Description
Technical field
The present invention relates to a kind of preparation methods of automatically cleaning plastic carpet, belong to new material technology field.
Background technique
In recent years, the super-hydrophobic phenomenon of leaf surface of plant attracts attention.The so-called super-hydrophobic ability of plant is exactly
Plant leaf surface has significant hydrophobic, desorption, anti-sticking, self-cleaning function etc..Lotus " mud is without contaminating out " is exactly because of its table
Face has one layer of based superhydrophobic thin films, can make it have self-cleaning function.Scientist by super-hydrophobic lotus leaf surface into
Row observation, they have found that lotus leaf surface micro-nano dual structure is to cause the basic reason of lotus leaf surface ultra-hydrophobicity.More than
