技术领域
本发明涉及一种担载金属氧化物、导电高分子和二维纳米材料的柔性传感织物、制备方法及其应用。该柔性传感织物通过先将富含氧缺陷和结晶水的金属氧化物浸渍到织物表面，然后再复合导电高分子和二维纳米材料而成。本发明包含柔性传感织物、制备方法及其应用，属于传感技术领域。
背景技术
近来，柔性可穿戴传感器及其技术在未来的智慧医疗、工业产业、社会安全、航空航天领域发挥日益增强的作用。柔性衬底是实现可穿戴电子器件的一个关键因素。目前，先存柔性衬底如聚对苯二甲酸乙二酯(PET)，聚酰亚胺(PI)和聚偏二氟乙烯(PVDF)不仅会降低人们的舒适感，还会带来皮肤和柔性衬底的兼容性问题。尤其衬底表面担载的材料会受力弯曲后脱落，进而降低由其制造电子器件的稳定性。理想情况下，将可穿戴电子器件直接集成在衣服/工装表面，但二者之间的兼容性依然是发展高性能电子器件亟待解决的难题。为此，本专利拟采用金属氧化物、导电高分子和二维纳米材料合成复合材料，然后担载到柔性织物表面，进而可以集成在衣服/工装表面。本发明为新型的柔性传感织物，制备方法，在未来的可穿戴传感科技中有潜在的应用前景。
