Hyper-crosslinked polymeric ionic liquids (HCPILs) based chainmail adsorbents for highly efficient gaseous toluene capture under high humidity

Key Points

• The aim is to develop a highly effective adsorbent for capturing toluene in high humidity conditions.
• Developed Cu-BTC@HCPIL adsorbents through surface engineering of metal-organic frameworks.
• Evaluated adsorbent performance under 80% relative humidity.
• Measured water contact angle to assess hydrophobicity.
• Achieved a water contact angle of 109.6°, indicating strong hydrophobic properties.
• Demonstrated effective toluene capture despite high humidity, showcasing its potential use in real-world applications.
