AB  - Indwelling medical catheters are frequently utilized in medical procedures, but 
      they are highly susceptible to infection, posing a vital challenge for both 
      health workers and patients. In this study, the superhydrophobic 
      micro-nanostructure surface was constructed on the surface of thermoplastic 
      polyurethane (TPU) membrane using heavy calcium carbonate (CaCO(3)) template. To 
      decrease the surface free energy, hydroxyl silicone oil was grafted onto the 
      surface, forming a super-hydrophobic surface. The water contact angle (WCA) 
      increased from 91.1 degrees  to 143 +/- 3 degrees  when the concentration of heavy calcium CaCO(3) 
      was 20% (weight-to-volume (w/v)). However, the increased WCA was unstable and 
      tended to decrease over time. After grafting hydroxyl silicone oil, the WCA rose 
      to 152.05 +/- 1.62 degrees  and remained consistently high for a period of 30 min. 
      Attenuated total reflection infrared spectroscopy (ATR-FTIR) analysis revealed a 
      chemical crosslinking between silicone oil and the surface of TPU. Furthermore, 
      Scanning electron microscope (SEM) image showed the presence of numerous 
      nanoparticles on the micro surface. Atomic force microscope (AFM) testing 
      indicated a significant improvement in surface roughness. This method of creating 
      a hydrophobic surface demonstrated several advantages, including resistance to 
      cell, bacterial, protein, and platelet adhesion and good biosecurity. Therefore, 
      it holds promising potential for application in the development of TPU-based 
      medical catheters with antibacterial properties.
