This invention discloses a method for rapidly preparing metal microelectrodes using vacuum filling and mechanical exfoliation, relating to the field of micro-nano manufacturing. This method significantly reduces the viscosity of the liquid metal and its flow resistance by preheating the PDMS-hydrosol bonding interface at high temperature. Simultaneously, preheating intensifies the thermal motion of gas molecules within the microchannel, facilitating rapid gas expulsion. This allows for complete filling of the microchannel within a short vacuum holding time (at least 1 minute), significantly shortening the vacuum holding time compared to the traditional 20-30 minute process, thus greatly improving preparation efficiency.

This invention relates to a rare-earth complex ink incorporating a pyrazole boron Ce(III) complex with a thermally conductive material, its preparation, and its application, belonging to the field of light-emitting displays. More specifically, by incorporating a thermally conductive material into the ink, heat can be effectively and rapidly conducted away, preventing non-radiative losses due to overheating of the rare-earth complex and thus improving luminous efficiency. During inkjet printing, an increase in printhead temperature may cause rare-earth complex particles in the ink to agglomerate, thereby affecting print uniformity and pattern quality. The addition of a thermally conductive material helps stabilize the ink temperature, reduces particle thermal movement, prevents agglomeration and sedimentation, improves printing stability and reliability, and ensures long-term printhead operation.
