[PhysOrg] New plastics conduct electricity

Quote:
A newly discovered technique makes it possible to create a whole new array of plastics with metallic or even superconducting properties.

Plastics usually conduct electricity so poorly that they are used to insulate electric cables but, by placing a thin film of metal onto a plastic sheet and mixing it into the polymer surface with an ion beam, Australian researchers have shown that the method can be used to make cheap, strong, flexible and conductive plastic films.
Strong, flexible, conductive..
But god forbid the environmental impact of using this technology in large scale application.

On the other hand, imagine how much weight you could save by replacing copper, aluminum, etc. with plastic.

Cool, I can see this having many immediate applications.

Also, go Australian researchers!

Doubtful it will replace anything, silicon will still rule for PCBs with copper conducting fantastically in wires for cheap.

Edit: I stand corrected I was thinking too main stream.

Metals can be recycled, albeit expensively. Metals are going to be produced in enormous quantities, computers or no. Etc.

Different grades of plastic can not be recycled together.
Plastic does not biodegrade and has no real use if it can not be recycled.
Etc.

Step 1 Dissolve plastic in acetone.
Step 2 Pour acetone solution into mold.
Step 3 ???
Step 4 Profit with new action figure!

why? per say one uses this plastic to create a mp3 player, the user buys it and uses it for 2 years and then throws it in the recycling bin used for conductive plastics ... and then they recycle it

thats the best case scenario, worst case scenario we just dump all of that plastic somewhere and it sits there doing nothing (similiar to all the milions of old pc's) ... in comparison to metals in todays mp3 players plastics arent all that toxic

Defintely! I can see this being VERY useful for all sorts of portable devices and various cables and/or connectors/adapters of many kinds. You could make a phone very durable to drops and possibly waterproof.

I've been waiting for conductive plastic to go mainstream for many years. I look forward to more progress on this.
