| Popis: | The surfaces of PVA fibers prepared by in situ fibrillation were modified by first crosslinking using glyoxal and then attaching cationic and anionic groups by grafting. Crosslinking prior to modification was beneficial in minimizing the solubility of the fibers in the aqueous medium in which they were modified. Heterogeneous modification techniques were employed so that fiber properties could be preserved. PAA and PDMC were grafted from the PVA microfibrils using the KPS/NaS 2 O 3 redox initiating system. Grafting was confirmed by FTIR and NMR spectroscopy. The modified PVA fibers were also analyzed by DSC, TGA, and SEM. |
