerospace, military, automobiles, and sports, owing to their unique combination of excellent mechanical properties, good thermal stability, and lightweight. However, their inherent super-black appearance makes it difficult to satisfy the aesthetic/fashion requirements of the colorful world, and the flammability of CFs severely limits their practical utilization in high-temperature and other extreme environments. Herein, we fabricated full-color tunable colored CFs on a large-scale via atomic layer deposition, based on the monolayer film interference strategy. CFs exhibited brilliant colors and excellent environmental durability in extreme environments, such as intense ultraviolet (UV) irradiation, accelerated laundering, friction, high-temperature, and low-temperature treatments. Colored CFs also exhibited excellent fire-retardant performance that could withstand alcohol-lamp flame burning for 60 min. Our work provides insights into an innovative material/structural design that can help achieve rapid development of the CF industry and global carbon neutrality/sustainability. Graphical Abstract

Reusable absorbents with high absorption capacity, good selectivity, and low cost are highly demanded for efficient removal of oil spills and organic leakages from water. We discover that ZnO produced by atomic layer deposition (ALD) is hybridized with carbon moieties, and consequently exhibits an appreciable hydrophobicity. By taking this advantage, we develop a “dry” process to produce high-performance oil absorbents. Originally amphiphilic polymeric foams are directly turned into strongly hydrophobic oil absorbents simply by ALD of ZnO and exhibit excellent absorption capacity, selectivity and reusability. Such absorption capacities and reusability are better than most foam-based oil absorbents. Surprisingly, we find that ALD-deposited ZnO can reverse the wettability of polymeric foams depending on the foam porosities. This ALD-enabled surface functionalization is expected to find important applications in the synthesis of many other interfacial materials.

Aramid fiber holds a great potential application in harsh environments like defense and aerospace due to outstanding integrated properties, but it still falls short in poor UV resistance and surface inertness. It is an intriguing but challenging task to obtain high anti-UV efficiency for aramid fiber without compromising the mechanical characteristics. Herein, a uniform and thickness-controlled amorphous TiO 2 coating is chemically-bonded onto aramid fiber surfaces via a modified atomic layer deposition (mALD) strategy. Although mALD TiO 2 has an amorphous structure, its special chemical bonding state similar to LBL enables it to absorb UV light to a certain extent, but at the same time endows it with low photocatalytic activity. In contrast to bare aramid fiber with poor UV resistance and greatly suppressed mechanical performance, the modified aramid fibers with 1000 ALD cycles possesses well-preserved mechanical strength and flexibility. Moreover, they exhibit 54.08% retention of initial tenacity even exposure to UV irradiation with intensity of 4260 W/m 2 at high temperature ( > 200 °C) for 360 min (equals to continuous exposure to strong sunlight irradiation for about 7.5 years), simultaneously retain the excellent laundering durability and lustrousness, demonstrating a significant enhancement in anti-UV efficiency. Such highly anti-UV fibers fabricated by a facile mALD strategy provide a new perspective on designing multifunctional fibers and devices for future innovative applications.

Surface modification via atomic layer deposition (ALD) of metal oxides ( ex. , TiO 2 ) has been suggested as an effective strategy to enhance the electrochemical performance of high-specific-capacity electrode materials. Herein, we study the lithium storage behavior of TiO 2 coated CoSe 2 nanorods (TiO 2 @CoSe 2 ), in which a thin layer of TiO 2 shell is deposited via a conventional ALD method. The effects of the TiO 2 deposition on the structural and electrochemical characteristics of the CoSe 2 nanorods are systematically investigated. When applied as anodes for LIBs , the TiO 2 @CoSe 2 electrode displays much enhanced lithium storage performance including higher specific capacity, better cycle stability and rate capability, delivering a discharge capacity of 999.2 mA h/g after 300 cycles at 200 mA/g and an exceptional capacity of 723.7 mA h/g after 430 cycles even at high current density of 500 mA/g, which is much higher than that of the bare CoSe 2 electrode (only 145.4 mA h/g after 220 cycles at 200 mA/g).

