Abstract

Multifunctional smart apparel with comfortable, hydrophobic, flexible, and washable nature is needed for next-generation fabrics in the military sector. Hence, we synthesized reduced graphene oxide (RGO) by cost- effective route and embedded on cotton cloth with polyvinyl alcohol as binder. X-ray diffraction pattern (XRD) and Raman spectra confirmed formation of RGO. RGO exhibited a broad response covering UV, Visible, and near-infrared regions of the solar spectrum. The photocatalytic efficiency of 50 mg RGO for 10 ppm methylene blue is 73 % at visible light in 2 h 15 min. Different ratios of polyvinyl alcohol (PVA) and RGO (1:1, 1:2. 1:4 and 1:6) were taken and coated on cotton cloth. The higher concentration of RGO(3RPC) on cloth exhibited a bandgap of 1.67 eV and contact angle of 134.45°. Lower water absorption ability (28 %) and water solubility ability (7.9 %) of 3RPC indicate it is concurrent with contact angle. 3RPC is lightweight, flexible, and hydrophobic and it exhibits broad absorption with low bandgap. Due to the water repellence nature and broad absorption, 3RPC can used as self-cleaning apparel for military society.

基于还原氧化石墨烯的多功能智能织物，适用于下一代军用时装

军事领域需要具有舒适、疏水、柔韧和可清洗特性的多功能智能服装，以满足下一代织物的需求。因此，我们采用经济有效的方法合成了还原氧化石墨烯（RGO），并以聚乙烯醇为粘合剂将其嵌入棉布上。X 射线衍射图（XRD）和拉曼光谱证实了 RGO 的形成。RGO 对太阳光谱中的紫外线、可见光和近红外区域具有广泛的响应。在可见光下，50 毫克 RGO 在 2 小时 15 分钟内对 10ppm 亚甲基蓝的光催化效率为 73%。取不同比例的聚乙烯醇（PVA）和 RGO（1:1、1:2、1:4 和 1:6）涂布在棉布上。浓度较高的 RGO（3RPC）在棉布上的带隙为 1.67 eV，接触角为 134.45°。3RPC 较低的吸水能力（28%）和水溶性（7.9%）表明它与接触角同时存在。3RPC 具有轻质、柔韧和疏水性的特点，并且具有低带隙的宽吸水性。由于 3RPC 具有防水性和广泛的吸水性，因此可用作军事社会的自洁服装。

期刊介绍： DRM is a leading international journal that publishes new fundamental and applied research on all forms of diamond, the integration of diamond with other advanced materials and development of technologies exploiting diamond. The synthesis, characterization and processing of single crystal diamond, polycrystalline films, nanodiamond powders and heterostructures with other advanced materials are encouraged topics for technical and review articles. In addition to diamond, the journal publishes manuscripts on the synthesis, characterization and application of other related materials including diamond-like carbons, carbon nanotubes, graphene, and boron and carbon nitrides. Articles are sought on the chemical functionalization of diamond and related materials as well as their use in electrochemistry, energy storage and conversion, chemical and biological sensing, imaging, thermal management, photonic and quantum applications, electron emission and electronic devices. The International Conference on Diamond and Carbon Materials has evolved into the largest and most well attended forum in the field of diamond, providing a forum to showcase the latest results in the science and technology of diamond and other carbon materials such as carbon nanotubes, graphene, and diamond-like carbon. Run annually in association with Diamond and Related Materials the conference provides junior and established researchers the opportunity to exchange the latest results ranging from fundamental physical and chemical concepts to applied research focusing on the next generation carbon-based devices.
