A preparation method of a bionic adhesive material with a tip-expanded microstructural array includes the following steps: machining through-holes on a metal sheet; modifying morphology of a through-hole by electroplating, using the metal sheet in step 1 as an electroplating cathode, and arranging the electroplating cathode and an electroplating anode in parallel to prepare a hyperboloid-like through-hole array assembly, fitting a lower surface of the hyperboloid-like through-hole array assembly tightly to an upper surface of a substrate assembly to prepare a through-hole assembly of a mold; and filling the mold assembly with a polymer, curing, and demolding to obtain the adhesive material with the tip-expanded microstructural array.
