The organic-inorganic composite coatings were prepared by organic/inorganic hybrid method based on PDMS and nano-CaCO3.Introducing an appropriate amount of CaCO3 nanoparticles to PDMS could significantly increase water contact angle of composite coating surface.The water contact angle increased from 113° to 158° by introducing CaCO3 nanoparticles to PDMS.The superhydrophobic coating showed excellent self-cleaning properties.Furthermore,the coatings prepared by this method exhibited simple procedure,no need special equipment,suitable for large area preparation and low production costs.Thus,the superhydrophobic self-cleaning coatings had practical value for wide application.
