Abstract

本发明公开了一种基于三氧化钼上转换纳米材料的荧光纤维，利用MoO3:Yb,Er/Tm之间的静电作用作为成膜推动力，将纱线或织物依次浸渍在带正电的MoO3:Yb,Er/Tm水溶液和带负电的MoO3:Yb,Er/Tm水溶液中，根据需要决定纱线或织物表面MoO3:Yb,Er/Tm组装的层数，从而赋予纱线或织物上转换荧光性能。

Description

基于三氧化钼上转换纳米材料的荧光纤维
技术领域
本发明涉及基于三氧化钼上转换纳米材料的荧光纤维，属纤维材料领域。
背景技术
近几年来，纳米颗粒受到大量的关注，由于其粒径小，比表面积大，表现出尺寸效应、表面效应，具有光、电、磁等特殊的性能，被广泛应用于医药、光电器件、生物传感器等领域。而将纤维材料与荧光纳米颗粒相结合的潜在应用已经引起人们的关注。然而采用荧光纳米颗粒结合的方法制备荧光纤维存在局限性，纤维表面粘结的荧光纳米颗粒稳定性不好，耐洗性较差。
稀土上转换纳米发光材料（UCNPs）能够通过双光子或多光子机制把低能量长波辐射转换成高能量短波辐射，其具备毒性低、化学稳定性高、光稳定性强、信噪比高、发射谱带窄、荧光寿命长、反斯托克斯位移大、较大的光穿透深度、无光漂白、无背景荧光以及对生物组织无损伤等诸多优点，在免疫分析、生物标记、生物传感、生物成像、药物载体、光动力治疗、光热治疗、光导开关、信息存储、食品安全检测、光催化以及太阳能电池等领域有着广泛的研究和应用。
中国发明专利201410701957.9一种荧光沙柳再生纤维素纤维及其制备方法，中国发明专利201410702142.2一种荧光Lyocell纤维及其制备方法，中国发明专利201410702118.9一种静电纺荧光PVA纳米纤维膜及其制备方法将UCNPs添加到纺丝液中，通过高效共混、湿法纺丝技术制备得到具有优异荧光性能的纤维。目前还未见将UCNPs直接组装到纤维上的文献报道。
发明内容
本发明针对上述不足，提供基于三氧化钼上转换纳米材料的荧光纤维。
本发明通过下述技术方案予以实现：将端氨基超支化聚合物修饰MoO3:Yb,Er/Tm和端羟基超支化聚合物修饰MoO3:Yb,Er/Tm分别配制成0.1-5g/L的水溶液，随后将纱线或织物浸渍在80℃的端氨基超支化聚合物修饰MoO3:Yb,Er/Tm水溶液中10-60min，浴比1:10，取出后用去离子水反复冲洗，烘干；然后将上述纱线或织物浸渍在80℃的端羟基超支化聚合物修饰MoO3:Yb,Er/Tm水溶液中10-60min，浴比1:10，取出后用去离子水反复冲洗，烘干，至此已将一层MoO3:Yb,Er/Tm组装到纱线或织物的表面，随后依次在端氨基超支化聚合物修饰MoO3:Yb,Er/Tm和端羟基超支化聚合物修饰MoO3:Yb,Er/Tm整理液中重复上述操作，根据需要决定纱线或织物表面MoO3:Yb,Er/Tm组装的层数。
端氨基超支化聚合物的合成可参考下述公开文献：端氨基超支化聚合物及其季铵盐的制备与性能[J].高分子材料科学与工程, 2009, 25(8): 141-144；CN200710020794.8一种超支化活性染料无盐染色助剂；Coloration Technology, 2007, 123(6): 351-357；AATCC Review, 2010, 10(6): 56-60；Biomacromolecules, 2010, 11(1): 245-251；Chemical Research in Chinese Universities, 2005, 21(3): 345-354。
端羟基超支化聚合物的合成可参考下述公开文献：杨保平,张鹏飞,崔锦峰等.端羟基超支化聚合物的改性研究及其在涂料中的应用[J].中国涂料,2011,26(3):53-57；王学川,胡艳鑫,郑书杰等.端羟基超支化聚合物对Fe3+吸附行为研究[J].化工新型材料,2011,39(9):26-29,47；强涛涛,张国国,王学川等.端羟基超支化聚合物的合成与改性[J].日用化学工业,2012,42(6):413-417。
端氨基超支化聚合物修饰MoO3:Yb,Er/Tm和端羟基超支化聚合物修饰MoO3:Yb,Er/Tm制备步骤可参考文献：中国发明专利CN201410702157.9一种水溶性三氧化钼上转换纳米材料及其制备方法。
与现有技术相比，本发明的优点在于：利用带负电的端羟基超支化聚合物修饰MoO3:Yb,Er/Tm与带正电的端氨基超支化聚合物修饰MoO3:Yb,Er/Tm之间的静电作用作为成膜推动力。MoO3:Yb,Er/Tm通过正负离子键的结合作用附着在纱线或织物表面，避免了使用有害的化学交联剂，降低了对纱线或织物强力的影响。改性后的纱线或织物具有优异的上转换荧光性能和良好的耐洗、服用性能。
