Ultraviolet (UV)-protective cotton fabrics are necessary for outdoor cotton clothing. In this study, boron and nitrogen co-doped carbon dots (BN-CD) are synthesized by one-pot hydrothermal carbonization, and consequently served as UV-absorber for cotton textiles. Fourier transform infrared, transmission electron microscope, scanning electron microscope and UV–Vis spectroscopy are used to characterize the structure and properties of BN-CDs and cotton fabrics finished by BN-CDs. The UV protection property and laundering durability of treated cotton fabrics are also measured. The results show that as-prepared BN-CD has high fluorescence and down-conversion fluorescence emission. The cotton fabric finished by the BN-CD and poly(vinyl alcohol) exhibits a UV transmittance of less than 4% in the range of 280–400 nm, a UV protection factor value of up to 38.6 and good laundering durability, indicating a promising potential of BN-CD as UV absorbers for finishing cotton fabrics.

含硼和氮共掺杂碳点的棉织物的紫外线防护

防紫外线(UV)棉织物是户外棉服装所必需的。在这项研究中,硼和氮共掺杂碳点(BN-CD)是通过一锅水热碳化法合成的,因此可作为棉纺织品的紫外线吸收剂。傅立叶变换红外,透射电子显微镜,扫描电子显微镜和UV-Vis光谱用于表征BN-CD和由BN-CD整理的棉织物的结构和性能。还测量了处理过的棉织物的紫外线防护性能和洗涤耐久性。结果表明,所制备的BN-CD具有高荧光和下转换荧光发射。由BN-CD和聚乙烯醇整理的棉织物在280-400 nm范围内的紫外线透射率小于4%,
