| Abstract: | Addition of 1,2-O-(ethane-1,2-diyl)-α-d-glucofuranose, which is originally a poor organogelator, can support the gelating abilities of good glucofuranose-based organogelators. The properties of such two-component gels can be tuned by changing the proportion of the saccharides. The saccharide's ability to form two-component gels can be explained on the basis of its crystal structure, particularly, the way in which sugar molecules stack (or not) into hydrogen bond-based chains and the architecture of these chains. The thermal stability of the obtained two-component gels was characterised by measuring its T gel temperature. SEM and XRD techniques were used to characterise the xerogels. Addition of poor gelator increases the thermal stability of the gel formed by good gelator | |
