Has anyone tried coating a paper cone woofer with graphene auto detailing spray?
Just another dump idea. LOL
Thanks,
Scott

Have you tried it yourself, Scott, prior to asking?
A graphene-based ink could be sprayed onto a paper woofer cone to provide a coating that improves mechanical strength.
Printable graphene inks have been developed for a range of applications such as heating elements, flexible and bendable electronics, and textiles for wearable technology.
I don't know if it's wise to use "graphene auto spray" on a paper cone as the degree of wetting may have a deleterious effect. However, it may bring a bit of shiny bling to a plastic cone!

At £265 for 100g of graphene printing ink, you are darn tootin'!

And what's more, that particular ink is designed to be "low temperature" cured at 120˚C.
Given how new Graphene is as a commercail project, i would be very concerend that many of these products having “graphene” in them could well be a marketing thing.
Grapene does have some ionteresting properties, and we know that some coatings defiantly work. Try it and report your results

I've been fact checking, Dave!
Graphene detail sprays do not actually contain graphene, but contain graphene oxide (GO).
GO is made by the chemical oxidation of natural graphite which is a crystalline form of carbon.
GO is a precursor of graphene, meaning it is a substance from which graphene may be formed.
GO's mechanical strength is describe as strong, but less so than graphene. It is also described as being flexible and elastic.
For the geeks out there: https://www.ossila.com/pages/what-is-graphene-oxide#:~:text=Graphene oxide (GO) is oxygen-functionalized graphene. It is,polar solvents and tunable electrical and optical features.
Learning all the time! 😎
Yes SEAS metal cones, fancy materials, marketing hype and some resonance damping of the breakup.
Did you ever try the good old Aquaplas? Has a proven track record on paper cones and compression driver diaphragm, and a whole lot of other uses for samping vibration and resonances in buildings, ductings, ship hulls etc. is easily available and not really expensive.
Just try to beat my trick! Reversible and various size and weight... Perhaps a too cheap trick for 50% reduction of resonance amplitude?

Easy to test the best distribution of pads! And size, thickness (=weight)

Graphene is used in some fishing rods, added to the resin impregnating the usual carbon fibre in the blank (and whatever else is used in the particular rod in question).
Also bein gused to replace steel reinforceing oin concrete, allowing for the same strength with much less material.

Never tried coating paper cones with carbon foil. Maybe one day I will.
It should be really thin hoping it does not resist then being strechted to a Nawi cone.
Never tried Titanium foil for the same reason.
