AB  - Shark skin surfaces show non-smoothness characteristics due to the presence of a 
      riblet structure. In this study, biomimetic shark skin was prepared by using the 
      polydimethylsiloxane (PDMS)-embedded elastomeric stamping (PEES) method. Scanning 
      electron microscopy (SEM) was used to examine the surface microstructure and fine 
      structure of shark skin and biomimetic shark skin. To analyse the hydrophobic 
      mechanism of the shark skin surface microstructure, the effect of biomimetic 
      shark skin surface microstructure on surface wettability was evaluated by 
      recording water contact angle. Additionally, protein adhesion experiments and 
      anti-algae adhesion performance testing experiments were used to investigate and 
      evaluate the anti-biofouling properties of the surface microstructure of 
      biomimetic shark skin. The recorded values of the water contact angle of 
      differently microstructured surfaces revealed that specific microstructures have 
      certain effects on surface wettability. The anti-biofouling properties of the 
      biomimetic shark skin surface with microstructures were superior to a smooth 
      surface using the same polymers as substrates. Moreover, the air layer fixed on 
      the surface of the biomimetic shark skin was found to play a key role in their 
      antibiont adhesion property. An experiment into drag reduction was also 
      conducted. Based on the experimental results, the microstructured surface of the 
      prepared biomimetic shark skin played a significant role in reducing drag. The 
      maximum of drag reduction rate is 12.5%, which is higher than the corresponding 
      maximum drag reduction rate of membrane material with a smooth surface.
