1. A foley catheter comprising:
a catheter body made of a first material comprising a first carbon nanotube polymer mixed with silicon;
wherein the catheter body is formed as a single layer with at least one fluid passage,
a foley balloon connected to the catheter body and configured to be inflated by a fluid introduced from outside, wherein the foley balloon is made of a second material comprising a second carbon nanotube polymer mixed with silicon, and
an insulating layer disposed solely between the catheter body and the foley balloon, the insulating layer configured to prevent electric current from flowing from the foley balloon to the catheter body,
wherein the first and second carbon nanotube polymers are polymerized with carbon nanotube and zinc oxide (ZnO), and
wherein the second material has a higher mixing ratio of the second carbon nanotube polymer than the first carbon nanotube polymer, and there is an electrical potential difference between the foley balloon and the catheter body.
