Abstract
A method of dispensing a graded material includes generating droplets of a first working material, the droplets having a size in the range of 10 nanometers to 10 micrometers, adding the droplets of the first working material into a carrier fluid to create a first emulsion, wherein addition of the droplets of the first working material is controlled to create gradient in the emulsion, mixing the first emulsion to create a homogenous, graded mixture, and dispensing the homogenous, graded mixture onto a surface.
Claims9
A method of dispensing a graded material, comprising:
- generating droplets of a first working material;
- adding the droplets of the first working material into a carrier fluid to create a first emulsion, wherein addition of the droplets of the first working material is controlled to create a gradient in the emulsion;
- generating droplets of a second working material;
- adding the droplets of the second working material into a second carrier fluid to create second emulsion;
- mixing the first emulsion with the second emulsion to create a homogenous, graded mixture;
- separating the carrier fluid from the first and second working materials in the homogenous, graded mixture;
- and
- dispensing the homogenous, graded mixture onto a surface.
A method of dispensing a graded material, comprising:
- generating droplets of a first working material, the droplets having a size in the range of 10 nanometers to 10 micrometers;
- adding the droplets of the first working material into a carrier fluid containing a second working material to create an emulsion, wherein addition of the droplets of the first working material is controlled to create gradient in the emulsion;
- mixing the emulsion to create a homogenous, graded mixture;
- separating the carrier fluid out of the homogenous, graded mixture;
- and
- dispensing the homogenous, graded mixture onto a surface.
A method of dispensing a graded material, comprising:
- generating droplets of a first working material;
- providing a second working material in a carrier fluid in a common channel;
- injecting the first working material into the second working material in the carrier fluid in the common channel and controlling the injecting to control a ratio between the first working material and the second working material;
- and
- mixing the carrier fluid with the first working material and the second working material to create a homogenous, graded mixture;
- separating the carrier fluid out of the homogenous, graded mixture;
- and
- dispensing the homogenous, graded mixture onto a surface.
