Abstract

The invention provides a bioabsorbable conductive ink and its preparation method and sintering method, wherein the bioabsorbable conductive ink includes: at least two metal nanomaterials, the metal activity of the at least two metal nanomaterials is different, and the metal nanomaterials The material can realize the transient absorbability of the organism; the acid anhydride is used to generate a weak acid, and the weak acid reacts with the oxide layer on the surface of the metal nanomaterial to generate cations.

Description

technical field [0001] The present disclosure relates to the fields of transient bioabsorbable conductive materials and flexible electronics, and in particular, relates to a bioabsorbable conductive ink and its preparation method and sintering method. Background technique [0002] Transient electronic technology refers to an electronic device preparation technology in which substrate materials, inorganic semiconductor materials, interconnecting wires, and functional components of electronic devices can disappear completely or partially within the programming time at a specified rate, subverting the pursuit of electronic devices. Reliable and durable traditional mode, after exercising to complete the task, the electronic device completely dissolves and disappears through the pre-set trigger method. At present, the continuous progress of electronic technology has accelerated the replacement of electronic products, but also caused a huge amount of electronic waste. The applica...
