Article Synopsis
- Alginates are gaining popularity because they are both biocompatible and biodegradable.
- Researchers created alginate films with varying glycerol and calcium chloride concentrations to see how these factors affect their properties.
- The study found that combining glycerol and calcium improves the mechanical strength and thermal resistance of the films, making them suitable for applications like wound dressing and food packaging.
Stress relaxation and humidity dependence in sodium alginate-glycerol films.

Article Synopsis
- The viscoelastic properties of alginate biopolymer are crucial for its effectiveness in biomedical applications, mimicking biological matrix properties.
- Stress relaxation of glycerol plasticized sodium alginate films is tested at two humidity levels, showing that glycerol concentration significantly influences relaxation behavior.
- Specifically, films with 30% glycerol exhibit a drop in normalized stress from 65% at low humidity to 8% at high humidity, while glycerol-free films show higher stresses, indicating the need for careful modeling of relaxation time, especially for lower glycerol concentrations.
