A coating with both anti-corrosion function and antibacterial ability was developed by means of urea-formaldehyde resin self-assembly. The self-assembled urea-formaldehyde microspheres on basalt facilitate the formation of a good adhesion filler/coating matrix interface, which effectively promoted the corrosion resistance of the coating. Serving degradation of chemical bonds in urea-formaldehyde cause release of formaldehyde as a bactericide on the EBUF coating, thus imparting antimicrobial activity against PAO1 , B.l , and SRB , as observed. The EBUF composite coating thus exhibits combined anticorrosion and antimicrobial activity, suitable for corrosion control in severe environments.

The contamination of water with hexavalent chromium (Cr(VI)) poses a significant environmental and health threat. Basalt fiber (BF) is a high-strength, high-temperature-resistant, corrosion-resistant, and eco-friendly inorganic fiber material that shows promise for addressing such contamination. However, a key challenge lies in how to effectively modify its surface functionality and enhance the overall performance of fiber composites to improve adsorption efficiency, especially in large-scale applications. In this study, we present a scalable fabrication method for graphene-basal composite material using a layer-by-layer deposition technique. This process enables the mass production of highly efficient Cr(VI) adsorbents. It exhibited a Cr(VI) removal rate of up to 97.9 % within 2 h, making it a promising candidate for efficient Cr(VI) adsorption. The composite material, integrating the high surface area of graphene with the mechanical strength and chemical stability of basalt, exhibits superior adsorption capacity and reusability in removing Cr(VI) from contaminated water. Density functional theory (DFT) calculations indicated that the synergistic interaction between GO and BF enhanced both the physical and chemical adsorption of Cr(VI), facilitating its removal. Batch experiments demonstrate that the composite achieves rapid and efficient Cr(VI) removal across a wide range of pH levels and initial concentrations. The simple and scalable fabrication process highlights the potential for practical applications in large-scale water treatment. Furthermore, this study provides insight into the mechanisms underlying the adsorption process, offering a sustainable, rapid, and cost-effective solution to heavy metal pollution in environmental water bodies.

This study addresses critical challenges associated with fiber-supported photocatalysts, including complex preparation procedures, degradation of mechanical properties, low ion utilization efficiency in precursor solutions, and weak interactions between the photocatalyst and the fiber. To address these challenges, K + /Na + ion exchange coupled with solvothermal synthesis was employed to modify basalt fiber cloth (BFc) by synthesizing BiOI. The mechanical properties of BFc were significantly enhanced through the ion exchange process. The key findings include the synthesis of BiOI nanoflower spheres (0.6–1.2 μm) on BFc, which are smaller than those reported in previous studies (2–9 μm). BiOI forms stable Bi-O-Si linkages with BFc, thereby resulting in a highly stable composite. The BiOI/BFc composite exhibited increases of 12.59% in tensile strength and 20.88% in elastic modulus compared to pure BFc. Moreover, the composite demonstrated exceptional photocatalytic performance and long-term stability in RhB degradation, with the reaction rate constant (k) increasing as the temperature rose. The primary active species involved in the reaction were •O 2 − and h + . This study presents a novel approach for the preparation of BFc-based composites with enhanced performance.

Basalt fiber is one of high performance inorganic fibers. As a promising textile material, basalt fiber has to be equipped with a coating to avoid abrasion during the handling and textile process. Starch phosphate sizing agent with different content of phosphate groups were prepared and coated on basalt fiber surface to improve its mechanical properties. The results showed that the fiber surface was successfully covered by a uniform and compact layer and modified by starch phosphates. The breaking force of the optimal sized fiber can be 47.8% higher than that of nonsized fiber, and the breaking elongation was also 12.6% higher than that of the original fiber.

