Abstract
The present invention relates to a polymer composite for ureteral insertion, a method for preparing the same, and a ureteral stent using the same, and, in particular, to: a polymer composite for ureteral insertion in which the surface of a polymer substrate used in a ureteral stent is treated with plasma to improve the hydrophobicity of the surface, and thus, formation of stones on the surface of the stent can be prevented; a method for preparing the same; and a ureteral stent using the same.
Claims21
A polymer composite for ureteral insertion, the polymer composite comprising:
- a polymer substrate;
- and
- a coating layer provided on at least one surface of the polymer substrate,
- wherein the coating layer has a C atom in an amount of 78 at. % or greater and 82 at. % or less and an O atom in an amount of 13 at. % or greater and 17 at. % or less, which are detected by an analysis using an XPS analysis method.
