A method for preparing metal microelectrode by rapid vacuum filling and mechanical peeling

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.
