氮等离子体处理的表面与芳族醛（例如原型4-三氟甲基-苯甲醛（TFBA））的化学衍生化反应长期以来被认为对伯胺具有选择性。使用FTIR-ATR光谱的原位研究的结果挑战了这一假设的有效性：在氮-氢混合物中的介电阻挡放电的余辉与随后的氢/氘交换或TFBA衍生化的聚乙烯表面的改性表明，后者不遵循通常假设的反应方案。
Chemical derivatization reactions of nitrogen plasma-treated surfaces with aromatic aldehydes, such as the prototypic 4-trifluoromethyl-benzaldehyde (TFBA), have for a long time been considered selective for primary amines. Results of an in situ study using FTIR-ATR spectroscopy challenge the validity of this assumption: Modification of polyethylene surfaces by afterglows of dielectric barrier discharges in nitrogen–hydrogen mixtures with subsequent hydrogen/deuterium exchange or TFBA derivatization suggests that the latter does not follow the commonly assumed reaction scheme.