Inspired by the strong adhesion of mussels, basalt fibers (BFs) were modified with polydopamine and then composited with nylon 6. The effect of polydopamine content on the interfacial interactions and mechanical properties of the composites was investigated. In addition, silica nanoparticles were grown on the surface of polydopamine-modified BFs to investigate the synergistic effect. The study revealed that the mechanical properties of the composites based on polydopamine-modified BF were gradually enhanced with the increase of the dopamine coverage concentration, and gradually decreased after reaching the peak. 0.5 g/L concentration of dopamine solution modified BFs showed the best enhancement effect on nylon 6, and its tensile strength could reach 133.1 MPa, which was 28.5% higher than that of the unmodified composites. The tensile strength of the composites modified with both dopamine and silica nanoparticles reached 157 MPa, which was 51.7% higher than that of the unmodified composites. In addition, scanning electron microscope images of fracture sections confirmed the strong interfacial interaction between BF and PA6. Highlights The surface roughness of BF was increased by nano-SiO 2 . Hydrogen bonding was formed between PDA and PA6. Physical interlock was formed between nano-SiO 2 and PA6. Tensile strength increased by 51.7% with both nano-SiO 2 and PDA. Stronger interfacial interaction leads to higher thermal stability.

Basalt fiber is widely applied in composite materials. Recent years, it has a new application in filter bags. But commercial sizing agent always decomposes at 300 °C, which limits the application of basalt fiber above 300 °C. To solve this problem, in this study, a water-soluble polysiloxane sizing agent was synthesized and used to coat basalt fiber to improve its heat resistance . TG-DSC results showed the polysiloxanes starts to decompose at 370 °C. SEM and AFM results indicated that the surface of the fiber was wrapped by an organic coating . Abrasion tests showed friction factors of basalt fibers were decreased by the coating. XPS study showed there was a chemical connection between the layer and surface. Results of contact angles showed the surface energies of the fiber have increased after coated. Mechanical tests showed the breaking force of the coated basalt fiber could be maintained above 76% at 300 °C, which was 3.8 times that of unsized fiber, and kept above 49% at 400 °C, which was 2.4 times that of unsized fiber.

Successful integration of ideal amounts of porous materials onto the fibrous substrate requires a subtle balance between the loading ratio and structural robustness. In this study, zeolitic imidazolate framework-8 (ZIF-8) crystals could be controllably coupled on the surface of the fibrous basalt fiber felt via a mild synthetic route with a combination of biomimetic mineralization and layer-by-layer growth. Specifically, by regulating the deposition time and the number of growth cycles, a high loading ratio of 47.1% for ZIF-8 could be achieved without sacrificing the strength of the substrate. The remarkable stability of the composite against varied environmental factors such as high temperature, humidity, and solution corrosion circumstances were confirmed which could be attributable to the ultra-stability of single components and strong bonding between them. The high-quality loadings of the ZIF-8 ensured the fiber composite with abundant porosity, featuring a considerable specific surface area of 822 m 2 /g, which made it a promising candidate as a high-effective pollutant adsorbent. The maximum iodine vapor capacity of the optimal sample could reach 3614 mg/g. The mechanism of iodine adsorption was further explored in kinetics and thermodynamics aspects. This study is projected to overcome the defect of the MOF powder in the real application and further outline a facile method for the construction of MOF-fiber composite in a controllable manner.

For adapting to the working condition of high-speed rail grinding with strong impact and heat, the basalt fibers reinforced grindstones (BFRGs) were prepared. Their performances were evaluated from three aspects, including the mechanical properties of grindstones themselves, grinding behavior and grinding quality. The results show that basalt fibers significantly improve the strength of grindstone, which has reached up to 78.3 MPa increased by 25.5%. The heat effect of BFRGs drops as low as 159 ℃. After grinding, the thickness of white etching layer is reduced to 0.5 µm. The content of basalt fiber at 6.7 wt% in resin can achieve the optimum comprehensive performance, mainly depending on the advantages in blocking effect and rolling bearing of basalt fibers.

