【 摘 要 】

The mussel-inspired polydopamine (PDA) coating, which is unstable and fragile on poly(tetrafluoroethylene) (PTFE) surface, is now successfully stabilized by using argon plasma treatment as a pre-treatment before conducting PDA coating. In this study, the parameters of plasma including plasma energies, gas pressures and treating time were adjusted to construct a stable PDA coating layer on PTFE surface. Fourier-transform infrared spectroscopy and X-ray photoelectron spectroscopy were used to characterize the surfaces. The sonication stability of PDA coating layer on plasma treated PTFE surface was evaluated. The robust PDA coating layer reported in this study can act as a reactive platform for further modification and reaction on PTFE.
