- Abstract
The adhesion of hydrophilic coating on self-prepared hyper-slippery silicone catheter, hyper-slippery latex catheter and hydrophilic balloon dilation catheter is tested. The friction coefficient of uncoated, coated and immersed tubes are tested by friction coefficient tester for 30 times, and then they are stained with Congo red. The results show that the friction coefficient of coated tubes is decreased by 90% as compared to uncoated tubes. After chafing for 30 times, the friction coefficient of the coating is less than 0.1. The coating can be dyed uniformly and U2ZU1 1. It is revealed that the adhesion of the three self--prepared hydrophilic catheters are excellent.
