Abstract
Presently described are methods of inhibiting water vapor adsorption of a powder and methods of storing a powder at increased humidity level. The methods comprise providing adding discrete hydrophobic nanoparticles to a plurality of particles.
Claims21
A method of inhibiting water vapor adsorption of a powder comprising:
- providing a plurality of particles;
- adding discrete hydrophobic nanoparticles;
- and
- exposing the particles to a relative humidity of least 15%;
- wherein the particles combined with the hydrophobic surface modified nanoparticles have a lower water vapor adsorption than the plurality of particles alone.
