水-油界面不平衡是实现油水乳液破乳的关键。传统膜通常是依赖较高的跨膜压力破坏界面平衡而实现破乳。本文提出了可自然、快速地破坏水-油界面平衡的“接触破乳”的概念,开发了一种对有机组分具有高通量的新型破乳分离膜。具体制备过程分为两步,首先通过真空辅助抽滤法在聚四氟乙烯(PTFE)基底上组装ZIF-8@rgO微球(ZgS)层,再采用聚二甲基硅氧烷(PDMS)交联溶液中进行固定化处理。由于ZgS表面为微纳米阶层结构,所制备的ZIF-8@rgO@PDMS/PTFE(ZgPP)膜表面展现出超疏水性特性,当表面活性剂稳定的油包水乳液接触到膜表面时,微纳结构的超疏水膜表面会引起水-油界面不平衡。ZgPP膜对油包水乳液具有良好的分离破乳性能,在0.15 bar(15 kPa)的低跨膜压力下,分离效率可以达到99.57%,通量可达到2254 L·m^(-2)·h^(-1),且对于表面活性剂稳定的纳米级甲苯-水乳剂(平均液滴尺寸为57 nm)的体系也可以实现破乳分离。“接触破乳”概念的提出有望为开发新一代油包水乳液分离的破乳膜提供新的思路。

针对传感网络中的入侵数据进行查询,为提高网络数据管理性能和可靠性。由于在进行入侵数据查询时,需要设定固定的过滤器阈值,使得对入侵数据的遍历不全面。传统的查询算法主要通过收集各节点入侵数据,进行数据查询,没有设置过滤器阈值,导致查询出现冗余数据,查询精度低。提出分簇算法的传感网络中入侵数据查询的改进方法。在传统算法的基础上将网络划分为不同的簇,筛选出各个簇的簇头节点,由簇头节点将数据汇聚至Sink节点,并设置过滤器阈值对汇聚至Sink节点上的入侵数据进行过滤,最后利用入侵数据间的关联特征遍历和收集全部网络中和查询数据关联性较强的入侵数据,生成最终的查询结果。仿真结果证明,基于分簇的传感网络中入侵数据查询方法抗干扰性较强,同时提高了入侵数据查询的精度和效率。
