Abstract

It was shown for the first time that open microcapsules 1-5 µm in size with Mn3O4 walls and unique morphology are formed as a result of spraying an aqueous MnSO4 solution onto the surface of an alkali solution. The walls have a thickness of 80-120 nm and consist of an array of Mn3O4 nanosheets with a thickness of 2-3 nm, oriented predominantly in the radial direction towards the center of the microcapsule. There is a special rim with a height of 100-200 nm around the hole of the most microcapsules, which can be a kind of ‘ground’ when fixing such microcapsules on the surface of a substrate in the process of application by the Langmuir-Schaefer technique.
