Porous polymers are of great interest in potential energy storage and environmental remediation applications. However, traditional fabrication methods are either time-consuming or energy-consuming and deteriorate the mechanical strength of polymer materials. In this study, polymerization-induced phase separation was used to realize the template-free fabrication of superflexible macroporous polymers. Since the solvent is also used as a porogen, this method can be widely used to synthesize several porous polymers by carefully choosing the solvent and monomer. Compared to nonstructured polymers, the prepared macroporous polymers exhibited enhanced mechanical strength, superflexibility, multicompressibility, and bending properties. Along with hydrophobicity/oleophilicity and macroporous structures, the as-prepared porous polymers demonstrated controllable oil absorbability and release; furthermore, after infusing with lubrication liquid, these materials can be used as antiwaxing materials. The elastic porous polymers prepared using this simple and universal method show great potential for various applications, including controlled drug release, antiwaxing, and lubrication.

具有增强的吸油性和抗打蜡性能的弹性大孔聚合物的制备。

多孔聚合物在潜在的能量存储和环境修复应用中非常受关注。然而，传统的制造方法既费时又耗能，并且降低了聚合物材料的机械强度。在这项研究中，聚合诱导相分离被用来实现超柔性大孔聚合物的无模板制备。由于溶剂也用作致孔剂，因此通过仔细选择溶剂和单体，该方法可广泛用于合成多种多孔聚合物。与非结构化聚合物相比，制得的大孔聚合物表现出增强的机械强度，超柔韧性，多重压缩性和弯曲性能。连同疏水性/亲油性和大孔结构，所制备的多孔聚合物表现出可控的吸油性和释放性。此外，在注入润滑液后，这些材料可以用作抗打蜡材料。使用这种简单而通用的方法制备的弹性多孔聚合物在各种应用中显示出巨大的潜力，包括受控的药物释放，抗打蜡和润滑。
