Description

检测Fe3+的复合荧光聚酯膜及其制备方法
技术领域
本发明属于荧光检测领域,具体涉及一种检测Fe3+的复合荧光聚酯膜及其制备方法。
背景技术
荧光聚对苯二甲酸乙二酯复合膜材料通常采用普通荧光颜料与聚氯乙烯树脂混合后制成,在户外的、耐光性、耐晒性、耐酸碱性能差,只能用于户外短期或户内使用。近年来发现将合适的纳米尺寸材料加入聚合物基质中已经成为一种扩大聚酯膜应用领域有效的方法,聚酯膜作为一种高分子塑料薄膜具有良好的抗皱性、保形性、耐热性、透光性、化学稳定性、强度等优良性能,使其能够作为良好的碳点载体。通过将碳点涂布在聚酯膜表面形成纳米复合材料,可丰富聚酯膜的各种性能,例如机械性能,热稳定性,阻燃性等。并且,所得的复合荧光聚酯膜具有原始碳点的功能,可用于检测溶液中的Fe3+。
发明内容
本发明的目的在于提供一种腹膜透析用杀菌消毒帽。
本发明为实现上述目的,采用以下技术方案:
一种检测Fe3+的复合荧光聚酯膜的制备方法,包括下述步骤:
1)丙烯酸和蛋氨酸通过水热法得到能够检测Fe3+的蓝色荧光碳点溶液;
2)将聚酯膜固定在卷染机的滚筒上,卷染池内为步骤1)制备的荧光碳点溶液,染料池内的温度为70-110℃,染色时间为20-60min,聚酯膜染色后烘干,然后经过漂洗,漂洗水温为20-40℃,最后烘干形成具有碳点涂布的功能化聚酯膜。
所述的聚酯膜为聚对苯二甲酸乙二醇酯膜。
步骤1)的具体步骤为:将丙烯酸和蛋氨酸溶解在水中,形成混合液;然后将混合液转移到水热高压反应釜中,之后放入马弗炉中200℃下加热12h;反应完成后,待反应釜冷却至室温后旋蒸除去水分,之后在乙醇溶液中透析得到荧光碳点溶液;
所述的丙烯酸和蛋氨酸的摩尔比为1:0.75。
透析袋的规格为MW=3500Da。
本发明还包括一种检测Fe3+的复合荧光聚酯膜,采用所述的制备方法得到。
与现有技术相比,本发明的有益效果是:
本发明通过碳点与聚酯膜的结合而得到一种能够检测Fe3+的功能化聚酯膜,进而实现对Fe3+的小型化,轻量化的便捷检测。其原理为由于碳点涂布于聚酯膜表面,在紫外灯下能观察到聚酯膜发出蓝色荧光。将功能化的聚酯膜浸入到有Fe3+的溶液体系中,再拿到紫外灯下观察则蓝色荧光消失。
