在常压下，利用N-2、N-2 + H-2和N-2 + NH3混合物中介质阻挡放电的余辉，LDPE表面可以被伯胺基功能化。通过最近开发的ATR FT-IR光谱方法进行定量分析，可以计算每单位面积产生的NH2基团的数量，发现在N-2 + H-2处理后，就所获得的伯胺的面积密度而言（超过15 nm(-2)）是最有效的，但在纯N-2中也可以获得相当数量的-NH2，高达约3 nm（-2）。讨论了氨化反应的可能机理和气体添加剂的作用。
Surfaces of LDPE can be functionalized with primary amino groups using the afterglows from dielectric barrier discharges in N-2, N-2 + H-2, and N-2 + NH3 mixtures at atmospheric pressure. Quantitative analysis by a recently developed ATR FT-IR spectroscopic method allows calculation of the number of NH2 groups generated per unit area Treatment in N-2 + H-2 afteralows was found to be most efficient in terms of area densities of primary amines achieved (more than 15 nm(-2)), but appreciable quantities of -NH2, up to about 3 nm(-2), are also obtained in pure N-2. Possible mechanisms of the amination reaction and the roles of gas additives are discussed.
