With the continuous progress and development of society, the supply of fresh water is always in a continuously high demand no matter daily household or industrial activity, however, the shortage of water resources has become one of the problems to be solved urgently in the world increasingly. Today, approximately 40 hundred million people face severe water shortage conditions. To solve the problem of water shortage, there are two methods, one is to add fresh water, such as can be obtained by sea water desalination, treatment and from the air; the other is water saving. It is statistical that toilet flushing accounts for 20% of the total domestic water in a domestic life, and approximately 1400 billion liters of fresh water are used to flush toilets worldwide. And about 26 million people in 70 million worldwide cannot obtain basic public health services because of water shortage. Therefore, there has been an increasing interest in reducing the amount of water used to flush toilets. In the daily use of sanitary ware, residues, scales, urine scale and the like are easily accumulated on the wall of the sanitary ware, so that a large amount of water resources are mainly used for flushing the sanitary ware. If a low viscosity, low surface energy superhydrophobic, self-cleaning sanitary fixture could be prepared, the residue accumulated on the walls would be well rinsed clean. Self-cleaning means that pollutants, water drops and dust can automatically fall off or be degraded under the action of external force such as gravity, rainwater, wind power and the like, and the key of self-cleaning is to realize the super-hydrophobicity of the material.
