Abstract

A method for manufacturing a patterned polyimide aerogel film on a substrate includes: dispensing a polyimide prepolymer sol onto a first portion of a surface of a substrate, a second portion of the surface of the substrate being substantially free of the polyimide prepolymer sol; forming a patterned film of a polyimide prepolymer gel on the substrate from the polyimide prepolymer sol; drying the polyimide prepolymer gel to form a patterned film of a polyimide prepolymer aerogel on the substrate; and curing the polyimide prepolymer aerogel on the substrate to form the patterned polyimide aerogel film on the first portion of the surface of the substrate, the second portion of the surface of the substrate being substantially free of the patterned polyimide aerogel film.
