Silica-Protein Hydrogel Rheology Approaching Phase Separation

Aggregating experimental rheology data for composite silica-protein hydrogels. It was created by Xiufeng Li and published in 2020 to study the impact of silica nanoparticle compatibility on mechanical properties as the system approaches phase separation. The data includes measurements of gel strength and fracture behavior across varying particle concentrations.

Use Cases

• Analyze the relationship between silica nanoparticle concentration and strain-at-break to identify fracture planes near phase separation.
• Model the frequency-dependent gel strength using oscillatory rheology data to differentiate high-frequency cross-linking from low-frequency network weakening.
• Investigate the correlation between particle concentration and viscous dissipation from shear-induced polymer desorption.
• Study the contrast between linear and non-linear rheological properties as signals for an approaching phase separation boundary.

Strengths

• Data is derived from controlled experiments on a specific telechelic protein-based polymer system.
• Findings are published and peer-reviewed, with a clear focus on the mechanics near phase separation.
• Dataset is openly available under a CC0 1.0 public domain license.

Limitations

• The specific number of data points, rows, or experimental replicates is not provided.
• Data is limited to one specific polymer-particle composite system (silica-protein), limiting generalizability.
• The dataset is from 2020 and may not reflect the most recent research in the field.
