We report the design and testing of a custom-built experimental setup for dip-coating from volatile solutions under microgravity conditionsonboard an aircraft. Function and safety considerations for the equipment are described. The equipment proved to work well, both concerningthe safety and the preparation of thin films. No leakage of the solvents, nor the solvent vapors, was detected, not even in a situation with afluctuating gravitational field due to bad weather conditions. We have shown that the equipment can be used to prepare thin films of polymerblends, relevant for organic solar cells, from solution in a feasible procedure under microgravity conditions. The prepared films are similar tothe corresponding films prepared under 1 g conditions, but with differences that can be related to the absence of a gravitational field duringdrying of the applied liquid coating. We report on some introductory results from the characterization of the thin films that show differencesin film morphology and structure sizes. |
