Description

一种银纳米粒子薄膜及制备方法
技术领域
本发明涉及薄膜的制备，尤其是一种可以大规模一次性成型的银纳米粒子薄膜；将该薄膜用于海产品的包装，能够监测海产品新鲜程度。
背景技术
随着物质条件的不断丰富，日常生活饮食中对海产品的需求愈加明显。但海产品却存在着诸多隐患问题，只有在保证新鲜度的情况下才对人体是有益处的，而如果是变质的海产品则会对身体带来坏的影响，严重时危及生命。而现有的海产品监测方法虽然较多，但大多数还只是停留在用专业的仪器设备进行检测，难以做到商业化、便携化的应用。
近年来，一些研究通过去分辨海产品新鲜时和不新鲜时的一些不同特征作为对照，从而可以监测海产品的新鲜程度，如专利号200910308398.4的海产品气味辨别方法，虽然对于海产品的新鲜程度可以做到一定程度上的监测，但存在的问题是，上述方法所采用的分析技术、监测方法复杂，尚不能做到商业应用中便携化的应用。
发明内容
本发明的目的是针对现有技术的不足而提供的一种银纳米粒子薄膜及制备方法，该薄膜可实现在现有的海产品包装上进行新鲜程度的监测，具有简单、成本低、效率高的优点。
实现本发明目的的具体技术方案是：
一种银纳米粒子薄膜，特点是：该膜以衬底为主体，在衬底上生长银层后，利用还原剂析出银纳米粒子，并形成银层；将该薄膜析出银层的面作为海产品的内包装层，能够监测海产品的新鲜程度；其中，所述衬底为聚对苯二甲酸乙二醇酯（PET）。
一种上述银纳米粒子薄膜的制备方法，该方法包括以下具体步骤：
步骤1：选一衬底贴附于玻璃片上，将贴附有衬底的玻璃片浸泡在纯度为95%的乙醇溶液中超声震荡25～30分钟；
步骤2：将步骤1所得衬底用去离子水冲洗干净，浸泡在纯度为99%的正丁胺中，50℃下50～60分钟，之后用去离子水冲洗，放至室温；
步骤3：将步骤2所得衬底使用银氨法生长银层，具体包括：
S3.1：将硝酸银溶于去离子水中，搅拌均匀，得浓度为0.02～0.03mol/L的硝酸银溶液；
S3.2：将S3.1所得的硝酸银溶液缓慢滴加NH3含量为25%～28%的氨水，使得溶液从浑浊变澄清，滴定结束，得到银氨溶液；
S3.3：将步骤2所得衬底浸入S3.2所得的银氨溶液中13～15分钟；
S3.4：将S3.3所得衬底去离子水冲洗，并置于浓度为8～10mmol／L的还原剂中使之析出银纳米粒子，并形成银层；
S3.5：将S3.4所得衬底去离子水冲洗，室温干燥20～25分钟；
步骤4：将步骤3所得衬底从玻璃片上撕下，得到所述银纳米粒子薄膜。
所述衬底为聚对苯二甲酸乙二醇酯（PET）。
所述还原剂为硼氢化钠溶液或过氧化氢溶液。
本发明的薄膜，用于海产品的监测相比传统监测方法而言，不需特定的实验温度及专业设备，且可以与现有的海产品包装实现衔接，可以大规模制造、性价比高。
附图说明
图1为本发明制备方法流程图；
图2为本发明制备方法步骤3的流程图。
具体实施方式
下面结合附图，对本发明进行详细描述。
参阅图1-2，本发明银纳米粒子薄膜的制备包括以下具体步骤：
S1：选一衬底12贴附于玻璃片11上，将该衬底浸泡在纯度为95%的乙醇溶液13中超声震荡25～30分钟；
S2：将步骤1所得衬底12用去离子水冲洗干净，浸泡在纯度为99%的正丁胺14中，50℃下50～60分钟，之后用去离子水冲洗，放至室温；
S3：将步骤2所得衬底12使用银氨法生长银层，具体包括：
S3.1：将硝酸银溶于去离子水中，搅拌均匀，得浓度为0.02～0.03mol/L的硝酸银溶液21；
S3.2：将S3.1所得的硝酸银溶液缓慢滴加NH3含量为25%～28%的氨水22，使得溶液从浑浊变澄清，滴定结束，得到银氨溶液23；
S3.3：将步骤S2所得衬底12浸入S3.2所得的银氨溶液25中13～15分钟；
S3.4：将S3.3所得衬底12去离子水冲洗，并置于浓度为8～10mmol／L的还原剂24中使之析出银纳米粒子，并形成银层25；
S3.5：将S3.4所得衬底12去离子水冲洗，室温干燥20～25分钟；
S4：将S3所得衬底12从玻璃片11上撕下，得到所述银纳米粒子薄膜；将该薄膜析出银层的一面作为海产品的内包装层，能够监测海产品的新鲜程度。
本发明是这样制作使用的：
首先，将衬底PET浸泡在乙醇溶液中超声处理，是为了去除表面杂质，以确保衬底PET表面干净。之后将其浸泡在正丁胺中，使得PET表面活性化。然后配置银氨溶液，将PET衬底浸入银氨溶液中13～15min，使之发生络合反应，利用0.16～0.2mmol／L的过氧化氢溶液作为还原剂使得表面析出形成银层，过氧化氢溶液浓度不宜过高，否则所生长出来的银层较疏松。所形成的银层在显微镜下观察银颗粒为50～100nm，即生长所得为银纳米粒子。利用海鲜变质时会释放出硫化氢气体而与所制备的银纳米粒子薄膜反应生成硫化银黑色沉淀，使得本应是光亮的银层而变黑，从而监测海产品新鲜程度。该反应不可逆，即无法再通过低温使得海产品的外包装变回光亮的银层。工艺流程中，无需繁琐的步骤，流程简单易操作，可大规模制备，而且本发明的银纳米粒子薄膜可以与现有的海产品包装实现衔接，可以大规模制造、性价比高。
