| Abstract Scope |
Recently, one-dimensional lepidocrocite phase titanium oxide (1DL) has been discovered through a highly scalable and energy efficient synthesis. Interestingly, this phase is composed of individual nanofilaments that grow tens of nanometers long, but with cross-sections of only ~2 Ti-O bonds thick. Because of this remarkable dimensionality feature, 1DL nanofilaments may be used as individual "building blocks" to assemble various hierarchical structures. Through our work, we have observed a wide range of assemblies by simply injecting aqueous 1DL colloid into organic solvents of varied functionality and polarity. Ranging from highly compressible, purely inorganic hydrogels to paper and fabric-like materials, the 1DL structural features remain largely unchanged by XRD, Raman, and FTIR. As such, this work marks a critical discovery in the self-assembly of materials with remarkably different physical properties while maintaining their pure lepidocrocite phase titanium oxide-based fundamental character. |
