Small wax sculptures on plant surfaces are responsible for a variety of functions, including the maintenance of sability, self-cleaning properties, prevention of insect attachment and reflection of light. Here we report on a method for using recrystallized plant wax crystals on flat technical surfaces for generating micro- and nanopatterned polymers with particular functions. Therefore a more than 4-thousand year old replica technique called the "lost wax technique" has been adapted for reproduction of complex, high aspect ratio surfaces and the large scale reproduction of micro- and nanopatterned surfaces. Highly ordered pyrolytic graphite substrates, covered with perpendicularly oriented platelets formed by the primary alcohol octacosan-1-ol, the main component of wheat (Triticum aestivum) leaf waxes, were used as templates to make an epoxy resin surfaces with high aspect ratio platelets 400-700 nm wide and 10-50 microm thick. The technique holds great promise on the reproduction of micro- and nanopatterned surfaces.
植物表面的微小蜡质雕塑具有多种功能，包括维持稳定性、自清洁特性、防止昆虫附着以及反射光线。在此，我们报告一种在平面技术表面使用重结晶植物蜡晶体来生成具有特定功能的微纳图案聚合物的方法。因此，一种已有四千多年历史的复制技术——“失蜡法”，已被用于复杂的高纵横比表面的复制以及微纳图案表面的大规模复制。高度有序的热解石墨基板，覆盖着由小麦（Triticum aestivum）叶蜡的主要成分伯醇二十八烷 -1-醇形成的垂直取向薄片，被用作模板来制作具有高纵横比薄片的环氧树脂表面，这些薄片宽400 - 700纳米，厚10 - 50微米。该技术在微纳图案表面的复制方面具有巨大潜力。
