XPS of chemically modified low‐density polyethylene surfaces: observations on curve‐fitting the C 1s spectrum

摘要: The curve-fitting of the complex C 1s envelopes (obtained under high-energy-resolution XPS conditions) resulting from surface chemical modification low-density polyethylene has been investigated. main problem is modelling dominant, asymmetric component due to unmodified hydrocarbon. Two approaches have compared, namely use a full (four-component) vibrational progression or single peak with lineshape recently introduced by Gelius. As well as goodness fit criteria, agreement between measured O intensity and that predicted intensities high-binding-energy components (from oxygen-containing functional groups) was used in assessment. Under relatively low-level, but practically relevant, conditions studied, two are equally effective. However, they can give rise significant differences relative components. Broadening various function treatment also studied. Copyright © 2002 John Wiley & Sons, Ltd.
