Development of Thermal Camouflage Polyester-Cotton Blended Fabric for Defense Security Personnel via Coating with Graphene Oxide and Reduced Graphene Oxide

ABSTRACT

In this study, graphene oxide (GO) was prepared with modified Hummer’s method while reduce graphene oxide (rGO) was prepared in the presence of hydrazine hydrate and then coated on polyester cotton (PC) blend camouflage pattern print fabric using the pad-dry-cure method. The as-synthesized GO and rGO were characterized by dynamic light scattering (DLS) analysis, X-ray diffraction (xRD), and UV-visible spectrophotometry. The surface morphology and the thermal camouflage property of the coated fabric were investigated by scanning electron microscopy (SEM) and infrared thermal imaging test, respectively. The average particle size of GO and rGO were 99.8 nm and 0.4 nm, respectively. The fabrics treated with GO and rGO apparently reduced the emitting temperature of the human body and made it similar to the surrounding environment. The increase in the concentration of coating materials (GO and rGO) resulted in the enhancement of camouflage property. Interestingly, the camouflage property of the coated fabric was very good even after several washing cycles. Based on these scientific outcomes, the coating of PC fabric with GO and rGO is a novel and successful approach in the development of thermal camouflage technical textiles which can be potentially applied on pilot-scale experiments to establish its industrial-scale feasibility.

摘要

在本研究中，使用改进的Hummer法制备氧化石墨烯（GO），同时在水合肼存在下制备还原氧化石墨烯，然后使用垫干固化法将其涂覆在涤棉（PC）混合迷彩图案印花织物上. 通过动态光散射（DLS）分析、X射线衍射（XRD）和紫外-可见分光光度法对合成的GO和rGO进行了表征. 通过扫描电子显微镜（SEM）和红外热成像测试分别研究了涂层织物的表面形貌和热伪装性能. GO和rGO的平均粒径分别为99.8 nm和0.4 nm. 用GO和rGO处理的织物明显降低了人体的发射温度，使其与周围环境相似. 涂层材料（GO和rGO）浓度的增加导致伪装性能的增强. 有趣的是，即使经过几次洗涤循环，涂层织物的伪装性能也非常好. 基于这些科学成果，在PC织物上涂覆GO和rGO是开发热伪装技术织物的一种新的、成功的方法，可以潜在地应用于中试实验，以确定其工业规模的可行性.
