Research Applications

  • Fluorinated polymers are widely used as biomaterials in various biomedical implants and device applications. However, the risk of thrombosis, surface-induced inflammation, and microbial infection are still key issues that limit its use. Studies have shown that PVDF tubing as a matrix, through solvent swelling method, a new fluorinated NO donor S-nitroso-N-pentafluoropropionyl-penicillamine (C2F5 -SNAP) can be combined to In the PVDF tubing, nitric oxide (NO) can be released. This new NO-releasing fluorinated polymer may have the potential to improve the biocompatibility and antibacterial activity of various biomedical devices.

  • PVDF micropillars can be used to prepare micropillar arrays for acoustic sensors. The research results show that PVDF sensors based on micro-pillar arrays and patterned electrodes have higher sensitivity than commercial PVDF thin-film sensors and all-electrode micro-pillar arrays, while exhibiting the same wide frequency bandwidth. Constrained optimization algorithms have been developed as a function of the geometrical and electrical parameters of the sensor and conditioning amplifier. The simulation results provide guidance for micro-manufacturing and amplifier selection.
