AbstractPlastic films are among the most used materials. In many applications, both high strength and low thickness are required. The thickness of free-standing plastic films has recently been reduced to micrometres, 200 nm and even 60 nm. Pushing this boundary further faces considerable challenges, as processability conflicts with stability at the ‘ultrathin’ scale (below ~100–200 nm).
