Cross-linked two-parent films of PFOS and two-sex ion monomer sulfonyl beetline methyl acrylates were prepared and the properties of these films were tested for sample marine life.
defacement of marine structures poses problems for the marine industry, including increased fuel and operating costs. Many of the work and applications of chemical "fuzzy" two-parent coatings based on hydrophobic fluoropolymers and hydrophobic polyethyl glycol (PEG)
. Many of these coatings have shown good dirt release performance against diatoms, challenging the commercially available state-of-the-art silicone-based dirt release coatings.
, however, PEG is easy to oxidize, which limits its practical use in the marine environment and will therefore require alternative hydro-hydro materials in future development of two-parent coatings. In this regard, the two-sex ion material is becoming a promising type of hydro-friendly anti-fouling material, which researchers believe will be a suitable alternative to PEG in two-parent coatings.
Development and research of cross-linking co-parenting films
To test this hypothesis, a cross-linked parent film consisting of commercially available perfluoropolythers and two-sex ion monomer sulfonyl beetline methyl acrylics was developed and studied.
The dirt release properties of these membranes were tested on diatom Naviula incerta, a common microscale organism responsible for forming so-called "mucus" layers and having the anti-fouling properties of two barnacle species of golden turtle larvae (Balanus amtriphite and Balanus improvisus).
to expand the scope of the study, the clinically relevant biofilm-forming pathogen Staphylococcus acobacteria, which is responsible for infections and malfunctions in millions of medical devices, was also evaluated. The results showed that the addition of both sexes ions to perfluoroform ethers led to a significant improvement in the release performance of scale, and these parent coatings showed potential in scale release applications.
the study was published in March 2020 in volume 140 of Organic Coatings Progress.
