Four block polymers with poly(cis-4,1-isoprene) (PI) contents ranging from 0 to 36 wt % delineate a trade-off between separation performance and mechanical robustness in membranes. The dataset likely contains bulk mechanical testing results and membrane performance metrics for specimens with an overall number-average molecular weight of Mn ≈ 100 kDa. It was authored by Adam Mann and harvested by the Texas Data Repository.
Use Cases
- Modeling the relationship between rubbery midblock content and membrane toughness based on bulk mechanical testing data.
- Analyzing the trade-off between surface morphology disorder and molecular-weight cutoff (MWCO) based on phase-inversion conditions.
- Optimizing block polymer architecture for balancing pure-water permeance and poly(ethylene glycol) (PEG) rejection profiles.
- Investigating the transition from brittle to rubber-toughened thermoplastic mechanical response with increasing PI content.
Strengths
- Includes data for four distinct block polymer compositions with PI content ranging from 0 to 36 wt %.
- Reports high pure-water permeance values of approximately 1300 L m–2 h–1 bar–1 across the studied membranes.
- Links specific material properties (PI content) to both mechanical performance and separation outcomes.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
