Surface Analysis of PP Treated by Plasma - X-ray Phtoelectron Spectroscopy(XPS) -

印刷する

Summary

XPS is the highly sensitive method for the analysis of functional groups on the outmost surface of a few nm area. It is useful to analyze functional groups generated by a surface treatment like Plasma treatment.

XPS analysis of the surface of PP treated by Plasma

Fig.1 O,N content on the surface of PP treated by Plasma

It was found that contents of O and N increased with the lapse of time of Plasma treatment.

Fig.2 The spectra of XPS-C1s after plasma treatment and the peak separation (after the treatment for 120sec. )

The peak separation of C1s indicated that functional groups such as C-OH(C-O-C) C=O COOH(COO) were generated with the lapse of time of Plasma treatment
