Rapid formation of ultrathin membrane by precipitation

This ongoing project studies the rapid formation of ultrathin membrane by precipitation. The membrane are formed directly on the coagulation bath and leads to a particular thickness profile on the order of tens of nanometers over centimeter squares. The birth of the membrane and its wrinkled final state are under current investigation.
