XPS and IR studies of plasma polymers layer deposited from allylamine with addition of ammonia

摘要

The plasma polymerization of allylamine was often investigated to modify polymer surfaces with primary amino groups. However, this deposition process is characterized by a significant loss of NH2 groups originally present in allylamine. To compensate this loss of NH2 groups in the deposited plasma polymer layer ammonia was added to the plasma process. Indeed, huge amount of nitrogen could be incorporated into the plasma polymer using addition of ammonia but the yield in primary amino groups was not increased. Extensive side-reactions were observed.
