A porous superhydrophobic poly (vinyl chloride) surface was obtained by a simple approach. The water contact angle and the sliding angle of the superhydrophobic poly(vinyl chloride) surface were 154 +/- A 2.3A(0) and 7A(0), respectively. The porous superhydrophobic PVC surface remained superhydrophobic property in the pH range from 1 to 13. When the superhydrophobic PVC surface was immersed in water with the temperatures ranging from 5 A degrees C to 50 A degrees C for 1 h to 30 days, the water contact angle remained higher than 150A degrees. After outdoor exposure for 30 days, the contact angle still remained 150A(0).
