Title |
Developing a superhydrophobic, transparent coating for medical device applications |

Description |
The use of laparoscopes and endoscopes has revolutionized the field of medicine and surgery-allowing for quicker and more non-invasive procedures. One major drawback of using laparoscopes is the ease of which debris and condensation can collect on the lens and obstruct the surgeon's view. This paper details a method of developing a non-toxic, superhydrophobic (contact angle greater than 150 degrees) and transparent (transmittance greater than 85 percent) coating that is applied to a lens and keeps debris off and condensation from forming. The coatings, made out of various concentrations and layers of a fumed silica so 1-gel, were topped with a solution o f hydrophobic methyltriethoxy silane. Although most of the coatings produced superhydrophobic surfaces, transmittance decreased as contact angle increased. The decrease in transmittance was far too great for any of the coatings to meet the design specifications. However, the potential for success in future work is promising. |
