Secondly, the pulse discharge plasma with allylamine was discussed, and the modification results with two kinds of discharge models were compared. The results showed that discharge models had influences on the plasma treatment results, especially under lower pressure and higher temperature with pulse discharge. The nitrogen element content in the layer under the pulse discharge was obviously lower than that under the continuous discharge, but there was higher proportion NH〓 groups remaining in the layer under the pulse discharge. The sample surfaces obtained by pulse discharge also had good biocompatibility.
