Before each experiment, Langmuir/Langmuir-Blodgett troughs were cleaned with chloroform, ethanol, and ultrapure water and then left to dry. The interface was cleaned using a Teflon nozzle, repeating the process until the surface pressure increase during compression was below 0.1 mN•m⁻¹. A NESLAB RTE 7 thermostat was used to maintain the desired temperature.
