Then deionized water (0.54 mL), ethanol (0.80 mL), and HCl (0.01 mL) were added under rapid stirring at ambient temperature for ca. 10 min. The clear solution was then cast into a plastic Petri dish and covered with a Parafilm. Based on a preliminary series of gelation experiments it was shown that after a few days depending on the PCL end-groups (hydroxyl or triethoxysilane) the Parafilm was to be removed. The gelified material was then dried under ambient condition for 1 week and finally cured at 100 °C for 2 days prior to testing.
