This paper describes the preparation and the release properties of composite materials based on Pluronic F127 and gelatin hydrogels, which could be of interest in the field of enteral nutrition or drug administration. The composites were prepared by exploiting the opposite responsivity to temperature of a 20% w/w Pluronic F127 aqueous solution (critical gelation temperature around 23 °C) and gelatin (gel–sol temperature transition around 30 °C).
