Smart textiles based on monitoring systems of health conditions, structural behaviour, and external environmental conditions have been presented as elegant solutions for the increasing demands of health care. In this study, cotton fabrics (CFs) were modified by a common strategy with a dipping-padding procedure using reduced graphene oxide (RGO) and a photosensitive dye, spiropyran (SP), which can detect environmental UV light. The morphology of the CF is observed by scanning electron microscopy (SEM) measurements showing that the topography structure of coatings is related to the SP content. The resistance of the textile sensors decreases after UV radiation, which may be attributed to the easier electron transmission on the coatings of the CF. With the increase of SP content, the introduction of a large amount of SP within the composites could cause discontinuous distributions of RGO in the fiber surfaces, preventing electron transmission within the coatings of the RGO. The surface wettability of the coatings and the sweat sensitivity are also studied before and after UV radiation.
基于健康状况、结构行为和外部环境条件监测系统的智能纺织品，已被视为应对日益增长的医疗保健需求的优雅解决方案。在本研究中，采用一种常见策略，通过浸轧工艺使用还原氧化石墨烯（RGO）和一种能检测环境紫外光的光敏染料螺吡喃（SP）对棉织物（CFs）进行改性。通过扫描电子显微镜（SEM）测量观察CF的形态，结果表明涂层的形貌结构与SP含量有关。紫外辐射后纺织传感器的电阻降低，这可能归因于CF涂层上电子传输更容易。随着SP含量的增加，复合材料中大量SP的引入会导致RGO在纤维表面分布不连续，从而阻止RGO涂层内的电子传输。还研究了紫外辐射前后涂层的表面润湿性和汗液敏感性。