Graphical Ultrafine Au nanoparticles with a narrowly distributed size were synthesized on TiO 2 by ALD using Me 2 Au(acac) and ozone as the precursor reactants. Nano-sized gold particles have shown unique merits in the field of catalysis, sensing and imaging, whereas their controllable synthesis with sub-nanometer size and narrow distribution on a support still remains a challenge. Herein, we developed a facile and controllable process of atomic layer deposition (ALD) using dimethyl(acetylacetonate)gold (Me 2 Au(acac)) and ozone as the precursor reactants to directly synthesize ultrafine Au nanoparticles on titania support. The size of Au nanoparticles could be precisely controlled via the modulation of depositing temperature and the counter reactant. Additionally, the dispersion of Au nanoparticles on the support is decreased by pre-calcining TiO 2 in air, which is due to the decreased surface hydroxyls concentration on support, leading to less adsorption sites of gold precursor. Moreover, we demonstrated that Au nanoparticles prepared by this method on TiO 2 could function as an effective co-catalyst for photocatalytic hydrogen evolution reaction.

Vectran fabrics are widely employed as the key material for the manufacturing of stratospheric airship. Nonetheless, Vectran faber would decompose due to the UV aging during the prolonged flying process. Herein, atomic layer deposition (ALD) technology was introduced to coat TiO 2 nanolayers on the surface of Vectran fabrics. Titanium isopropoxide liquid was employed as the Ti source precursor throughout the deposition process. Compared with sol-gel vacuum infiltration technic, ALD modified Vectran yarns possessed higher surface uniformity, better UV blocking performance and lower density. Notably, thickness of the TiO 2 nanocoating prepared through the ALD method was adjustable, which can optimize the UV resistance of Vectran yarn without significantly affect its density. Additionally, the nanolayer interface can induce structural coloration on the Vectran strand via diffraction phenomena. These outstanding merits endow ALD technic a promising choice to modify the surface of Vectran fiber used as the skin of stratospheric airships.

As a luxurious textile raw material, silk fiber (SF) and its products are widely favored by consumers because of their elegant appearance and excellent comfort. However, their flammability causes potential fire risks and hazards in daily fires and has gained significant attention in recent years. In this work, an ultrathin and uniform TiO 2 , Al 2 O 3 , and ZnO nanofilms with thicknesses of 1 ∼ 200 nm (less than one in a hundred of SF diameter) were deposited on the surface of a silk fabric (SFR) by atomic layer deposition (ALD). By tuning the types of metal oxides and nanofilm thickness, the modified SFR quickly self-extinguished, and its pristine weave was completely preserved after exposure to a flame in a torch burn test, representing superior performance compared to numerous conventional coating technologies reported with higher loadings. An expanded charcoal residue formed on the surface of the modified SFR, acting as a physical barrier that enhanced flame retardancy. Furthermore, the modified SFR showed excellent laundering durability, which helps improve the service life of the fabric. Most importantly, the nanofilms had a negligible impact on the intrinsic comfort and other comprehensive properties of the silk.

Coatings play a crucial role in minimizing eddy current loss in soft magnetic composites (SMCs). The powder atomic layer deposition (PALD) technique was utilized to coat Fe–Ni–Mo soft magnetic powder in this study. The Al 2 O 3 coating fabricated via PALD enhanced corrosion resistance and reduced core loss in SMCs. Additional deposition cycles increased the resistivity of the Fe–Ni–Mo powder and the corrosion resistance of the Fe–Ni–Mo SMCs, indicating that the density and integrity of the amorphous Al 2 O 3 coating were enhanced. Thinner coatings (20 cycles) exhibited anodic passivation in corrosion, which was attributed to insufficient density. Nevertheless, an excessively thick coating (100 cycles) resulted in a decrease in effective permeability and an increase in hysteresis loss. The fabricated Fe–Ni–Mo SMCs (50 cycles) demonstrated a core loss of 603.1 mW/cm 3 at 100 kHz/100 mT, coupled with an effective permeability of 108.5 and a Q value of 97.8 at 100 kHz.

