现代战场环境复杂多变
人员与装备面临高寒、电磁辐射、子弹冲击等威胁
亟需研发轻质便携的多功能防护材料。目前虽有织物多功能研究

采用MXene材料作为功能层
芳纶织物(Twaron)作为基础材料
有机硅胶作为表面防水层
制作多功能一体化材料MS-Twaron

In modern complex and dyn
amic battlefield environments
personnel and equipment are exposed to the threats such as extreme cold
electromagnetic radiation
and bullet impacts.Therefore
there is an urgent need to develop the lightweight and portable multifunctional protective materials.While the existing research explores multifunctional textiles
the physical integration of single-function materials exacerbates mass and cost issues.MS-Twaron multifunctional protective material is made by using MXene materials as the functional layer and aramid fibers (Twaron) as the base material with silicone gel as a surface waterproof layer.The contact angle test
electromagnetic interference (EMI) shielding test
flame retardant test
ballistic test
and photo-thermal experiment are made on MS-Twaron.The results indicate that:1)Compared to the hydrophilic material Twaron (water contact angle of 29.7°)
MS-Twaron exhibits the excellent hydrophobic properties (water contact angle of 112.3°); 2)Compared to Twaron which exhibits no EMI properties
MS-Twaron with MXene mass fraction of 8.61% shows an improved EMI properties in X-band
ranging from 13.490dB to 14.969dB; 3)Compared to Twaron
MS-Twaron exhibits a 5.0s increase in afterglow time
a 3.5s reduction in glowing time
and a 5.3mm decrease in average char length.MS-Twaron has impact resistant properties of which the ballistic indentation depth is 6.12mm smaller than that of Twaron.The surface temperature of MS-Twaron can achieve up to 50.22℃ under natural light (light intensity of 100.3×10

DOI: 10.12382/bgxb.2022.0578 http://doi.org/10.12382/bgxb.2022.0578 芳纶凭借其轻质高强的特点广泛应用于防弹领域。为提高单层芳纶织物的抗钝伤能力,采用热塑性树脂聚乙烯(Polythene,PE)与石墨烯纳米粒子表面改性方法提升芳纶织物的抗钝伤性能。以背衬凹陷为标准,对不同质量配比改性芳纶织物的抗钝伤能力和能量吸收特性进行测试对比。对比结果表明:石墨烯和PE两种改性方法均可提升芳纶织物的抗钝伤能力,其中PE改性方法使得改性织物面密度增加较小但抗钝伤能力显著提升,10%PE的防弹能力和比吸能值较纯芳纶分别提升了18.0%和30.8%;石墨烯改性织物刚性的增加使其低速抗钝伤能力增强,但是过大的纱线间摩擦使其高速防护能力减弱,2%石墨烯粉体为石墨烯改性织物的最佳配比。此外,优化验证得到了2层10%PE和13层的6层正交超高分子量PE无纬布防弹衣组合设计。

(in Chinese) DOI: 10.12382/bgxb.2022.0578 http://doi.org/10.12382/bgxb.2022.0578 Aramid is widely used in the field of ballistic protection due to its light weight and high strength. In order to improve the trauma resistance of single-layer aramid fabrics, the surface modification methods of thermoplastic resin polyethylene (PE) and graphene nanoparticles (GR) are used innovatively to improve the ballistic performance of aramid fabrics. The trauma resistance and energy absorption of modified aramid fabrics with different mass ratios are studied based on the backface significance (BFS). The results show that both graphene and polyethylene modification methods can improve the blunt trauma resistance. The surface density of the modified fabric is increased slightly by polyethylene modification, but the resistance to blunt injury is significantly improved. Compared with pure aramid fabric, the bullet-proof ability and specific energy absorption value of 10% PE are increased by 18.0% and 30.8%, respectively. The increased rigidity of graphene-modified fabric increases its resistance to blunt injury at low speed, but the excessive inter-yarn friction weakens its resistance to blunt injury at high speed. 2% GR is the best ratio for graphene-modified fabric. In addition, the combined design of body armor with 2 layers of 10% PE and 13 layers of six layers of orthogonal UHMWPE unidrectional fabric is obtained through optimization and verification.

DOI: 10.1007/s40820-023-01203-5 http://doi.org/10.1007/s40820-023-01203-5 There is an urgent demand for flexible, lightweight, mechanically robust, excellent electromagnetic interference (EMI) shielding materials. Two-dimensional (2D) transition metal carbides/nitrides (MXenes) have been potential candidates for the construction of excellent EMI shielding materials due to their great electrical electroconductibility, favorable mechanical nature such as flexibility, large aspect ratios, and simple processability in aqueous media. The applicability of MXenes for EMI shielding has been intensively explored; thus, reviewing the relevant research is beneficial for advancing the design of high-performance MXene-based EMI shields. Herein, recent progress in MXene-based macrostructure development is reviewed, including the associated EMI shielding mechanisms. In particular, various structural design strategies for MXene-based EMI shielding materials are highlighted and explored. In the end, the difficulties and views for the future growth of MXene-based EMI shields are proposed. This review aims to drive the growth of high-performance MXene-based EMI shielding macrostructures on basis of rational structural design and the future high-efficiency utilization of MXene.© 2023.

DOI: 10.1126/science.aag2421 http://doi.org/10.1126/science.aag2421 Materials with good flexibility and high conductivity that can provide electromagnetic interference (EMI) shielding with minimal thickness are highly desirable, especially if they can be easily processed into films. Two-dimensional metal carbides and nitrides, known as MXenes, combine metallic conductivity and hydrophilic surfaces. Here, we demonstrate the potential of several MXenes and their polymer composites for EMI shielding. A 45-micrometer-thick Ti3C2Tx film exhibited EMI shielding effectiveness of 92 decibels (>50 decibels for a 2.5-micrometer film), which is the highest among synthetic materials of comparable thickness produced to date. This performance originates from the excellent electrical conductivity of Ti3C2Tx films (4600 Siemens per centimeter) and multiple internal reflections from Ti3C2Tx flakes in free-standing films. The mechanical flexibility and easy coating capability offered by MXenes and their composites enable them to shield surfaces of any shape while providing high EMI shielding efficiency.Copyright © 2016, American Association for the Advancement of Science.

DOI: 10.1021/acs.nanolett.6b04339 http://doi.org/10.1021/acs.nanolett.6b04339 Ceramic biomaterials have been investigated for several decades, but their potential biomedical applications in cancer therapy have been paid much less attentions, mainly due to their lack of related material functionality for combating the cancer. In this work, we report, for the first time, that MAX ceramic biomaterials exhibit the unique functionality for the photothermal ablation of cancer upon being exfoliated into ultrathin nanosheets within atomic thickness (MXene). As a paradigm, biocompatible TiC nanosheets (MXenes) were successfully synthesized based on a two-step exfoliation strategy of MAX phase TiAlC by the combined HF etching and TPAOH intercalation. Especially, the high photothermal-conversion efficiency and in vitro/in vivo photothermal ablation of tumor of TiC nanosheets (MXenes) were revealed and demonstrated, not only in the intravenous administration of soybean phospholipid modified TiC nanosheets but also in the localized intratumoral implantation of a phase-changeable PLGA/TiC organic-inorganic hybrid. This work promises the great potential of TiC nanosheets (MXenes) as a novel ceramic photothermal agent used for cancer therapy and may arouse much interest in exploring MXene-based ceramic biomaterials to benefit the biomedical applications.
