Abstract
Poli(vinil-alkohol) (PVA) i hitozan kompatibilni su polimeri koji se mogu miješati. Biokompatibilnost ovih polimera omogućuje čestu upotrebu njihovih mješavina u medicinskom i biološkom području. PVA je topiv u vodi, što je problem za ovakve primjene. Mješavine PVA i hitozana mogu se umrežiti glutaraldehidom čime se može spriječiti topivost. Za potrebe eksperimentalnog dijela rada pripremljena su ispitna tijela od čistog PVA i mješavina PVA i 5, 20 i 35% hitozana umreženih s 1%-tnom vodenom otopinom glutaraldehida. Napravljena je analiza umreženosti metodom uranjanja u vodu u trajanju od 24h pri čemu se mjerila promjena mase ispitnih tijela. Pomoću računalne tomografije analizirana je promjena volumena ispitnog tijela od čistog PVA s ciljem provjere pogodnosti ove metode za analizu stupnja umreženosti.
Abstract (english)
Poly(vinyl-alcohol) (PVA) and chitosan are compatible polymers that can be mixed. Mixtures of these polymers are frequently used in medicine and biological applications due to their biocompatibility. PVA is soluble in water that is inappropriate for these applications. PVA and chitosan mixtures can be crosslinked with glutaraldehyde. For the experimental part of this work, pure PVA, PVA and 5%, 20% and 35% chitosan mixtures were prepared and crosslinked with 1% GA aqueous solution. Crosslinking analysis was made by means of water immersion test in duration of 24h where mass change of test specimens was measured. Volume change of pure PVA test specimen was analysed using computed tomography in order to verify the suitability of this method for crosslinking degree analysis.
