技术领域
本发明涉及功能性纺织制品技术领域,尤其涉及 TiO2/Ag+/N719/PU/CA多元荧光薄膜的制备方法。
背景技术
重金属汞是一种广泛存在于自然界中金属,主要以金属汞、汞盐和有机汞三种形式存在,而大多数汞盐都是剧毒物质,存在于水体中,可在环境中在动植物体内形成富集,误食容易使人体慢性神经中毒,严重者甚至死亡,危害严重。但日常生活中,人们不易发现的Hg2+存在,所以导致许多的汞误食现象,例如饮用水中的Hg2+,食物中所携带的Hg2+富集。
据世界卫生组织介绍:单质汞和甲基汞会毒害中央和周围神经系统。吸入汞蒸汽可对神经、消化和免疫系统,以及肺和肾造成损害,后果可能是致命的。汞的无机盐会腐蚀皮肤、眼睛和胃肠道,如果不小心食入,则可能引发肾中毒等症状。在被不同汞化合物的吸入、食入或表皮接触后,可能观察到神经和功能紊乱。症状包括震颤、失眠、记忆力减退、神经肌肉的影响、头痛和认知能力和运动功能障碍。接触空气中单质汞水平 20μg/m3或以上达几年之久的工人,可以观察到中枢神经系统中毒的轻微亚临床症状。对肾脏的影响已有报道,从尿蛋白增加到肾功能衰竭。
目前对Hg2+的检测主要有电化学分析法、中子活性分析法、质谱法和原子光谱法。而原子光谱法主要包括原子吸收光谱法、原子发射光谱法和原子荧光光谱法。

发明内容
本发明旨在公开一种通过检测荧光猝灭现象来判断金属离子浓度的TiO2/Ag+/N719/PU/CA多元荧光薄膜的制备方法。
本发明通过以下技术手段实现解决上述技术问题的:
一种TiO2/Ag+/N719/PU/CA多元荧光薄膜的制备方法,包括以下步骤:
(1)配置PU/CA混合纺丝溶液,包括以下步骤:

3)将制得的PU纺丝溶液和CA纺丝溶液按照体积比8:2混合,制得 PU/CA混合纺丝溶液;
(2)将TiO2加入至步骤(1)的PU/CA混合纺丝溶液中;
(3)将Ag+溶液加入至步骤(2)的溶液中;
(4)对步骤(3)的溶液进行静电纺丝,得到TiO2/Ag+/PU/CA薄膜;
(5)用N719钌染料溶液对步骤(4)中的薄膜进行浸泡整理,得到 N719改性TiO2/Ag+/PU/CA薄膜;
(6)干燥后,得产物。
优选地,所述步骤(4)中的PU/CA混合纺丝溶液在电压21kV、极距 18cm、流速2ml/h、直径为0.7mm针头的条件下制成TiO2/Ag+/PU/CA薄膜。
优选地,所述步骤(2)中浸泡整理包括以下步骤:
1)将N719钌染料溶解于无水乙醇中,在40℃温度下、搅拌12h,再避光处理一昼夜,制得5×10-4mol/L的染料溶液;
2)将TiO2/Ag+/PU/CA薄膜从锡纸上揭下来,浸泡到N719钌染料溶液中24h,取出阴干。
优选地,所述步骤(2)中,TiO2按照占据PU/CA混合纺丝溶液其溶质质量的8%混入。
优选地,所述步骤(4)中,Ag+溶液的溶剂为水,Ag+与TiO2的摩尔比2:100。
本发明还公开一种TiO2/Ag+/N719/PU/CA多元荧光薄膜,所述薄膜的荧光强度为1788a.u.、发射波长在608nm。
本发明还公开一种N719改性PU/CA薄膜,所述薄膜的红外光谱中,在1520cm-1处存在酰胺特征吸收峰,在770cm-1处存在N-与过度金属Ru 的配位峰,在2100cm-1处存在N配位的NC的振动峰。
