2 Vlasta ŠtěpánováPASNPG, Blansko Outline Introduction Experimental set-up Using methods of surface analysis Results Conclusion

3 Vlasta ŠtěpánováPASNPG, Blansko Experimental set-up DCSBD (Diffuse Coplanar Surface Barrier Discharge)

4 Vlasta ŠtěpánováPASNPG, Blansko Experimental set-up in ambient air at atmospheric pressure size of plasma 0,2 – 0,3 mm power 300 W electrode dimensions 8,5 x 21 cm

5 Vlasta ŠtěpánováPASNPG, Blansko Experimental set-up

6 Vlasta ŠtěpánováPASNPG, Blansko Experimental set-up

7 Vlasta ŠtěpánováPASNPG, Blansko Using methods of surface analysis Atomic force microscop (AFM) LDI-TOF MS Contact angle measurement

8 Vlasta ŠtěpánováPASNPG, Blansko Using methods of surface analysis Atomic force microscop (AFM) change of surface roughness depending on the time of plasma treatment parametres (RMS and Ra)

9 Vlasta ŠtěpánováPASNPG, Blansko Using methods of surface analysis LDI-TOF MS Laser Desorption Ionisation Time-Of-Flight Mass Spectrometry

10 Vlasta ŠtěpánováPASNPG, Blansko Using methods of surface analysis Contact angle measurement device See System (Surface energy evaluation system) change the size of the contact angle depending on the time of surface treatment

11 Vlasta ŠtěpánováPASNPG, Blansko Results AFM Time of plasma treatment [s] RMS [nm]R a [nm] 00,490,38 10,890,64 51,250,96 101,250,96 251,270,94 607,303, ,008,80

12 Vlasta ŠtěpánováPASNPG, Blansko Results AFM

13 Vlasta ŠtěpánováPASNPG, Blansko Results 3D model time of plasma treatment 10 s

14 Vlasta ŠtěpánováPASNPG, Blansko Results LDI-TOF MS plasma treated x untreated glass chemical x plasma cleaning adsorption of nanogold

15 Vlasta ŠtěpánováPASNPG, Blansko Results

16 Vlasta ŠtěpánováPASNPG, Blansko Results Contact angle measurement volume of drop 4  l deionized water Change of contact angle: before treatment 37° after treatment 14°

17 Vlasta ŠtěpánováPASNPG, Blansko Results Adsorption of nanogold

18 Vlasta ŠtěpánováPASNPG, Blansko Results Adsorption of nanogold

19 Vlasta ŠtěpánováPASNPG, Blansko Conclusion Plasma treatment improves hydrophilic properties of glass surface Cleaning glass with plasma treatment is more efficient than chemical cleaning Plasma treatment improves adsorption of gold nanoparticles on a glass surface

20 Vlasta ŠtěpánováPASNPG, Blansko Thank you for your attention.
