The use of PM coated plastics have for some time now been sporatically used in cuting edge tech, which now is becomming widely used in everyday applications.
It's apparent that cost effective innovations in the electronics / electrical applications industries are turning to the use of plastics coated with nanofilms of gold, silver, PGMs, and REEs... moving away from silicon based materials that have proven fragile and immaleable.
Industries of note are the flexible touchscreen and flexible photovoltaics manufacturers, who are now producing these applications in todays tech... here are a few articles:
Nanoscale gold coatings made easy
New flexible memory devices rely on gold
Organic Photovoltaic Devices
This article gives info on the layering of gold at around 7–8nm in thickness, applied directly onto a plastic substrate. Whether this can be used as a guide for every PM coated plastic application I don't know, however the touchscreen plastic applications use silver nanowire bonded with gold connections.
Silver, Gold Makes for Cheap, Flexible Touch Screens
Noteable recapture purities of PMs stripped from these plastic surfaces however should be substantially higher than when stripped with overlayed or alloyed base metals, it however would take a substantially higher amount of these coated materials to acquire noticeable value quantities I suspect...
Wiley's online library covers some of these technologies, if you have a paying membership you could get the articles covering these standards. The linked article is on Photovoltaics: Photovoltaic Properties of Glutathione-Protected Gold Clusters Adsorbed on TiO2 Electrodes.
Here's a rather interesting article... Technology Could Transform Windows Into Generators
If anyone has found materials containing these technologies, please post any info / images of it. I'll keep my eyes opened...
