▎ 摘　　要

NOVELTY - Flexible printed article comprises a non-conductive, graphene oxide membrane base substrate, and an electronic component positioned on the non-conductive, graphene oxide membrane base substrate. USE - The flexible printed article is used in a wearable device (claimed) such as trace or track, a conductive contact pad, transistors, diodes, capacitors, memristors, energy storage devices such as supercap, batteries, radio-frequency identification devices, light-emitting devices, and sensors (e.g. strain, chemical or photo). ADVANTAGE - The flexible printed article exhibits excellent durability and resilience, and exhibits a normalized resistance that remains within 10% of an initial normalized resistance over 30000 bending cycles. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a printing method, comprising inkjet printing a water-based ink directly on a non-conductive graphene oxide membrane base substrate to form a flexible printed article; and (2) a three-dimensional (3D) printing method, comprising forming a base structure by iteratively, applying layers of a polymeric build material, patterning at least a portion of each layer with a fusing agent, and exposing each layer to electromagnetic radiation, and coalescing at least a portion of each layer, applying a graphene oxide membrane on the base structure, and depositing a water-based, conductive ink on at least a portion of the graphene oxide membrane, and forming a printed electronic component.
