Surface hydrophobic modification of polymers with fluorodiazomethanes
Two fluorinated diazomethanes were synthesized, and used for the modification of polystyrene XAD4, polyacrylate MAC-3, filter paper, and Hybond™ membrane. The structure of modified polymers was confirmed by XPS and solid-state NMR spectra, with a surface loading of 8.28 × 10 12 –1.68 × 10 13 molecu...

| Summary: | Two fluorinated diazomethanes were synthesized, and used for the modification of polystyrene XAD4, polyacrylate MAC-3, filter paper, and Hybond™ membrane. The structure of modified polymers was confirmed by XPS and solid-state NMR spectra, with a surface loading of 8.28 × 10 12 –1.68 × 10 13 molecules per cm 2 . Water contact angle values, which increased from 0° to 128.51° (for filter paper) and 120.02° (for Hybond™ membrane), demonstrated hydrophobicity. |