发明还公开一种上述TiO2/Ag+/N719/PU/CA多元显色薄膜在对检测水体Hg2+含量的应用。
优选地,所述Hg2+含量≤1.5mmol/L。
本发明的优点在于:本发明通过对静电混纺含CA材料的PU/CA薄膜的接触角检测,我们发现含有CA材料的薄膜亲水性有了很大的提高,对后道工序的实现提供了前提,而对PU/CA薄膜的电镜扫描则表征了荧光物质载体材料的微观表面结构是由纤维堆砌而成的,且成型良好,细度均价,具有比表面积大的特点,达到利用大比表面积增强荧光性的要求。
本发明的Ag+具有增强N719染料荧光性能的作用,所有可作为荧光增强剂使含N719染料的PU/CA薄膜的荧光性能得以增强。然后将添加了Ag+的含N719染料的PU/CA薄膜作为荧光检测工具检测不同浓度的Hg2+,浓度梯度分别为0mmol/L、0.2mmol/L、0.4mmol/L、0.6mmol/L、0.8mmol/L 和1mmol/L的硝酸汞溶液,实验发现随着Hg2+浓度的增加,荧光逐渐猝灭,具有很好的检测效果,而检测的灵敏度应该在Hg2+浓度在1.5mmol/L以下。

实施例1
静电纺丝溶液制备
PU溶液:将四氢呋喃、N-N二甲基甲酰胺和氯仿体积按4.5:4.5:1的比例混合,加入占溶剂质量比为6%的PU切片,40℃烘箱烘燥2h制得PU 纺丝溶液;

实施例3
N719钌染料溶液配制与接枝
配制5×10-4mol/L的染料溶液:将N719钌染料溶解于无水乙醇中,在 40℃温度下用磁力搅拌器搅拌12h,再避光处理一昼夜,既可制得 5×10-4mol/L的染料溶液;
将制得的PU/CA薄膜从锡纸上揭下来,剪成面积为2cm2大小的片膜,浸泡到N719钌染料溶液中24h,取出阴干,得到实验用的N719改性PU/CA 薄膜。
实施例4
金属离子添加物
分别在实施例1中的PU/CA混合纺丝溶液中加入TiO2、Cu2+溶液、 Ag+溶液,分别制得含TiO2、TiO2/Cu2+、TiO2/Ag+、TiO2/Cu2+/Ag+的四种 PU/CA薄膜。其中TiO2按照占据PU/CA混合纺丝溶液其溶质质量的8%混入溶液;
Ag+、Cu2+溶液的溶剂为水,Ag+、Cu2+与TiO2的摩尔比均为2:100。
实施例5
荧光淬灭检测
用去离子水配置0.2mmol/L、0.4mmol/L、0.6mmol/L、0.8mmol/L和 1mmol/L的硝酸汞溶液,做荧光检测,取实施例4中的各个PU/CA薄膜,再用其检测Hg+溶液。
实施例6
N719钌染料与PU/CA薄膜的结合牢固
将纺丝溶液用纺丝机纺制的薄膜,用锡纸作为载体接收纤维,纤维堆积一段时间后就形成了薄膜,当厚度达到一定程度后可将薄膜从锡纸上揭下,得到实验用的N719钌染料载体,颜色洁白,手感丰厚。而在N719钌染料中浸泡24小时(避光处理)后的薄膜则被染成紫红色,表明N719钌染料已与薄膜结合在一起。
实施例7
扫描电镜分析
