Of late, there is a substantial demand for the development of multifunctional materials and hence they have allured enormous interest in every other application possible. With the threat of escalating electromagnetic (EM) pollution, there is a strong need to develop materials and strategies to curb it. Textiles have been used as promising candidates for electromagnetic waves, particularly in the microwave frequency ranges, due to their various advantages in terms of flexibility, lightweight and conformability in comparison to the existing materials. Further to this, there is an inherent advantage of creating multiple interfaces for microwave attenuation on coating textiles with functional coatings. Herein, we report for the first time, the preparation of a multifunctional coating that is based on iron titanate (FT) and multiwalled carbon nanotubes (CNT) which can shield both microwaves and UV radiations. The iron titanate used here is sourced from a sustainable precursor – the ilmenite sand, while the CNT is commercially sourced. In order to demonstrate the contribution of FT in EMI shielding, another particle was also used – this was synthesized in the same protocol as that of FT with copper ions incorporated (CuFT). On comparison, it was found that FT tends to interact with and attenuate EM radiation along with CNT – much better than CuFT. The coated fabrics show an EMI shielding effectiveness of −30 dB for a stack of four layers in the broadbands viz. X and Ku – translating to a 99.9% attenuation of the incident EM signals. Further, there is a jump in conductivity of around four orders in magnitude for the coated fabric in comparison to the neat fabric. It is worth to note that the coating confers an ability to block 99.9% of the UV radiation over the wavelength ranging 200–400 nm. Furthermore, the prepared coatings significantly improve the flame retarding properties of the neat fabric. With such remarkable properties, these coatings have the huge potential to significantly enhance the commercial value of cotton fabrics without adding much to its cost.

最近，对开发多功能材料的需求很大，因此它们在所有其他可能的应用中都引起了极大的兴趣。随着电磁 (EM) 污染升级的威胁，迫切需要开发材料和策略来遏制它。纺织品已被用作电磁波的有希望的候选者，特别是在微波频率范围内，因为与现有材料相比，它们在柔韧性、重量轻和适应性方面具有各种优势。此外，在具有功能性涂层的纺织品涂层上创建多个用于微波衰减的界面具有固有的优势。在此，我们首次报道，制备基于钛酸铁 (FT) 和多壁碳纳米管 (CNT) 的多功能涂层，可屏蔽微波和紫外线辐射。这里使用的钛酸铁来自可持续的前体——钛铁矿砂，而 CNT 则来自商业来源。为了证明 FT 在 EMI 屏蔽中的贡献，还使用了另一种粒子——这是在与 FT 相同的协议中合成的，其中掺入了铜离子 (CuFT)。相比之下，我们发现 FT 往往与 CNT 一起与 EM 辐射相互作用并减弱它们——比 CuFT 好得多。对于宽带中的四层堆叠，涂层织物显示出 -30 dB 的 EMI 屏蔽效果，即。X 和 Ku – 转化为入射 EM 信号的 99.9% 衰减。更多，与纯织物相比，涂层织物的电导率跃升了大约四个数量级。值得注意的是，该涂层能够阻挡 200-400 nm 波长范围内 99.9% 的紫外线辐射。此外，所制备的涂层显着提高了纯织物的阻燃性能。凭借如此卓越的性能，这些涂层具有巨大的潜力，可以在不增加太多成本的情况下显着提高棉织物的商业价值。
