PALS Data on Polymer Membranes for CO2/H2 Separation Performance

Experimental data from a study on cross-linked polyethylene oxide membranes for gas separation. The dataset includes measurements of CO2 permeability and CO2/H2 separation coefficients for original and PEG-impregnated membranes, with results showing significant performance improvements. The data was authored by Shanshan Ji and last updated on 2026-04-10.

Use Cases

• Benchmarking gas permeability performance based on reported CO2 and H2 permeability values.
• Analyzing the effect of PEG impregnation on separation coefficients based on the described experimental procedure.
• Modeling the relationship between membrane weight gain and gas permeability changes based on the reported 47.0wt.% increase.
• Comparing separation performance of membranes with different end groups based on the investigation described.

Strengths

• Includes specific quantitative results, such as CO2 permeability increasing from 170 to 1457 Barrer.
• Reports precise separation coefficient changes, from 7.9 to 13 for CO2/H2.
• Data is openly licensed under CC-BY-4.0.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 5.5 KB, indicating limited scope.
