Containerless synthesis of amorphous and nanophase organic materials

摘要

The invention provides a method for producing a mixture of amorphous compounds, the method comprising supplying a solution containing the compounds; and allowing at least a portion of the solvent of the solution to evaporate while preventing the solute of the solution from contacting a nucleation point. Also provided is a method for transforming solids to amorphous material, the method comprising heating the solids in an environment to form a melt, wherein the environment contains no nucleation points; and cooling the melt in the environment.

主权项

1. A method for producing neat amorphous compounds, the method comprising:
a. creating a solution containing a solute material to be amorphized, wherein the solute is dissolved in a solvent; and b. while preventing the solution from contacting a solid surface, allowing at least a portion of the solvent to evaporate at a rate sufficient to prevent crystallization of the solute, such that the solute is between 90 and 100 percent amorphous, wherein evaporation occurs at ambient pressure.
