Abstract
Nanoparticle inks and powders are sintered using an applied mechanical energy, such as uniaxial pressure, hydrostatic pressure, and ultrasonic energy, which may also include applying a sheer force to the inks or powders in order to make the resultant film or line conductive.
Claims21
A method for making a material conductive comprising:
- depositing a film of nanoparticles on a substrate;
- and
- performing a mechanical sintering process at room temperature on the film in a manner that applies shearing forces to the film resulting in the film of nanoparticles possessing a property of conductivity greater than before the mechanical sintering process is performed.
A method for making a material conductive comprising:
- depositing a film of nanoparticles on a substrate;
- and
- performing a mechanical sintering process at room temperature on the film in a manner that applies shearing forces to the film resulting in the film of nanoparticles possessing a property of conductivity greater than before the mechanical sintering process is performed, wherein the mechanical sintering process comprises physically pressing a spatula against the film of nanoparticles.
A method for making a material conductive comprising:
- depositing a film of nanoparticles on a substrate;
- and
- performing a mechanical sintering process on the film in a manner that applies shearing forces to the film resulting in the film of nanoparticles possessing a property of conductivity greater than before the mechanical sintering process is performed, wherein the mechanical sintering process is performed on the film without application of heat from an external source.
