Example Embodiment
[0042] The technical solutions in the embodiments of the present invention will be apparent from the drawings in the embodiment of the present invention.
[0043] The present invention provides a method of preparing a bionic superhydrophilic integrated chip, such as figure 1 As shown, including the following steps:
[0044](1) Place the polyamide film 2 on the PDMS substrate 3, using a laser engraving machine 1 to prepare laser induced graphene 4 on the surface of the polyamide film 2 to obtain an ultra-slim chip with a rose petal effect, name RPE (Rose) -pedaleffect superhydrophobic chip) 5;
[0045] (2) Coating organic solvent ethanol 8 on the portion of the laser-inducing graphene, obtaining a superhydrophobic chip having a lotus leaf effect, named LLE (LOTUS-LEAF Effect Superhydrophobic Chip) 6, the adhesive properties of the lotus leaf effect area are low Adhesive properties of rose petal effect region;
[0046] (3) By regulating the position and area of ethanol coating, se...
