CO2 Separation Performance Data for PEBAX Membranes with Polystyrene Nanoparticles

Experimental data from a study comparing freestanding and thin-film composite membranes for CO2/N2 separation. The dataset likely contains measurements of permeability, selectivity, and nanoparticle loading percentages, as described in the research summary authored by Jun Seok Hwang and uploaded to figshare in April 2026. The data illustrates the effect of membrane structure and nanoparticle organization on gas transport properties.

Use Cases

• Modeling the permeability-selectivity trade-off based on nanoparticle loading percentages mentioned in the description.
• Comparing bulk free-volume enhancement versus interfacial diffusion control mechanisms based on membrane configuration data.
• Analyzing the relationship between crystallinity reduction and gas diffusivity in freestanding membranes as described.
• Evaluating the impact of shear-assisted nanoparticle alignment on selectivity in thin-film composite membranes.

Strengths

• Includes specific performance metrics such as CO2 permeability of 198.6 Barrer and CO2/N2 selectivity of 41.4 for freestanding membranes.
• Compares two distinct membrane configurations (freestanding and thin-film composite) with defined thicknesses (~100 µm and ~250 nm).
• Reports optimal nanoparticle loadings (10 wt% and 20 wt%) with quantified performance improvements over pristine material.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small (26.6 KB), indicating limited scope.
