Seeing as we are unable or unwilling to deal with the present micro and nano-particles resulting from decades of plastic use and disposal, I worry about the environmental effects of graphene.
- CalRobert 10y agoCan anyone with experience in the topic comment with regards to graphene decomposition? A few things I've found: https://en.wikipedia.org/wiki/Graphene https://en.wikipedia.org/wiki/Graphene "10 µm few-layered graphene flakes were able to pierce cell membranes in solution" http://www.kurzweilai.net/graphenes-negative-environmental-impacts http://www.kurzweilai.net/graphenes-negative-environmental-i... "In groundwater, which typically has a higher degree of hardness and a lower concentration of natural organic matter, the graphene oxide nanoparticles tended to become less stable and eventually settle out or be removed in subsurface environments. In surface waters, where there is more organic material and less hardness, the nanoparticles remained stable and moved farther, especially in the subsurface layers of the water bodies." (also http://online.liebertpub.com/doi/abs/10.1089/ees.2013.0392 http://online.liebertpub.com/doi/abs/10.1089/ees.2013.0392)
- Neliquat 10y agoAbspestos 2.0 Funny enough, its not actually banned in the USA, just a liability nightmare. I ocasionally still see brake pads with the stuff. I suspect graphine, and other 'nano' materials will be similar in practice.
- BrendanD 10y agoThat would be _malpractice_.
