Manufacturing of bionic functional surface based on the replication of biological surface morphology

Direct replication of biological surface morphology to form bionic functional surface with high precision in morphology and approximation in function is a new attempt on the manufacturing of bionic functional surface directly using natural creatures. The bio-replicated forming was proposed. Taking shark skin as representative of the non-smooth biological surface, and the micro-embossing as the structure transfer method, the large-area replication of the outward morphology on shark skins was demonstrated. Experimental results on replication precision and resistance test in water tunnel indicates that the bio-replicated forming shows good fidelity both in morphology and function, in the direct replication of the low-resistance biological surface morphology.
