Due to the temperature non-uniformity of the solution surface resulting from the thermal convections, water condenses heterogeneously. The heterogeneous condensation of water droplets induces the formation of irregular-arrangement of domains in the ordered structure of microporous films. In order to evaluate the effect of gravity on the formation of honeycomb-patterned films, we have made microgravity experiments. Even under microgravity, we successfully prepared honeycomb-patterned films. And interestingly, some samples have multi-layered uniform microporous structures, which are formed with vanishing the relative density effect of solvent and water droplets. It is suggested that the microgravity affects the formation of honeycomb-patterned films considerably., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: DS1440092000}, pages = {3--10}, title = {Effect of Microgravity on the Formation of Honeycomb-patterned Films by Dissipative Processes}, volume = {31}, year = {2014} }
