Spontaneous Formation of Inorganic Paper-Like Materials


  • We thank the Geosciences and Biosciences Division of the Office of Basic Energy Sciences, Office of Science, U.S. Department of Energy, Office of Basic Energy Science for support of this research, and Dr. Frank Galasso for suggestions. We would like also to acknowledge Mr. Jim Romanow for providing access to their FESEM facilities in the Department of Physiology and the Neurobiology Department, University of Connecticut, and the Institute of Materials Science at of Physiology and the Neurobiology Department, University of Connecticut for the use of the microscopy facilities.


Paper-like membranes with a hierarchical microstructure (see Figure) are created from single-crystal cryptomelane-type manganese oxide (OMS-2) nanowires that aggregate and align spontaneously to self-organize into 2D arrays. The versatile material remains malleable, and can be written on, even under cryogenic conditions.
