PolyHIPEs are an important class of porous polymers with well-defined hierarchical porosity and tunable morphology. However, the insufficient mechanical properties arise due to high volume of voids bringing difficulties in applications. In this study, polyHIPEs with tailored morphological and mechanical properties were prepared by using a monoterpene for the first time. In this respect, copolymerization of β-myrcene with several comonomers within water-in-oil (w/o) high internal phase emulsions (HIPEs) has been extensively investigated. Accordingly, combining β-myrcene and ethylene glycol dimethacrylate (EGDMA) in polyHIPE structure was demonstrated as a successful approach for tailoring the morphology, as well as the mechanical strength. PolyHIPEs with cavities between 1.09 and 3.55 μm were obtained by changing the ratio of β-myrcene in the continuous phase of HIPEs. Moreover, resulting polyHIPEs have found to have improved mechanical strength. The highest compressive modulus achieved for the obtained monoliths was determined to be 38.8 MPa. Graphical abstract

β-月桂烯高内相乳液合成聚HIPEs

PolyHIPE 是一类重要的多孔聚合物，具有明确的分级孔隙率和可调节的形态。然而，由于大量空隙给应用带来困难，导致机械性能不足。在这项研究中，首次使用单萜制备了具有定制形态和机械性能的聚 HIPE。在这方面，β-月桂烯与几种共聚单体在油包水 (w/o) 高内相乳液 (HIPE) 中的共聚已得到广泛研究。因此，将 β-月桂烯和乙二醇二甲基丙烯酸酯 (EGDMA) 结合在聚 HIPE 结构中被证明是一种成功的调整形态以及机械强度的方法。空腔在 1.09 和 3 之间的 PolyHIPE。通过改变 HIPEs 连续相中 β-月桂烯的比例获得 55 μm。此外，已发现所得聚HIPE具有改进的机械强度。获得的整料获得的最高压缩模量确定为 38.8 MPa。图形概要
