Abstract
Official abstract text for this publication.
In some embodiments, the present invention provides amphiphilic nanosheets that comprise lamellar crystals with at least two regions: a first hydrophilic region, and a second hydrophobic region. In some embodiments, the amphiphilic nanosheets of the present invention also comprise a plurality of functional groups that are appended to the lamellar crystals. In some embodiments, the functional groups are hydrophobic functional groups that are appended to the second region of the lamellar crystals. In some embodiments, the lamellar crystals comprise α-zirconium phosphates. Additional embodiments of the present invention pertain to methods of making the aforementioned amphiphilic nanosheets. Such methods generally comprise appending one or more functional groups to a stack of lamellar crystals; and exfoliating the stack of lamellar crystals for form the amphiphilic nanosheets.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of making an amphiphilic nanosheet, wherein the method comprises: appending one or more functional groups to a stack of lamellar crystals; and exfoliating the stack of lamellar crystals to form the amphiphilic nanosheets, wherein the functional groups comprise octadecyl isocyanate, wherein the nanosheets comprise at least two regions, wherein the first region is hydrophilic, and wherein the second region is hydrophobic.
