| Popis: | Porcine plasma protein (PPP), a by-product of the meat industry, is considered for the development of eco-friendly superabsorbent materials due to its relatively high content in polar amino acids. Using glycerol (Gly) as plasticizer, different PPP/Gly ratios (50/50, 55/45, 60/40) were injection moulded at different moulding temperatures (60-120 °C). It is noteworthy that all bioplastics produced might be defined as superabsorbent materials, except those processed at higher moulding temperatures (100, 120 °C). Bioplastics moulded for 150 s at lower temperatures (60 °C) and using a holding pressure of 500 bar displayed the highest water uptake capacity (∼2,530%). Moreover, these processing conditions also resulted in lower thermomechanical properties. PPP represents an attractive and economic bioresource for the production of biodegradable superabsorbent matrices, which could represent an alternative to the extensively used synthetic materials. |
