▎ 摘　　要

NOVELTY - A photothermal adhesive composition comprises graphene-transition metal compound composite. USE - A photothermal adhesive composition for fabrication of a microfluidic chip (claimed). ADVANTAGE - By using the photothermal adhesive composition containing the composite, microfluidic chips that pass fluids through with neither leakage nor deformation can be effectively fabricated. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) manufacture of photothermal adhesive composition which involves reacting graphene with a hydrophilic polymer and then reducing the graphene, and mixing the graphene with transition metal compound nanoparticles to form a composite; and (2) fabrication of a microfluidic chip which involves loading the photothermal adhesive composition to a target site on a microfluidic chip lower substrate, irradiating a laser to the target site, and contacting a microfluidic chip upper substrate with the target site on the lower substrate, followed by irradiating a laser on it.
