Layer-by-layer techniques incorporating upcycled TPEE: from waste to conductive, multi-responsive, self-healable, and highly-stretchable electronics

Upcycled thermoplastic polyester elastomers, poly(ionic liquid- co -acrylic acid), and MXene nanosheets are utilized to fabricate conductive, stretchable, self-healable, and alkaline-responsive multilayered films.
