METHOD FOR FORMING SUPERHYDROPHOBIC COATING LAYER USING PDMS AND MICROPOWDERS

摘要

The present invention relates to a superhydrophobic coating method using polydimethylsiloxane (PDMS) and micro powder and, more specifically, to a superhydrophobic coating method using PDMS and micro powder, thinly coating a PDMS solution on a target surface and applying a sufficient amount of micro powder on a surface of the PDMS before curing, so as to form a surface structure capable of maximizing hydrophobicity (superhydrophobicity equal to or higher than 150° of a water droplet contact angle) as the PDMS is coated on a surface of the micro powder through a following curing process. According to the present invention, the PDMS is structured with a simple process and inexpensive materials to form a large area superhydrophobic surface and, for example, a water transfer efficiency is able to be largely increased when the present invention is applied on an inner surface of a water transfer pipe, thereby being able to be widely applied to various fields requiring superhydrophobic coating.
