| Description
| - Dostupnost volného prostoru v krystalech zeolitu typu MFI byla studována pomocí metody jodového indikátoru spojené s optickou mikroskopií. Tato metoda byla použita k odhadu adheze mezi polyimidovou matricí a zeolitovou fází, sodtupnosti kanálů zeolitu pro molekuly plynu a také prostorové distribuce krystalů zabudovaných v kompozitech. V syntetizovaných kompozitech, v nichž je většina krystalů překryta vrstvou polyimidu, je kanálový systém zeolitické fáze zaplněn tozpouštědlem používaným při syntéze. V neupravených kompozitech je tedy zeolitická záze pro jod nedostupná. Účinnost metod odstraňování polyimidové vrstvy překrývající povrch krystalů byla charakterizována pomocí probarvovacích vzorů a kinetiky probarvování. Stejné techniky bylo použito i k charakterizaci účinnosti operací použitých k desorpci rozpouštědel (N-methyl-2-pyrrolidon, N,N´-dimethylformamid, n-heptan) z kanálového systímu silikalitu-1. (cs)
- The accessibility of void space in MFI-type zeolite crystals, isolated and embedded in a polyimide (PI) matrix, was studied using optical microscopy coupled with an iodine indicator technique (IIT). IIT was used to estimate the adhesion between the PI matrix and the zeolitic phase, the accessibility of the zeolite void space for gas molecules as well as for characterizing the spatial distribution of embedded crystals in the composite. The channel system of the zeolitic phase in as-synthesized composities with the majority of crystals covered by a layer of PI is occupied by the solvent molecules used in composite synthesis. In untreated composites, the zeolitic phase is inaccessible to iodine sorption. Colouring patterns and colouring kinetics have been used to characterize the efficiency of the treatment for removing the PI covering layer from the crystal surface.
