Polymer Membrane Performance Data for CO2 Capture with g-C3N4 Nanosheets

Long Cheng from Nanjing Tech University synthesized g-C3N4 nanosheets from dicyandiamide and melamine monomers and incorporated them into polyether block amide membranes. The dataset likely contains experimental results on gas permeance and selectivity, specifically for a membrane with 0.25 wt% DCN-4 nanosheets showing enhanced CO2/N2 separation. The data supports research into tunable adsorption and molecular sieving properties for carbon capture applications.

Use Cases

• Training predictive models for CO2 permeance based on nanosheet synthesis parameters like monomer type and etching time.
• Analyzing the relationship between CO2-philic properties and gas solubility/diffusivity in polymer matrices.
• Benchmarking the separation performance of modified membranes against pure Pebax membranes.
• Investigating the long-term operational stability of nanocomposite membranes for industrial CO2 capture.

Strengths

• Data is derived from systematic investigation of CO2-philic and molecular sieving properties, as stated in the description.
• Identifies an optimal material configuration (DCN-4 nanosheets at 0.25 wt%) showing simultaneous enhancement in CO2 permeance and selectivity.
• Includes results from a long-term operation test, indicating stability data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
