To adjust wetting properties of organic surface by in situ photoreaction of aromatic azide

This article describes development of a simple and convenient method to provide stable low-surface-energy coatings on organic surfaces, by designing and synthesizing a surface-reactive molecule 4-azido-N-dodecylbenzamide, which bears an azide group as the reactive surface anchor and an alkyl chain a...

520 |a This article describes development of a simple and convenient method to provide stable low-surface-energy coatings on organic surfaces, by designing and synthesizing a surface-reactive molecule 4-azido-N-dodecylbenzamide, which bears an azide group as the reactive surface anchor and an alkyl chain as the hydrophobic tail. After the hydrophobic modification, rough organic surfaces with contact angle of about 0 degrees can change their surface wetting properties from superhydrophilicity to superhydrophobicity, whose contact angles are above 152 degrees and tilt angles lower than 5 degrees. Moreover, by changing the alkyl chain to a PEO segment, a similar concept can be used to adjust the surface wetting properties from hydrophobic (contact angle approximately 130 degrees) to superhydrophilic (contact angle approximately 0 degrees)
