摘要：

自然界中有一类神奇的超浸润，如荷叶上水珠和水黾轻功“水上漂”等，这是材料表面特异的微纳超级结构和活性物质所致。效法自然，合成了两种超浸润界面剂和一种开关型的Cu（OH）2@ZIF-8纳米网膜。从自然植物–日常应用–科技发展，由浅入深，全方位地科普了神奇而又不乏科学趣味的自然现象（化学变脸），以激发青少年对于自然、科学的兴趣。

关键词: 超浸润, 微纳结构, 开关型网膜, 荷叶

Abstract:

There is a kind of magical super-infiltration phenomenon in nature, which is caused by the special micro-and nano-structures on its surface. For example, the droplets of water on lotus leaves after rain, and the lightness skill of water striders float on the water. In the manuscript, two simple super-infiltrative interfacial agents and a switch-type Cu(OH)2@ZIF-8 nanomesh were synthesized by simulating the micro-interface structure of natural plants. The omni-directional popularization of science is a magical and interesting natural phenomenon to stimulate teenagers' interest in nature and science.
