- Аннотация: There is typical drawback when nano-sized polymer structures are deposited on a substrate surface from their solutions in liquid solvents. The problem is related to the influence of surface tension forces and capillary forces, which are able to reorganize dramatically the structures being deposited. The most critical is the very moment of solvent removal. Therefore, it seems to be very promising to perform systematic studies of individual macromolecules, supramolecular structures and ultrathin films as deposited directly from such a solvent, which is not a liquid, i.e. sc CO2. In that case at any stage of the deposition process there is never any coexistence on the substrate of the structures being deposited and of thin liquid film or droplets of a drying liquid solvent. Thus, one may hope that the morphology of deposited objects is not disturbed at the solvent removal stage. Scanning force microscopy is a convenient tool to study the morphology of such nanosized polymer structures directly deposited from their solutions in sc CO2.
