Abstract: The invention discloses a durable super-hydrophobic fabric and a preparation method thereof. The preparation method comprises the following steps: soaking a fabric into a mixed solution of tetraethoxysilane and hydroxy-terminated polydimethylsiloxane; taking out the fabric and then placing it into a closed container filled with a hydrochloric acid solution and above the liquid level of the hydrochloric acid solution; reacting for 0.5-2 h under the temperature of 30-60 DEG C. to give the durable super-hydrophobic fabric. The fabric prepared according to the invention has a water drop surface static contact angle of more than 150° such that the water drop is easy to roll on the surface of the fabric, and has excellent chemical stability and mechanical durability. In addition, the preparation process is simple and pollution-free.
