The elastomer materials with hierarchical structure and suitable wettability are useful as biological surface model. In the present study, urethane resin and silicone resin elastomers with hierarchical rough surfaces were prepared and referred to as "fractal elastomers". We found a hierarchy of small projections that existed over larger ones on these surfaces. These elastomers were synthesized by transferring a fractal surface structure of alkylketene dimer. The rough structure enhanced the hydrophobicity and weakened friction resistance of the elastomer surfaces. These materials can be useful for artificial skin with biomimetic surface properties.
具有分级结构和合适润湿性的弹性体材料可作为生物表面模型。在本研究中，制备了具有分级粗糙表面的聚氨酯树脂和硅树脂弹性体，并将其称为“分形弹性体”。我们发现在这些表面上存在着一种小凸起的分级结构，小凸起位于大凸起之上。这些弹性体是通过转移烷基烯酮二聚体的分形表面结构合成的。这种粗糙结构增强了弹性体表面的疏水性并减弱了其摩擦阻力。这些材料可用于具有仿生表面特性的人造皮肤。
