In this paper, we report a microcapsule embedded PNIPAN in P (TPC-EDA) shell and it can be regarded as an interpenetrating polymer network (IPN) structure, which can accelerate the penetration of oily substances at a certain temperature, and the microcapsules are highly monodisperse and dimensionally reproducible. The proposed microcapsules were fabricated in a three-step process. The first step was the optimization of the conditions for preparing oil in water emulsions by microfluidic device. In the second step, monodisperse polyethylene terephthaloyl-ethylenediamine (P(TPC-EDA)) microcapsules were prepared by interfacial polymerization. In the third step, the final microcapsules with poly(N-isopropylacrylamide) (PNIPAM)-based interpenetrating polymer network (IPN) structure in P(TPC-EDA) shells were finished by free radical polymerization. We conducted careful data analysis on the size of the emulsion prepared by microfluidic technology and used a very intuitive functional relationship to show the production characteristics of microfluidics, which is rarely seen in other literatures. The results show that when the IPN-structured system swelled for 6 h, the adsorption capacity of kerosene was the largest, which was promising for water-oil separation or extraction and separation of hydrophobic drugs. Because we used microfluidic technology, the products obtained have good monodispersity and are expected to be produced in large quantities in industry.

聚对苯二甲酰乙二胺-IPN-聚(N-异丙基丙烯酰胺)微胶囊的可控制备及油水分离性能。

在本文中，我们报道了一种在 P (TPC-EDA) 壳中嵌入 PNIPAN 的微胶囊，它可以看作是互穿聚合物网络 (IPN) 结构，可以在一定温度下加速油性物质的渗透，并且微胶囊是高度单分散和尺寸重现性。所提出的微胶囊是在三步过程中制造的。第一步是优化通过微流控装置制备水包油乳液的条件。在第二步中，通过界面聚合制备单分散聚对苯二甲酰基乙二胺 (P(TPC-EDA)) 微胶囊。在第三步中，通过自由基聚合完成在 P(TPC-EDA) 壳中具有基于聚 (N-异丙基丙烯酰胺) (PNIPAM) 的互穿聚合物网络 (IPN) 结构的最终微胶囊。我们对微流控技术制备的乳液的大小进行了细致的数据分析，用非常直观的函数关系展示了微流控的生产特性，这在其他文献中很少见。结果表明，当IPN结构体系溶胀6 h时，对煤油的吸附量最大，有望用于水油分离或疏水性药物的萃取分离。由于我们采用了微流控技术，所获得的产品具有良好的单分散性，有望在工业上大批量生产。这在其他文献中很少见。结果表明，当IPN结构体系溶胀6 h时，对煤油的吸附量最大，有望用于水油分离或疏水性药物的萃取分离。由于我们采用了微流控技术，所获得的产品具有良好的单分散性，有望在工业上大批量生产。这在其他文献中很少见。结果表明，当IPN结构体系溶胀6 h时，对煤油的吸附量最大，有望用于水油分离或疏水性药物的萃取分离。由于我们采用了微流控技术，所获得的产品具有良好的单分散性，有望在工业上大批量生产。
