Nowadays, the subject of wettability still has received little attention in the scientific literature, especially in the cellular solids, despite its significant role in the pervasiveness of the water treatment. Herein, inspired by the mussel, a green method was developed to construct nano-/micro-structures on the multi-structural polypropylene (like the dense solids, big hollow, small hollow and hierarchical open/closed-cell porous structure) by the surface-adherent polydopamine. Moreover, the relationship between both surface chemical and physical (such as pore structure and size) properties of the porous media, and wettability were studied. Besides, water–glycerol mixture solutions with various viscosities were used to study the spreading and imbibition behavior in the porous polypropylene foams, and the surface free energy of the different cellular solids (before and after modification) was estimated by Owens-Wendt equation. More interestingly, different kinds of the super-wetting materials like super-amphiphilic and hierarchical super-hydrophilic/super-hydrophobic, etc., were successful prepared. Both fundamental theoretical and numerical analysis were also conducted to reveal the mechanism of the penetration or surface repellency toward a drop, and to predict the transport of fluids in porous media. We believe that this work may serve as a source of inspiration in designing other advanced functional materials.

如今，尽管润湿性在水处理的普及中起着重要作用，但在科学文献中，特别是在细胞固体中，润湿性仍然很少受到关注。在此，受贻贝启发，开发了一种绿色方法，通过表面在多结构聚丙烯上构建纳米/微结构（如致密固体，大空心，小空心和分层的开/闭孔多孔结构） -粘附的聚多巴胺。此外，研究了多孔介质的表面化学和物理性质（例如孔结构和尺寸）与润湿性之间的关系。此外，还使用了各种粘度的水-甘油混合溶液来研究多孔聚丙烯泡沫的扩散和吸收行为，并通过Owens-Wendt方程估算了不同细胞固体的表面自由能（改性前后）。更有趣的是，成功地制备了不同种类的超润湿材料，例如超两亲性和分级超亲水性/超疏水性等。还进行了基本的理论和数值分析，以揭示渗透或表面抗液滴性的机理，并预测流体在多孔介质中的传输。我们认为，这项工作可能会成为设计其他高级功能材料的灵感来源。，已成功准备。还进行了基本的理论和数值分析，以揭示渗透或表面抗液滴性的机制，并预测流体在多孔介质中的传输。我们认为，这项工作可能会成为设计其他高级功能材料的灵感来源。，已成功准备。还进行了基本的理论和数值分析，以揭示渗透或表面抗液滴性的机制，并预测流体在多孔介质中的传输。我们认为，这项工作可能会成为设计其他高级功能材料的灵感来源。
