- Abstract:
- The feasibility of automated, high-throughput
contact-angle measurements is demonstrated using a modified
commercial contact-angle measuring apparatus. Droplets
are automatically dispensed, analyzed and aspirated.
The system automatically measures more than 100 contact
angles per hour using two test liquids, and calculates surface
energies using the equation of state method. A library of
poly(2-oxazoline) homo- and block copolymers was investigated.
Polymers with a 2-nonyl-2-oxazoline block were
found to have considerably lower surface energies.
