Laser-induced graphene: hitting Kapton tape with a laser makes a conductive, high-surface-area material
johnowhitaker · x · 2026-09-27
johnowhitaker shares a TIL: hitting polyamide tape/film (e.g., Kapton tape) with a laser produces "laser-induced graphene" — a somewhat conductive, high-surface-area material.
- Potential applications in catalysis, especially with added dopants
- Running current through it enables self-heating
A surprisingly accessible DIY materials trick with real research potential.
