石松花粉素，一种天然共聚物，在高静水压（10 GPa）下显示出优异的稳定性，通过原位高压同步辐射源傅里叶变换红外光谱测定。根据孢粉素的组分化合物评价该稳定性：对香豆酸、根皮酸、阿魏酸、棕榈酸和癸二酸，其代表额外的n-酸和n-二酸组分。这种高稳定性归因于这些组分之间的相互作用，而不是任何一种分子组分的特殊稳定性。这项研究提出了一种仿生解决方案，用于制造能够承受高压的聚合物材料，用于航空，血管自体移植，弹道学和轻质保护材料。
Lycopodium sporopollenin, a natural copolymer, shows exceptional stability under high hydrostatic pressures (10 GPa) as determined by in situ high pressure synchrotron source Fourier transform infrared spectroscopy. This stability is evaluated in terms of the component compounds of the sporopollenin: p-coumaric acid, phloretic acid, ferulic acid, and palmitic and sebacic acids, which represent the additional n-acid and n-diacid components. This high stability is attributed to interactions between these components, rather than the exceptional stability of any one molecular component. This study proposes a biomimetic solution for the creation of polymer materials that can withstand high pressures for a multitude of uses in aeronautics, vascular autografts, ballistics, and light-weight protective materials.
