Abstract

Sterilization-related treatments are commonly applied to hydrogel-based biomaterials, and rheological data provide a basis for describing their post-treatment material profiles. This data article presents raw oscillatory rheometry data from untreated calcium-alginate hydrogel samples and from samples exposed to ultraviolet irradiation, ethylene oxide treatment, steam sterilization, gamma irradiation, and high hydrostatic pressure treatment. The dataset was generated by amplitude sweep measurements using an Anton Paar MCR 102e rheometer with parallel-plate geometry at 37 °C. The deposited CSV files include point-by-point values for shear strain, shear stress, storage modulus, loss modulus, loss factor, torque, and complex viscosity. Corresponding plots show storage and loss moduli versus shear strain, storage and loss moduli versus shear stress, and complex viscosity versus shear strain. The files are organized by treatment group; gamma-treated samples are arranged by dose, and high hydrostatic pressure-treated samples by pressure level and number of cycles. The dataset can be reused to extract viscoelastic parameters, define the linear viscoelastic region using user-selected criteria, generate rheological profiles for untreated and treatment-exposed hydrogels, and support exploratory analysis and testing of rheological data-processing workflows.
