The present invention is directed to coated articles demonstrating a transmission of electromagnetic radiation having a frequency of 22 to 81 GHz in the range of 70% to 100%. The articles comprise substrates coated with curable film-forming compositions comprising a first film-forming polymer prepared from at least one hydrophobic monomer, a second film-forming polymer prepared from at least one hydrophobic monomer, and a curing agent. Upon application of the curable film-forming composition to the substrate to form a coating layer, the first film-forming polymer is distributed throughout the coating layer, and the concentration of the second film-forming polymer is greater at the surface of the coating layer than the concentration of the second film-forming polymer within the bulk of the coating layer. The present invention is also drawn to methods of mitigating contaminant build-up on a substrate using the curable film-forming compositions described above.

An object of the present invention is to provide a photosensitive resin composition having good liquid repellency. The photosensitive resin composition of the present invention at least contains a fluororesin having a crosslinking site, a solvent, and a photopolymerization initiator, and the fluororesin contains a repeating unit derived from a hydrocarbon having a fluorine atom.

A block copolymer is provided that includes a first block having pendant phosphorus-containing groups and a second block having fluorinated groups. Compositions containing the block copolymer as well as articles that include the block copolymer are also provided. The block copolymer can be used to provide a lower surface energy to a surface, particularly a metal-containing surface.

The disclosure provides an improved process for preparing oleophobic fluoropolymers. The resulting fluropolymers were found to be effective in imparting hydrophobic and oleophobic properties to porous polymeric membranes such as PTFE. The treated PTFE membrane can reach an oleophobic level of 6 or above, (according to the AATCC-118-1997 oil repellency test method) with a low air flux loss.
