  • Formation of polysaccharide aerogels in ethanol [Elektronski vir]
    Horvat, Gabrijela, kemija ; Knez, Željko ; Novak, Zoran
    Aerogels are outstanding materials, obtained by the sol-gel process. The production of polysaccharide aerogels is however time-consuming and their use for life-science applications is limited. To ... accelerate the production time, ethanol was used to induce the gelation of pectin, alginate, xanthan and guar gum. Polysaccharide aerogels were produced by dissolution in water, gelation in ethanol and supercritical drying. Only ethanol was used for the gelation without the use of any other cross-linking agent. In addition there was no solvent-exchange step prior to supercritical drying since the gelation occurred directly in ethanol. Differential scanning calorimetry was used to analyze the decompositions of the samples and also to measure their thermal conductivities. SEM and rheological analyses were performed in order to characterize the new materials.
