▎ 摘　　要

NOVELTY - Preparing three-dimensional (3D) printed electrode materials for biological microfluidic chip comprises (i) preparing graphene oxide gel and dissolving graphene oxide in a solvent to obtain graphene oxide gel, and (ii) preparing 3D printing electrode materials comprising (iia) adding oligomer, active monomer, degradation agent, conductive particle, antifoaming agent, polymerization inhibitor, dispersant and sintering auxiliary agent to the graphene oxide gel, ball milling and uniformly mixing, and (iib) vacuumizing and stirring the mixture after ball milling to eliminate air bubbles, then adding photoinitiator and dispersing uniformly to obtain the finished product. USE - The method is useful for preparing 3D printed electrode materials for biological microfluidic chip. ADVANTAGE - The method: disperses graphene oxide in the photosensitive resin in a better manner; realizes high utilization rate of graphene oxide, so that the prepared biological microfluidic chip 3D printing electrode material has a lower viscosity; is more suitable for light curing 3D printing; improves the conductivity, so that the prepared 3D printed electrode material for the biological microfluidic chip obtains better conductivity; and does not damage the surface structure of the prepared 3D printed electrode. The 3D printed electrode: has a complete shape, no collapse defect, and excellent electrical conductivity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a biological microfluidic chip 3D printing electrode material prepared by the above mentioned method; (2) preparing 3D printed electrodes by printing using the 3D printed electrode material of biological microfluidic chip; and (3) a 3D printing electrode.
