Table 3.
Tensile strength of chitosan (CHIT), chitosan-polydopamine (CHIT-PDA) and chitosan-polydopamine-xanthan gum (CHIT-PDA-XG) formulations on textile and carboard. The analysis was performed according to UNI EN 1465 for the determination of tensile lap-shear strength bonded. * Tensile strength is determined by the ratio of the maximum force (Fmax) to the cross-section area (Section).
| Section (mm2) | Fmax (N) | Tensile Strength * (N/mm2) | ||
|---|---|---|---|---|
| Cardboard | CHIT | 1680 | 501.9 | 0.298 |
| CHIT-PDA | 1710 | 390.4 | 0.228 | |
| CHIT-PDA-XG | 3150 | 999.2 | n.d. | |
| Textile | CHIT | 1800 | 431.9 | 0.240 |
| CHIT-PDA | 1800 | 356.6 | 0.198 | |
| CHIT-PDA/XG | 3501 | 665.1 | n.d. |
