Modified substrate and methods for manufacturing the same

A method for manufacturing a modified substrate, comprising:

• providing a substrate selected from the group consisting of a glass substrate, a glass ceramic substrate, and a silicon substrate;
• applying a polyimide precursor on at least one surface of the substrate, wherein the polyimide layer comprises (i) a diamine residue selected from a nitrogen-containing heteroaromatic ring containing at least two nitrogen atoms, an aromatic ring or heterocyclic ring containing at least two —COOH groups, and a combination thereof, and (ii) a
• group;
• wherein
• each of R1 and R2 is independently C1-C4 alkyl,
• each of R3, R4, R5, and R6 is independently H, C1-C4 alkyl, or phenyl, and
• m is an integer greater than 0;
• and
• heating at a temperature between about 150° C. and 350° C. to cure the polyimide precursor into a polyimide layer.
