▎ 摘　　要

NOVELTY - Hydrophilic-hydrophobic patterned substrate circulation microchannel reactor comprises a first area and a microchannel area arranged side by side, and the first area connected with the microchannel area, the first region includes a first hydrophilic region and a hydrophobic region (12) arranged at intervals in sequence, along the direction of liquid flow, the size of the first hydrophilic region gradually becomes smaller, the microchannel area includes microwalls and fluid channel areas arranged at intervals in sequence, and the first hydrophilic area (11) and the hydrophobic area are all connected to the fluid channel area; the surface of the fluid channel area is also provided with a nano-catalyst layer and / or biological enzymes; when the liquid circulates between the first area and the microchannel area, it is in a circular flow. USE - Used as hydrophilic-hydrophobic patterned substrate circulation microchannel reactor. ADVANTAGE - The reactor is simple and fast, it is flexible and easy to use, it is suitable for multiple catalytic reaction and multiple shape reaction kettle, it is convenient for mass production, has strong application value in the safe chemical industry, green chemical industry and high-efficiency chemical industry. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing microchannel reactor comprising (1) preparing a substrate containing hydrophilic and hydrophobic patterning, the substrate containing hydrophilic and hydrophobic patterning includes the bottom surface of the microchannel region, and the first hydrophilic region and the hydrophobic region containing the above-mentioned structure, (2) preparing microwall on the bottom surface of microchannel district described in step (1), make microchannel district be provided with microwall and fluid passage district at intervals successively, preparing nano-catalyst on the surface of described fluid passage district layer and/or biological enzymes to prepare a microchannel reactor. DESCRIPTION OF DRAWING(S) - The drawing shows a top view of the reactor of a hydrophilic and hydrophobic patterned substrate circulating micro-channel reactor. 2Micro-channel region 3Second area 11First hydrophilic area 12Hydrophobic region 22Fluid channel region
