Lightbulb Polymers prevent fouling bottoms?

Have been hearing about some new polymer technology being used to all the ketchup out of the bottle so to speak. Basically:

So what stops the ketchup sticking? This isn't nanotechnology, but chemical interactions between the food and the polymer which is designed to repel specific food groups. At the same time, it's hydrophobic which allows water to run off easily but, overall, this isn't the same as water-repelling clothing or self-cleaning glass.

So I am thinking of a use for us sailors- Perhaps we can find a way to add these polymers to antifouling paint creating a super slick surface that A. reduces drag and B. creates a super slick surface which prevents marine growth from being able to take hold.

Thoughts?

Re: Polymers prevent fouling bottoms?

Bottom treatments need to:
- be effective against critters that actively try to defeat them;
- last for some time (preferably years);
- not damage the surrounding environment;
- be affordable.

So far as I know, the polymers being developed for the food industry still need to demonstrate point uno.

If it can be done, the major paint manufacturers (multinational corporations all) would already be doing it.

So far, I'm hearing crickets from them.

Re: Polymers prevent fouling bottoms?

There is ongoing research (THE NAVY DOES A LOT and

The biggest drawback is a material that can be applied in the field in vastly differing conditions

For example you can kind of sort of glue down Teflon as we use a wide variety of tapes BUT they all just barely hold on and get changed pretty regular

Nawww; if they came out with something like that, you wouldn't have to keep buying their expensive noxious toxic potions each year.

Yeah, 'cause an anti fouling product based on a short-lived superhydrophobic formulation wouldn't be expensive to use.

Re: Polymers prevent fouling bottoms?

Are we talking about " neverwet "from Rust-Oleum ? The video about this mentions it is not very wear resistant. Its amazing stuff.

Re: Polymers prevent fouling bottoms?

At one time, when running sport fishing boats in Australia, we chromed our props, hoping to attract more marlin. Amazingly enough those props still fouled, even operating several days a week or more.
Those marine creatures that love to live on our bottoms and running gear are incredibly tenacious.
I have wondered if there was a way to get Never Seize to work as a bottom paint. Be great for racers, too.
