Article Synopsis
- Ionogels were created by mixing Aerosil A380 with varying amounts (16.3 to 79.9 mol %) of a specific ionic liquid, 1-methyl-3-octyl-imidazolium tetrafluoroborate (OMIM BF).
- Evidence of changes in the ionic liquid's behavior was observed through NMR and IR spectroscopy, indicating that the liquid was confined within the silica structure, which also affected its decomposition temperature.
- Structural analysis revealed that the ionic liquid filled different pore sizes in the Aerosil, with notable increases in size correlations in higher IL content; this suggests that altering IL concentrations can modulate the material's properties effectively.
A series of multiblock polyurethane-ureas (PUU) based on polycaprolactone diol (PCL) with a molecular mass of 530 or 2000 g/mol, as well as hard segments of different lengths and structures, were synthesized by the step-growth polymerization method. The chemical structure of the synthesized multiblock copolymers was confirmed by IR- and NMR-spectroscopy. Differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA) were used to determine the relaxation and phase transition temperatures for the entire series of the obtained PUU.
