Abstract

The present invention relates to a coating composition that can produce an article having an inner surface and an outer surface, both of which are slippery, and a method for preparing the same. By using the coating composition according to the present invention, it is possible to produce the article having the inner surface and the outer surface, both of which are slippery, only with a simple process of molding and curing a polymer resin by the technique of the prior art. The article produced using the coating composition of the present invention can solve an ice removal on a surface of the machinery such as an aircraft and an automobile, a biofouling problem in a blood vessel, a problem requiring self-cleaning, and the like, and thus can be used in various industries.
