Abstract:
A flexible conductive paste and a flexible electronic device are provided, which relate to the technical field of new materials. The flexible conductive paste includes: 3% to 7% by weight of a film former; 20% to 50% by weight of a conductive powder; 25% to 45% by weight of a liquid metal microcapsule; 10% to 30% by weight of a solvent; 0.1% to 5% by weight of a curing agent; and 0.5% to 5% by weight of a functional additive. The wall of the liquid metal microcapsule is a coating resin, the core of the liquid metal microcapsule is a liquid metal. The melting point Tm of the liquid metal satisfies Tm≤T1. The film former has a molecular weight within a range of 15000 to 30000, and has a glass transition temperature Tg smaller than or equal to T1. T1 is a temperature at which the flexible conductive circuit manufactured by the flexible conductive paste is deformed. The flexible conductive circuit of the present disclosure can have better conductivity and better flexibility simultaneously.
