Stimuli-Responsive Hydrogels Based on Polyglycerol Crosslinked with Citric and Fatty Acids
Table 2
Samples compositions used for the hydrogels synthesis.
| Hydrogel | Molar ratios of OH groups of polyglycerol (PG) : COOH groups of crosslinking agents (CG) | Molar compositions of COOH groups of citric acid (CA) and fatty acids (FFAs) |
| PG-FFAs | 1 : 0.05 | 100% FFAs | PG-CA | 1 : 0.45 | 100% CA | PG-(CA, FFAs) | 1 : 0.5 | 90% CA-10% FFAs |
