Claim 0:
1. A method of fabricating high resolution patterns with engineered three-dimensional (3D) porous electroactive architecture from electroactive-material-based solutions comprising:
a. providing a solution of an electroactive material solute and a solvent for the electroactive material;
b. adding solid-phase particles to the solution to function as porogens to create a solution-phase ink;
c. patterning the solution-phase ink with the added solid-phase particles on a substrate;
d. removing at least substantially the electroactive material solvent from the patterned solution-phase ink to reduce the patterned solution-phase ink to a pattern of substantially the electroactive material impregnated with the solid-phase particles as hard templates, the pattern having a thickness and a surface;
e. exposing at least portions of at least some of the solid-phase particles at the surface of the pattern to expose the solid-phase particles in the pattern without substantially changing the porogen arrangement in the pattern, wherein the exposing comprises controlling power, scan rate, and spot size of a laser relative to the pattern in a manner effective to both (i) etch the pattern along the surface of the formed pattern and (ii) anneal the pattern to additionally produce the engineered 3D porous electroactive architecture with additional pores, voids, and/or edge plane defects;
f. removing at least some of the exposed solid-phase particles to leave the porogen pores where the removed solid-phase particles existed as hard templates prior to being removed to create an engineered 3D porous electroactive architecture in the pattern; and
g. functionalizing the engineered 3D porous electroactive architecture.
