Abstract
A scaling and patterning apparatus for producing thin films with multi-material, customized gradient patterns is disclosed. The apparatus includes a slot die body integrated with multiple inlets and corresponding converging channels passing materials through the die body into a geometry configured for mixing the materials internally. The scaling and patterning apparatus may be used in a method of preparing multi-material, gradient patterned thin film materials.
Claims28
An apparatus comprising:
- fluid inlets;
- a slot die outlet;
- and
- fluidically connected chambers;
- wherein:
- the fluidically connected chambers are arranged to define a flow path for fluids flowing in a fluid direction from the fluid inlets to the slot die outlet;
- the geometries of the flow path are configured to generate a heterogeneous film comprising a scalable gradient pattern of mixed fluids;
- the slot die outlet is configured to deposit the heterogeneous film onto substrate;
- and
- each chamber is selected from a group consisting of an entry chamber, a mixing chamber, and an exit chamber.

A method of thin film material deposition on a substrate comprising:
- feeding at least two fluids into a slot die via a plurality of fluid inlets;
- forming a fluid multi-material by interacting the at least two fluids in a plurality of mixing chambers within the slot die, the plurality of mixing chambers in fluidic communication with the plurality of fluid inlets such that the at least two fluids mix within the plurality of mixing chambers;
- and
- depositing the fluid multi-material onto the substrate via an outlet of the slot die in fluidic communication with the plurality of mixing chambers.
