dc.description.abstractThis research aims to characterize newly synthesized pure high gelatin content aerogels and the crosslinked version of the gelatin aerogels with glutaraldehyde (GTA). The cross-linking process was achieved by the interaction of the gelatin gel with the crosslinker (GTA) and using a subsequent supercritical CO2 drying process. Three different aerogels with the following composition will be studied: 30 wt.% gelatin/water (RM01); 20 wt.% gelatin/water (RM04); and 20 wt.% gelatin/water crosslinked with 2.5 wt. % GTA (RM06). In this research, the focus is the characterization of newly synthesized advanced materials by conventional characterization techniques (SEM, N2-porosimetry, IR) as well as compressive strength tests. The SEM pictures illustrate the dense fibrils-like structure of the pure gelatin samples and the altered one of the GTA-gelatin crosslinked, impacting the strength of the two types of aerogels. Moreover, with increasing gelatin content we can observe a trend in increasing the mechanical properties which give these materials the ability to withstand high stress.
