Unlikely uses of graphene

Did anyone have car wax on their card? https://www.turtlewax.co.uk/collections ... w/graphene

There’s a truism in materials science that advances are led by the military and sports - because these are fields where people are prepared to spend money to gain advantage, so I’m less surprised to see graphene in a sports context.veravista wrote: ↑Wed Mar 16, 2022 10:15 amGolf balls and now golf shafts....

You can get “graphene grip” running shoes as well.

There’s a lack of standardised testing that would demonstrate a clear advantage. I can imagine lots of tests that could be done, but I don’t think manufacturers are keen on cross-brand comparisons, and certainly wouldn’t pay for them. It’s only when safety is involved (E.g. helmets) that standard tests get used.shpalman wrote: ↑Wed Mar 16, 2022 11:21 amIt's been in skis and tennis rackets for a while now.Grumble wrote: ↑Wed Mar 16, 2022 10:37 amThere’s a truism in materials science that advances are led by the military and sports - because these are fields where people are prepared to spend money to gain advantage, so I’m less surprised to see graphene in a sports context.veravista wrote: ↑Wed Mar 16, 2022 10:15 amGolf balls and now golf shafts....

Sports people also do all sorts of superstitious and pseudoscientific b.llsh.t because they feel like they gain an advantage from doing so, but I'm totally sure graphene has been scientifically demonstrated to give an advantage and isn't just leveraging some fashionable science to make more money off of people.
When does graphene become graphite? I'm not sure I would want to use skis that are a single atom thick.shpalman wrote: ↑Wed Mar 16, 2022 11:21 amIt's been in skis and tennis rackets for a while now.Grumble wrote: ↑Wed Mar 16, 2022 10:37 amThere’s a truism in materials science that advances are led by the military and sports - because these are fields where people are prepared to spend money to gain advantage, so I’m less surprised to see graphene in a sports context.veravista wrote: ↑Wed Mar 16, 2022 10:15 amGolf balls and now golf shafts....

One area where there is standardised testing is golf balls. Precisely to try and prevent an arms race in golf balls, there are regulations for golf balls based on standardised testing. When struck by standard test apparatus, a permitted golf ball must depart by no more than a specified maximum speed, and travel no further in total than a standard maximum distance, presumably based also on some standardised terrain.various people wrote: Golf balls and now golf shafts....

I'm totally ignorant of graphene and material science, but why is graphene better than graphite for reinforcing polymers? I don't understand the structural benefits of the graphene being super thin. Is it just that you get more 'pieces' of graphene per mass of carbon?shpalman wrote: ↑Wed Mar 16, 2022 11:38 amWell, the "graphene" in this case is probably small flakes of thin (one-to-few monolayer) graphite mixed in with whatever the rest of the material is.
The Cosmic Collection introduces a new direct-ion for Graphene Plus.
A single sheet of graphene is strong. If you have more sheets, such that you have thin graphite, then the sheets can easily slip over each other. So it's much less strong now, assuming when you pull on two ends of it you don't have hold of the same sheet.WFJ wrote: ↑Wed Mar 16, 2022 5:02 pmI'm totally ignorant of graphene and material science, but why is graphene better than graphite for reinforcing polymers?

That could certainly be a benefit for some properties, a finer dispersion of particles would increase homogeneity for example. It might mean an increase in stiffness as well.WFJ wrote: ↑Wed Mar 16, 2022 5:02 pmI'm totally ignorant of graphene and material science, but why is graphene better than graphite for reinforcing polymers?

Somewhat surprisingly, the *claims* for the graphene in the running shoes are not really related to sporting performance as such.Grumble wrote: ↑Wed Mar 16, 2022 11:25 amThere’s a lack of standardised testing that would demonstrate a clear advantage.

Are there any graphene helmets? I’ll just go off and research.
