General description

2,2,3,3,4,4,5,5,6,6,7,7-Dodecafluoroheptyl acrylate (DFHA) is a fluorous functional monomer that is majorly used in the surface functionalization. It can also be utilized in chemical vapor deposition process for the synthesis of nanomaterials.

Application

DFHA can be used in the preparation of hybrid fluorous monolithic columns for nano-liquid chromatography. It can be used in the surface modification of multi-walled carbon nanotubes (MWCNTs) for the formation of highly conductive composites.

A hybrid fluorous monolithic column was simply prepared via photo-initiated free radical polymerization of an acrylopropyl polyhedral oligomeric silsesquioxane (acryl-POSS) and a perfluorous monomer (2,2,3,3,4,4,5,5,6,6,7,7-dodecafluoroheptyl acrylate) in UV-transparent fused-silica capillaries within 5min. The physical characterization of hybrid fluorous monolith, including
