Embodiment 1
[0058] (1) Mix the PDMS pre-polymerization solution and the initiator Dow Corning 184 at a mass ratio of 10:1, discharge the air bubbles, pour it into an empty groove of 10cm*6cm*1cm, put it in an oven, and cure it at 80°C for 4 hours to obtain PDMS flakes;
[0059] (2) with CO 2 A type laser punches holes on the PDMS sheet obtained in step (1), the laser power is set to 80%, and repeats twice; the diameter of a single laser spot is set to 0.3 millimeters, and the distance between the laser spots is 0.6 millimeters, which are staggered along the long axis Cloth, long axis 80 millimeters, short axis 19 millimeters arrayed tapered hole matrix; made polydimethylsiloxane template with arrayed tapered holes;
[0060] (3) Preparation of epoxy resin glue: select commercially available epoxy resin glue, for example, Kangda New Material Company, including A and B two tubes, A tube is epoxy resin, B tube is curing agent; A tube, B tube Mix the glue evenly with a mass ratio of 1:1.
