A material as strong as graphene may have curious abrasive properties.
- cjfont 13y agoI doubt the final product will be pure graphene, I'm sure it'll be thinly coated with something else (Teflon?)
- jimmaswell 13y agoIsn't it not recommended to put Teflon inside of yourself or am I misremembering something?
- refurb 13y agoThey use telfon in all sorts of implants. I don't think there are really any safety concerns.
- Double_Cast 13y agoIf Teflon were anymore inert, it'd be a noble gas.
- ars 13y agoTeflon is extremely inert, but it's not quite as inert as a noble gas - the c-c bonds can dissociate and burn. (The f-c-f bonds can't.)
- etler 13y agoTeflon is actually completely inert in your body. It's only a problem if it is heated to the point of giving out fumes at 260 celsius, and I hope that isn't happening in the bedroom...
- dhughes 13y agoTeflon or PFOA is supposedly in everyone's blood already at least in the US and probably most western nations it's so pervasive. https://en.wikipedia.org/wiki/Perfluorooctanoic_acid https://en.wikipedia.org/wiki/Perfluorooctanoic_acid
- ars 13y ago> Teflon or PFOA Teflon and PFOA are not the same thing! Teflon is made from PFOA true, but the properties of the two are quite different. Teflon is completely inert, PFOA isn't.
- robabbott 13y agoI had read in another source that it would be a mixture of graphene and latex. Surely it will have some kind of lubricant.
- colanderman 13y agoDoesn't graphite (a close relative of graphene) have lubricative properties?
- vacri 13y agoA locksmith tried to fix our sticking front door lock with a bit of graphite spray, which I hadn't seen before.
- emhart 13y agoScribble a pencil on a piece of paper for a while, fold it in half, blow the dust into the lock and run the key in and out a few times. Works like a charm.
- wmeredith 13y agoYep. We had graphite gel and spray for our pinewood derby axles in Boy Scouts.
- Wingman4l7 13y agoSame here -- graphite lubricant was the standard stuff.
- miga 13y agoMost condoms today are enhanced with advanced lubricants.
- avn2109 13y agoTribologist here, about to publish a study of reciprocating friction and wear in graphene-loaded plastic composites. We see two orders of magnitude wear reductions at 30,000 cycles for 10% graphene by mass (dry reciprocating conditions) and suppression of the abrasive wear mode. Also friction coefficient goes down by 10%, but other studies have reported much bigger friction coefficient improvements.
