摘要： Described herein relates to apparatus and method for developing a free-standing zwitterion-promoted hybrid clay film having excellent ionic conductivity, thermal stability, and/or chemical stability. As such, in an embodiment the clay film apparatus may comprise biocompatible materials, including but not limited to clay and trimethyl glycine (hereinafter “TMG”), also known as a zwitterion. Additionally, in an embodiment, the clay film apparatus may be synthesized utilizing a simple method for making a free-standing flexible, non-polymeric clay film. Moreover, in an embodiment, the prepared film's increased porosity, superior thermal and chemical stability, electrically insulating, and ionic conductivity, as compared to clay films known in the art, may make it an excellent material for energy applications as an ion-conducting membrane. The applications may include but are not limited to battery separators, electrolyte membranes in fuel cells, and solid electrolyte membranes in batteries.

摘要： Methods are disclosed for producing an organic functionalized solid inorganic substrate, a surface of the inorganic substrate comprising a hydroxide and/or an oxide comprising an element M, the element M being a metal or a metalloid. The method includes drying the surface; optionally removing protons from the surface; and contacting the surface with an organometallic reagent comprising at least one organic functional moiety, thereby obtaining the organic functionalized inorganic substrate, the at least one organic functional moiety being attached to the element M of the hydroxide and/or the oxide by means of a direct M-C bond. The drying step includes contacting the surface with a flow comprising an inert gas. The organic functionalized inorganic substrate obtained by the method may be used as a membrane, a catalyst, a sorbent, a sensor or an electronic component, or as a substrate in filtration, adsorption, chromatography and/or separation processes.
