Highly interconnected hydrophilic polymers were prepared through the polymerisation of (paraffin-oil)-in-water emulsion templates using internal phases below 74 vol%. These were stabilised by Tween 85 and contained acrylamide and N,N/-methylene bisacrylamide, as monomers, in the continuous water phase. The emulsification energy was increased, resulting in increased contact between emulsion droplets, allowing open cellular and highly interconnected structures to be achieved. This was coupled with a reduction in the internal phase volume allowing the obtainment of highly interconnected materials with excellent mechanical properties under compression, producing a Young’s modulus of 490 ± 90 MPa for a material with 36 ± 3% porosity. It was also found that the morphology of these materials could be altered through variations in the internal phase volume, the surfactant level and the emulsification energy. These porous polymers also possessed quite different behaviours in different solvent environments suggesting applications in controlled release or as rigid absorbents.

从具有改进机械性能的乳液模板制备高度互连的亲水聚合物

高度互连的亲水聚合物是通过使用低于 74 vol% 的内相的（石蜡油）水包乳液模板聚合制备的。这些由吐温 85 稳定并在连续水相中包含丙烯酰胺和 N,N/-亚甲基双丙烯酰胺作为单体。乳化能量增加，导致乳液液滴之间的接触增加，从而实现开放的细胞和高度互连的结构。这与内相体积的减少相结合，允许获得在压缩下具有优异机械性能的高度互连的材料，对于具有 36 ± 3% 孔隙率的材料产生 490 ± 90 MPa 的杨氏模量。还发现这些材料的形态可以通过内相体积、表面活性剂水平和乳化能的变化而改变。这些多孔聚合物在不同的溶剂环境中也具有完全不同的行为，表明可应用于控释或作为刚性吸收剂。
