Description
技术领域：
本发涉及一种快速检测二氧化硫的蛋白石光子晶体水凝胶制备方法和应用
，属于有机物制造技术领域。
背景技术
二氧化硫（化学式SO2）是最常见、最简单的硫氧化物。大气主要污染物之一。火山爆发时会喷出该气体，在许多工业过程中也会产生二氧化硫。由于煤和石油通常都含有硫元素，因此燃烧时会生成二氧化硫。当二氧化硫溶于水中，会形成亚硫酸。若把亚硫酸进一步在PM2.5存在的条件下氧化，便会迅速高效生成硫酸（酸雨的主要成分）。这就是对使用这些燃料作为能源的环境效果的担心的原因之一。因此, 实现对二氧化硫（化学式SO2）是最常见、最简单的硫氧化物。大气主要污染物之一。火山爆发时会喷出该气体，在许多工业过程中也会产生二氧化硫。由于煤和石油通常都含有硫元素，因此燃烧时会生成二氧化硫。当二氧化硫溶于水中，会形成亚硫酸。若把亚硫酸进一步在PM2.5存在的条件下氧化，便会迅速高效生成硫酸（酸雨的主要成分）。这就是对使用这些燃料作为能源的环境效果的担心的原因之一。的准确、实时地检测比较困难。二氧化硫的检测方法有紫外可见光谱法、顺磁共振波谱法、荧光探针法、法拉第磁旋转光谱法、电化学检测法、化学发光法等。化学发光法定量检测的是二氧化硫与臭氧 (O3) 反应产生的发光强度, 而O3与干扰气体亦会发生反应并产生光信号, 致使检测信号值偏大。因此, 如何消除杂质气体的干扰, 实现高精准度的检测二氧化硫含量成为关键,
光子晶体是指具有光子带隙（PhotonicBand-Gap，简称为PBG）特性的人造周期性电介质结构，有时也称为PBG光子晶体结构。所谓的光子带隙是指某一频率范围的波不能在此周期性结构中传播，即这种结构本身存在“禁带”。其是一类新兴的光学材料,可以衍射特定波长的光,从而显示出特定的结构色,可用于生化物质的裸眼检测。在光子晶体中,周期性排列的重复结构单元以光波长量级为尺度,根据其重复结构循环维数,可分为一维、二维和三维光子晶体。光子晶体的制造方法主要有精密机械加工法、半导体制造技术、胶体自组装法等。作为一种新型的信息传导材料,光子晶体已成为学术界的一个研究热点。
发明内容：
为了解决上述问题，本发明提供一种快速检测二氧化硫的蛋白石光子晶体水凝胶的生产工艺,该工艺生产流程简单,操作方便,不使用有毒有害溶剂,而且还具有生产成本低,产品纯度高,适合于工业化生产等特点,不仅可以有效降低能耗,而且可以彻底解决有机溶剂残留问题,绿色安全环保。一种快速检测二氧化硫的蛋白石光子晶体水凝胶制备方法和应用，包括如下步骤：
（1）利用垂直沉降自组装方法制备蛋白石光子晶体模片；
（2）向蛋白石光子晶体中空隙处填充含有印迹分子聚丙烯酰胺溶液，引发光聚合；
作为优选：所述步骤1中蛋白石光子晶体模片的制备方法为：
1)将载体基质用去离子水超声清洗后，在溶液中浸泡7-8小时后，用去离子水和乙醇清洗干净，高温烘干；
2)将二氧化硅(SiO2)微球均匀分散到无水乙醇中，形成胶体分散体系，SiO2质量分数1.0～4 .0％，将上述制备的亲水化基质直插入二氧化硅溶液中，采用垂直自组装的方式，在25～35℃恒温密闭条件下静置至乙醇挥发完毕，制备得到蛋白石光子晶体结构模片。
作为优选：所述步骤2中预聚溶液和引发光聚合为：将模板分子、功能单体、交联剂、引发剂溶于溶剂中，充分混合后得到预聚合溶液。所述模板分子为蛋白石晶体结构模片、功能单体为聚丙烯酰胺、交联剂为乙二醇二甲基丙烯酸酯、引发剂为偶氮二异丁氰、 溶剂为甲醇-水混合溶液，将膜放置于光子晶体模片上，利用毛细管作用，将预聚合溶液采用后填充技术 均匀铺满膜片与光子晶体的空隙，然后在紫外灯照射下紫外引发聚合6-10小时，得到聚丙烯酰胺蛋白石光子晶体。
本发明检测二氧化硫的方法，其中，在常温下将所述的光子晶体触碰含有二氧化硫溶液，随着印记分子溶于溶剂，与水凝胶微球内部发生溶质交换， 光子带隙发生红移，颜色随印记分子浓度发生不同的改变，越深则越浓。
本发明的创新点提供了一种用于检测二氧化硫的光子晶体凝胶材料,包括聚丙烯酰胺凝胶和包埋于所述凝胶中的光子晶体,所述凝胶直接或间接地化学接枝苯硼酸基团,其中,所述光子晶体为二维光子晶体或三维光子晶体。本发明还提供了基于所述光子晶体凝胶材料的二氧化硫检测方法,利用颜色模式分析法,将光子晶体凝胶材料检测二氧化硫溶液后显示的颜色信息转化成二氧化硫浓度信息。本发明提供的二氧化硫检测方法可高选择性、灵敏、便捷以及可视化地定性或定量检测二氧化硫浓度,为二氧化硫监控提供了新的非创伤性检测方法。
