Table 2.
Comparative presentation of roughness parameters (Ra, Rq, and Rz) of dye-doped PMMA polymer surfaces before and after argon glow discharge plasma treatment for 300 s.
| Samples | Roughness parameters | ||
|---|---|---|---|
| Ra | Rq | Rz | |
| Untreated DR1 dye-doped polyamide 6 | 5.436 nm | 6.707 nm | 29.353 nm |
| Plasma-treated DR1 dye-doped polyamide 6 | 16.412 nm | 19.502 nm | 64.654 nm |
The roughness parameters include the arithmetic averages of the assessed values (Ra), the root mean square average of height deviations from the mean line (Rq), and the maximum peak to valley height (Rz).
