Characterization of hydrophobic properties of microstructures in complex geometries

Petition / Problem

The client needs to study the influence of the draft angle on the hydrophobic properties of different microstructures.

Objective 

Measure the contact angle in microstructured inclined areas.

ATRIA solution

Special tools were manufactured with which to tilt the samples and the appropriate areas were removed to be able to measure the contact angle in a good way. Once this was done, the variation of the contact angle due to the variation of the draft angle of the pieces was checked.