对PU薄膜、CA薄膜、PU/CA薄膜、N719改性PU/CA薄膜分别做扫描电镜,实验测试电压为3kV,放大倍率分别为1000倍、3000倍和5000 倍。如图1-3所示,PU的扫描电镜图中可以清晰看出,纯PU溶液纺制的微纳薄膜虽然有些零散分布的珠粒,但从总体上看成纤效果还是比较良好的,PU薄膜基本上是由一根根的纤维堆砌而成,纤维直径粗细比较均匀,是一张不错的纤维薄膜;如图4-6所示,CA的扫描电镜图可以看出,CA 薄膜纤维直径粗细及不均匀,而且有大量的成片状糊块带,从整体上看纤维直径粗细相差也甚大,成纤效果不是很理想,基于CA薄膜的表面结构较差和脆性较大的缺陷,实验虽然利用其增加薄膜吸水性,但必须考虑整体的结构性能,所以进行配比时的比例应该不能太高而避免影响薄膜的整体性能;如图7-9所示,而PU/CA混纺的薄膜,则较少出现珠粒,且纤维直径粗细均匀,直径均在10nm至100nm之间,大体在50nm左右,条理清晰,所以在此PU/CA(8/2)比例下的薄膜材料的整体成纤性能比单纺PU 材料的成纤性能不仅提高了,而且由于CA材料的加入还有了亲水性能还有很大的提高,符合本次的实验纳米纤维比表面积大和亲水性强的要求;如图10-12所示,在浸泡了N719染料后,PU/CA薄膜仍然结构完好,没有比浸泡之前发生结构变形,说明长时间的浸泡N719染料溶液不会对 PU/CA薄膜结构造成破坏,实验所用的薄膜能很好的体现比表面积大的优良特点。
实施例8
PU/CA薄膜亲水性分析
采用的实验检测方法多与溶液接触有关,所以要求薄膜必须具有较好的亲水性,PU是一种很好的静电纺丝材料,其所纺得的薄膜强度高弹性大,但由于PU是一种化学纤维,分子中缺少亲水性基团,造成了PU材料的亲水性较差,但是CA材料却是由天然植物纤维再生而成的再生纤维,分子中具有较多的亲水基团,是一种亲水较好的的材料,但在实际静电纺丝制造中却不易纺制,且强度低,脆性大,不具有使用性。所以本发明采用的以PU材料为主混入CA(PU/CA的质量比为8/2)的方式在保证薄膜的实用性的同时综合了两种材料的优点,适当提高其亲水性。
在对PU薄膜和PU/CA混纺薄膜的亲水接触角检测实验中发现,纯PU 薄膜的接触角较小,而混纺的PU/CA薄膜接触角明显增大。表明了混纺薄膜材料由于亲水性CA加入的原因,CA纤维是以纤维素糟粕为原料制成的,属于再生天然纤维,虽然纤维素中的羟基被醋酯乙酰化而生成纤维素脂,但仍然比化学纤维的亲水性好很多,所以能很好的提高薄膜的亲水性。
实施例9
红外光谱分析
如图13所示,对PU/CA薄膜和N719改性PU/CA薄膜分别做红外光谱表征。图中,位置在上的曲线为PU/CA薄膜的红外光谱、位置在下的曲线为N719改性PU/CA薄膜的红外光谱。
PU/CA薄膜和N719改性PU/CA薄膜曲线中,我们可以看到在3357 cm-1处有强烈的吸收峰,它是-OH的特征峰,明显N719改性PU/CA薄膜的峰强度要大。从N719改性PU/CA薄膜图中我们可以看观察到,在 1520cm-1出现较强吸收峰,我们知道它们是酰胺(NH—CO-NH)的特征吸收峰。在770cm-1以附近应有c=s的振动峰,是N-与过度金属Ru的配位峰。另外,可看出含N719染料的薄膜在2100cm-1处有一强烈的吸收峰,它是 N配位的NC的振动峰。以上说明N719染料成功附着到了PU/CA薄膜上。
实施例10
比色反应
将上述N719改性PU/CA薄膜阴干后检测不同浓度的Hg2+,用Hg2+浓度分别为0mmol/L、0.2mmol/L、0.4mmol/L、0.6mmol/L、0.8mmol/L和 1mmol/L的硝酸汞溶液浸润N719改性PU/CA薄膜。
