Investigation of dialdehyde cellulose crosslinked poly(vinyl)alcohol hydrogels

Popis výsledku v původním jazyce

Dialdehyde cellulose (DAC) derived from α-cellulose by periodate oxidation was utilized as a crosslinking agent for poly(vinyl alcohol) (PVA) to prepare PVA/DAC hydrogels. Two catalyst systems based on diluted hydrochloric or sulfuric acid and the role of DAC solution age (1, 14 and 28 days old) on material properties of formed PVA/DAC samples were studied by solid-state CP-MAS 13C NMR, XRD analysis and in the terms of network parameters and mechanical properties. The crosslinking potential of DAC was investigated on broad concentration range and found to be considerably better than that of common crosslinking agent glutaraldehyde. The properties of PVA/DAC hydrogels are governed by the number average molecular weight (