Benzoxazine containing phthalonitrile, as one of the most advanced high performance thermosetting resin, has gained a lot of attention in the last decades. Indeed, the combination of the thermally activated ring-opening polymerization of the benzoxazine and the cyano addition reaction of the phthalonitrile allows the development of robust polymeric networks. Following this path, a renewable natural resource, vanillin, was used to develop a new benzoxazine containing phthalonitrile thermosetting system. The newly developed monomers present the advantage of a simple synthesis process along with an autocatalytic polymerization mechanism. The molecular structures of the synthesized monomers were characterized by Fourier transform infrared spectroscopy (FTIR) and proton nuclear magnetic resonance spectroscopy (1H NMR). The curing behavior was assessed by differential scanning calorimetry (DSC). The newly developed monomers were then reinforced with a silane surface modified basalt fibers (BFs) allowing the preparation of a high performance green composite. The silane surface modification of the BFs was confirmed by FTIR and thermogravimetric analysis (TGA). The tensile and bending tests highlighted the remarkable mechanical properties of the developed green composite. Finally, the scanning electron microscopy (SEM) was used to study the mechanism of stress transfer between the matrix and the fillers. Overall, the developed green composite can be seen as a promising substitute to composites made from glass fibers.

In this study, basalt scales were activated by air plasma and were subsequently deposited with cerium dioxide nanoparticles to obtain CeO 2 -modified basalts (CB). Inspired by mussel biomimetics, polydopamine (PDA) and 3-glycidoxypropyltrimethoxysilane were further employed to modify the properties of CB to obtain functionalized basalt scales (CBD). This treatment greatly increased the interfacial compatibility between inorganic fillers and epoxy resin. At the same time, PDA can form chelates with iron ions in the anodic area to prevent further corrosion. Tensile, water absorption, and electrochemical impedance spectrum measurements showed that incorporating CBD into epoxy resins resulted in the composite coatings with higher mechanical properties, water penetration resistance, corrosion resistance, and lower wetting properties.

Developing efficient catalysts is crucial for the chemical utilization of CO2, which would be conducive to solving both environmental issues and the resource crisis. In this work, a basalt fiber (BF)-supported CuNi catalyst was constructed for the conversion of CO2 and methanol to dimethyl carbonate (DMC). In order to optimize the surface properties of BF, the pristine BF (BF-U) was modified by HCl (BF-H) and NaOH (BF-N) solutions. The influence of the BF surface properties on the physicochemical state of CuNi and the catalytic performance of the supported CuNi/BF catalysts was systematically investigated. The results showed that the CuNi/BF-N monolithic catalyst had the best activity, and the yield of DMC reached 12.9%. SEM, XRD, and XPS characterizations exhibited that the CuNi nanoalloy particles were uniformly distributed on BF-N and possessed high Cu0/1+ and Ni0 contents. This contributed to the abundant CO2 adsorption sites, as evidenced by CO2-TPD, especially for the medium-strength CO2 adsorption sites, which was responsible for the superior catalytic activity. This study provides an efficient catalyst for the synthesis of DMC from CO2 and methanol and can serve as a reference for industrial catalyst design.

Basalt fiber is commonly regarded as an alkaline corrosion-resistant material, capable of being transformed into various products (such as basalt fiber roving, chopped yarn and composite reinforcement). However, the main composition of the basalt fiber network skeleton consists of Si ∼ O bonds, which can still react with ∼OH in the alkaline environment. Nevertheless, there are differing viewpoints on the alkaline corrosion of basalt fibers within literatures. Therefore, this study aims to select three representative types of basalt fibers and compare them with two alkali-resistant glass fibers and one regular glass fiber. The attenuation mechanism of basalt fibers were investigated through orthogonal experiments, practical application scenarios and microscopic characterization methods. Additionally, we employed the Weibull model to analyze failure probabilities after erosion on basalt fibers while also applying a machine learning artificial neural network (ANN) model for predicting their alkali resistance. The results indicated that the tensile strength of basalt fiber tended to decrease and the alkali resistance of basalt fiber between alkali-resistant glass fiber and regular glass fiber in four alkaline solutions. The Weibull model also confirms that erosion increases failure probability of basalt fiber and glass fiber. Moreover, Si ∼ O, which forms the network reacted with OH-, resulting in a reduction in surface Si and Al elements content. It became possible to predict the alkali resistance of basalt fiber accurately by establishing an ANN model. Our study provide a theoretical foundation for predicting the lifespan of basalt fibers under corrosive conditions while offering guidance for enhancing their alkali resistance.
