New method links graphene nanolayers for tougher, elastic films

https://phys.org/news/2024-06-method-links-graphene-nanolayers-tougher.html

"conductive honeycombed carbon atom layered array... cross-linked (but not chemically, uses rotaxanes) graphene nanolayers with mechanically spatially entangled interlocked molecules... rotaxanes' axle uses charged group (ammonium) holding wheel in specific position... OH group attached to axle/ wheel by linker... stretchable to 20%/ bent repeatedly without damage, also retaining high electric conductivity... bendable electronics, batteries, aeronautic/ space flight composite materials"