薄膜颜色随Hg2+浓度的增加颜色逐渐由紫红色向橘黄色改变,具有较好的比色现象。这原因可能是Hg2+与N719染料中的显色基团产生配位的导致了电子轨道的的跳跃,从而导致吸收的波长发生变化,随着Hg2+浓度的增加这类基团的数量增加从而颜色逐渐变化。
但在用Ag+、Cu2+等浸润后,薄膜的颜色也会出现很大的变化,含N719 染料薄膜颜色紫红色、与Ag+反应后的颜色变成了橘黄色、与Cu2+反应后的颜色却变成了浅紫色和与Ag+/CU2+反应后的颜色变成了橘黄色。
将N719改性PU/CA薄膜用Ag+浸润后再与浓度分别为0mmol/L、 0.2mmol/L、0.4mmol/L、0.6mmol/L、0.8mmol/L和1mmol/L的硝酸汞溶液浸润后,颜色几乎都为橘黄色,并没有显著的差异,不再能形成良好的比色现象。
造成这种现象的可能原因是Ag+的大量加入造成了N719染料中的显色基团被Ag+先配位占据,导致Hg2+后来加入后无法再形成其与N719染料的配位基团而显示Hg2+与显色基团配位而显示的颜色。
实施例11
荧光分析
将N719改性后含TiO2、TiO2/Ag+、TiO2/Cu2+和TiO2/Ag+/Cu2+的四个不同的PU/CA薄膜样品。分别做荧光光度计分析,在激发波长458nm的时候,荧光发射峰最高。
在图14荧光强度图中,按照曲线的峰值高度由上至下依次为TiO2/Ag+/ N719/PU/CA薄膜、TiO2/Ag+/Cu2+/N719/PU/CA薄膜、TiO2/N719/PU/CA 薄膜、TiO2/Cu2+N719/PU/CA薄膜的荧光强度曲线。
激发波长460nm时荧光强度最大,发射波长相对应的为608nm。浸润TiO2/Ag+的PU/CA薄膜峰发射峰最高,说明其荧光效果最好,其次依次是 TiO2/Ag+/Cu2+的PU/CA薄膜,TiO2的PU/CA薄膜和TiO2/Cu2+的薄膜。这表明在含N719染料的PU/CA薄膜中加入Ag+对其荧光性能有增强的效果,而Cu2+的加入则一定程度上减弱了N719染料的荧光性能。其原因可能是因为金属离子与荧光基团之间的距离差异导致了荧光基团的跃进方式,金属Cu2+与荧光基团的距离应该大于30nm,导致了荧光的增强效果的急剧减弱,而Ag+与荧光基团的距离在2nm于30nm之间,荧光增强。所以实验表明Ag+的添加具有增强N719染料荧光性能的作用。
如图15所示,图中曲线按照其峰值高度由上至下依次为Hg2+浓度为 0mmol/L、0.2mmol/L、0.4mmol/L、0.6mmol/L、0.8mmol/L和1mmol/L的硝酸汞溶液浸润TiO2/Ag+/N719/PU/CA薄膜后,然后进行荧光性检测的强光强度曲线。
选用含TiO2/Ag+/N719/PU/CA薄膜进行Hg2+荧光性能检测,用浓度分别为0mmol/L、0.2mmol/L、0.4mmol/L、0.6mmol/L、0.8mmol/L和1mmol/L 的硝酸汞溶液浸润TiO2/Ag+/N719/PU/CA薄膜,然后进行荧光性检测,荧光强度随着Hg2+的浓度增加而逐渐减小,出现荧光猝灭的反应。伴随着Hg2+浓度的增加,Hg2+逐渐荧光基团发生配位反应,随着荧光基团的被取代而使得荧光发生猝灭;或者是由于Hg2+与荧光基团的距离小于2nm导致了荧光的猝灭。检测的灵敏度应该在Hg2+浓度在1.5mmol/L以下,以此规律可作为Hg2+的荧光检测。
