Graphene spray and ...

I agree with Geoff’s comment about the 200x factor. (Gee, that’s the second time in a week I’ve agreed with him :-))

As can be seen in this Samsung press release the 200x factor applies to "electron mobility," not to signal transmission speeds. As can be seen in the Wikipedia writeup, electron mobility is defined as the ratio of electron drift velocity to the strength of the electric field which causes that electron drift. As was recently discussed here in the Cerious Technologies thread electron drift velocity is **vastly** slower than signal propagation.

Basically, what Samsung is envisioning is that the use of graphene can potentially lead to integrated circuit devices, such as computer CPUs and other microprocessors, that internally are much faster than what can be achieved with traditional technologies.

With manufactures expressing that success with graphene is very dependent on application, some time and experimentation will likely be required.

It may have a benefit in speaker driver surrounds as its structure in rubber aid in rebound. We've also seen carbon epoxy implementations that may add to driver diaphragms that are carbon composite. Likely reduction in distortion and further frequency response range before breakup. Some speaker cabinets may benefit with its application.

It was thought that graphene could be use in voice coil as yarn had been recently developed, but now that stanene outed as graphene's tin derived cousin and it shows now resistance at all until 100C, it may become bypassed as a conductor.

The Mat-Sci lab is going to be an interesting place be and I have little doubt some will end up in audio products at some point. Might be a bit until affordability makes it more than just a lab experiment though.

Hey jeeter, not better; but, maybe 'faster' ?? lol

Geoffkait, once we're talking faster than the speed of light-I think it's getting "verry interestink" per Sgt. Schultz

Thanks almarg.
If new graphene technology can make our 
preamp,amp and digital equipment 'faster' I think 'cleaner' signals will be the result; giving us better sound.