The incorporation of metal–organic frameworks onto conductive substrates demonstrates considerable potential in applications related to the hydrogen evolution reaction. In this work, we present a streamlined synthesis approach involving atomic layer deposition pretreatment to facilitate the controlled growth of Cu-BDC particles on a conductive Nafion film. This methodology preserves a substantial loading of Cu-BDC with a hierarchically porous structure, accompanied by a notable surface area of 547 m2 g–1. The composite is subsequently utilized as an electrocatalyst for hydrogen generation in an alkane electrolyte. The structural advances in the composite result in a superior electrochemical hydrogen production efficiency with a low overpotential of 84 mV and a low Tafel slope of 58 mV dec–1 in 1.0 M NaOH. Notably, the composite showed good cycling performance during the 18 h test with 2000 cycles. This research introduces a design of a catalyst electrode with promising implications for the hydrogen production industry.

Aramid fibers (AFs) are widely applied as structural material, cordage, and versatile protection in many harsh environments, including space and deep sea. However, intense ultraviolet (UV)/ irradiation, high/low temperatures, and/or chemical solvent with strong acid/alkali/corrosion feature seriously affect their mechanical properties, thus severely shorten the life cycle of AF-based products. Inspiration by the principle of multiple refractions and partly reflections, an innovative strategy by depositing of laminated Al 2 O 3 /TiO 2 composite onto the surface of poly(m-phenylene isophthalamide) (PMIA) via atomic layer deposition (ALD) technique was presented. The tenacity of ALD-coated PMIA only decreases by ∼ 8 %, and the yellowness index (YI) only increasing to 129.24 %, far lower than 321.63 % of pristine PMIA fabric under the combination of intense UV irradiation (4260 W/m 2 ) and high temperature (200 °C + ) for 6 h, which equals to continuous strong sunlight exposure for approximately 7.5 years. Meanwhile, ultraviolet protection factor (UPF) value increased to 126.4, which is double that of the pristine PMIA fabric, exhibiting an impressive UV-resistance property. Furthermore, the ALD-coated PMIAs also shows a significant enhancement in both chemical and thermal stabilities. In all, this work not only forge a new route for the functionalization of fibrous materials, but also exhibits great promise for next generation advanced composite material and cutting-edge equipment in harsh environment.

The friction influence of 2-D molybdenum disulfide (MoS 2 ) films deposited on different substrates (Si, SiO 2 and Al 2 O 3 ) by atomic layer deposition (ALD) has been investigated. All of the three substrates showed a trend of decreasing friction with increasing number of layers of MoS 2 , but the friction leveled off for more than 6 layers samples. Comparing these 2-D MoS 2 films with each other, MoS 2 on the Al 2 O 3 possesses the lowest friction, while MoS 2 on the Si possesses the highest one, owing to effect of substrate on the specific self-limiting reaction in ALD process. At the same time, the friction of the monolayer MoS 2 is strongest affected by sulfur deficient. As the number of layers increases, the influence of the substrate on the friction of MoS 2 can be approximately characterized by the work of adhesion. Greater work of adhesion corresponds to a higher friction force. When the thickness is more than 6 layers, the substrate effect disappears gradually. Moreover, the friction of 2-D MoS 2 could be controlled near linearly by changing plasma treatment time within the range from 1 to 20 s, which suggests a possible way for the friction control of 2-D MoS 2 on different substrate quasi-qualitatively or even qualitatively.

As a member of the two-dimensional transition metal dichalcogenide family, rhenium disulfide (ReS2) is a highly competitive favorite in the field of photoelectric sensors. Nevertheless, the rapid recombination of electron–hole pairs and poor electronic transmission capacity of pure ReS2 limit its wider applications. As a new attempt to optimize its inherent structure and challenge its competency boundary, in this work, a bimetallic co-chamber feeding atomic layer deposition with a precise dose regulation strategy has been used to fabricate ReS2 nanotubes (ReS2-NTs) and MoS2–ReS2 heterojunction nanotubes (MoS2–ReS2-HNTs) based on the anodic aluminum oxide template sacrifice method for the first time. These obtained NTs have at least two advantages: they have a controllable diameter (40–500 nm), definite wall thickness (1 layer to 10 layers), and desirable Mo-to-Re ratio (0 to 90%), and their electron-transfer capacity and photocurrent response can be effectively enhanced by the incorporated Mo atoms. Further experiments indicated that MoS2–ReS2-HNTs with a real Mo-to-Re ratio of 31.0% exhibits the best photocurrent response performance, by which the ultrasensitive detection of cancer-related miRNA-155 with a linear range of 10 aM to 1 nM and a detection limit of 1.8 aM is achieved.
