Abstract
The present invention relates to a preparation method of a tube and a transplantable polymer tube prepared by such method, which includes modifying the inner surface of a tube using plasma. A preparation method of a tube may include preparing a tube, modifying the inner surface of the tube using microplasma so as to have reactivity, forming a thin film layer on the modified surface of the tube to prevent aging or impart adhesiveness, and modifying the surface of the thin film layer using microplasma so as to enhance cell adhesion thereon.
