作为优选的技术方案,所述步骤4)中纳米颗粒分散液的核纳米晶尺寸分布在10~100nm。
作为优选的技术方案,所述铋源为硝酸铋、氯化铋其中的一种;氟源为氟化铵,氢氟酸,氟化钠其中的一种。
作为优选的技术方案,所述步骤3)在快速搅拌下,将硝酸铋的乙二醇溶液缓慢倾倒入氟化铵的乙二醇溶液中;
作为优选的技术方案,所述步骤6)中水溶性核壳纳米晶质量占柔性透明辐射防护膜总质量的大于60%。
作为优选的技术方案,所述步骤6)中成膜法包括滴涂、旋涂、印刷其中的一种。
作为优选的技术方案,所述步骤6)中衬底材质包括聚丙烯,玻璃,聚四氟乙烯、透明陶瓷其中的一种。
本发明还公开了一种基于铋化合物的柔性透明辐射防护膜在医疗、光电器件与陶瓷领域中的应用。
由于采用了上述技术方案一种基于铋化合物的柔性透明辐射防护膜制备方法及其应用,包括以下步骤:1)反应物铋源Bi(NO3)3·5H2O与氟源NH4F按摩尔比1:3组成,反应溶剂为乙二醇;2)将步骤1)称取的反应物铋源跟氟源分别在乙二醇中溶解,持续搅拌,至溶液呈透明状态;3)在搅拌状态下,将含有铋源的乙二醇溶液跟氟源的乙二醇溶液混合,反应持续1分钟;4)将步骤3)的反应产物,离心分离得到沉淀,分散在去离子水中,得到纳米颗粒分散液;5)将步骤4)所述的纳米颗粒分散液与聚乙烯醇水溶液按不同质量比混合,加入0.1v%甘油,搅拌混合均匀后,得混合水溶胶;6)取步骤5)中步骤中所述混合水溶胶1~100v%通过成膜法用到衬底上,放入烘箱,30~100℃条件干燥,得到柔性透明辐射防护膜。
本发明的优点:
本发明通过将纳米颗粒分散于水中,形成稳定分散液,保证了纳米颗粒与聚乙烯醇混合所得溶胶的均匀性,避免纳米颗粒因团聚导致的复合膜透明度下降,实现在可见光波段(400-800nm)实现70%以上的光透过率;并在微量甘油的作用下,实现辐射防护膜柔性的长期稳定性。
本发明在保持了柔性透明辐射防护膜的高透明度的前提下,实现了对X射线的有效吸收,减少X射线的透过率,实现了对辐射敏感成分的防护,尤其可保护人员免受核电和工业设施、实验室以及医疗中心的辐射影响。
