Sodium Polyacrylate Gel Patches Analyzed with Electronic Nose and Rheology

A 30-day study of four partially neutralized sodium polyacrylate (PNSP) gel patches prepared with two different neutralization degrees. The dataset, created by Zhaoying Qi and last updated in April 2026, contains results from quality evaluation, rheological assessment, electronic nose testing, cryo-SEM, and TGA-MS analysis.

Use Cases

• Comparing rheological properties of polymer gels based on neutralization degree mentioned in the description
• Correlating electronic nose sensor responses with gel structure and formulation characteristics
• Analyzing thermal stability and mass changes in gel patches using TGA-MS data
• Evaluating the long-term stability of gel formulations over a 30-day period

Strengths

• Data covers a 30-day observation period for stability assessment
• Analysis integrates multiple techniques: electronic nose, cryo-SEM, and TGA-MS
• Dataset is openly available under a CC-BY-4.0 license

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Dataset is very small (5.5 KB), indicating limited scope or a summary of results
