Flexible copper film using biodegradable binder and method of forming same

Abstract

Proposed are a copper film paste composition including copper particles, a biodegradable resin, a resin for structural reinforcement, a solvent, and an additive. In addition, a flexible copper film formed therefrom is proposed. The flexible copper film is capable of forming a uniform and smooth film, has significantly high bonding strength, and can minimize the environmental impact of waste disposal by using the biodegradable resin.

Dependencies are inferred from the claim text.
