High surface functional groups concentration, excellent dynamical stability and mechanical properties are ideal for biomedical plasma polymers. Herein, we report a simple and effective approach to fabricating such an ideal plasma polymeric allylamine film on 316L stainless steel (SS) by pulsed plasma polymerization. The experimental results show that the concentration of the primary amine groups (NH 2 /C) of the plasma polymeric allylamine film was 2.4 ± 0.4%. The plasma polymeric allylamine film possesses not only high surface NH 2 concentration, but also high cross‐linking degree and close‐knit network structure that could well resist hydrolysis, and dissolution in the aqueous solution. Furthermore, the plasma polymeric allylamine film was used as a stent coating that shows a good resistance to the deformation behaviour of compression and expansion of the stent.
