Characterisation of PMMA/ATH Layers Realised by Means of Atmospheric Pressure Plasma Powder Deposition

Table 3

Binding energies (BE) of relevant peaks, particular concentration , and measured relative area of carbon bonds within the C1s peak as well as literature values for of the untreated powder before deposition.

Peak	BE in eV	in at.%	in %	in % [32]
O1s	532.0	37.6
Al2p	74.4	7.2
C1s
–CH2, –CH3	284.7	22.7	41.2 ( MPA^1)	42.0 ( MPA)
C–C4	285.5	11.4	20.6 (= 0.5 · MPA)	21.0 (= 0.5 · MPA)
–O–CH3	286.5	11.9	21.5 (= 0.5 · MPA)	21.0 (= 0.5 · MPA)
O–C=O	288.8	9.3	16.8 (= 0.4 · MPA)	17.0 (= 0.4 · MPA)

MPA = main peak area.
