Flexible electronic device containing electronic element and polymer nanosheet and method for manufacturing same

A flexible electronic device comprising:

• an electronic element;
• a first flexible polymer nanosheet and a second flexible polymer nanosheet each having a self-supportability, and each adhering to said electronic element, and each having a thickness of smaller than 1 μm, and each adhere to said electronic element through an intermolecular force and without an adhesive between said each polymer nanosheet and said electronic element and flexibly conform to an outer surface of said electronic element;
• and
• a conductive wiring formed on at least one of a surface of said first polymer nanosheet and a surface of said second polymer nanosheet, connected to an electrode of said electronic element through an intermolecular force between said conductive wiring and said electrode, and electrically connected to said electronic element,
• wherein said first polymer nanosheet and said second polymer nanosheet are in a close contact with and stick to each other without an adhesive through an intermolecular force between said first polymer nanosheet and said second polymer nanosheet, and said electronic element is sandwiched between said first polymer nanosheet and said second polymer nanosheet.

A method for manufacturing a flexible electronic device, comprising:

• a step of forming a first polymer nanosheet having a self-supportability on a substrate;
• a step of forming a conductive wiring on a surface of said first polymer nanosheet;
• a step of arranging an electronic element in a manner such that an electrode of said electronic element is capable of coming into contact with said conductive wiring;
• a step of bringing a second polymer nanosheet having a self-supportability into a close contact with said first polymer nanosheet to stick said second polymer nanosheet to said first polymer nanosheet through an intermolecular force with said electronic element and said conductive wiring being sandwiched therebetween, and thus electrically connecting said electronic element and said conductive wiring;
• and
• a step of separating said substrate from said first polymer nanosheet.
