Biggles’s Chewing gum NOW WITH GRAPHENE !!!!
Latest buzzword - not really a solution for everything (we have heard lots of claims over the last century for so many whizzbang things that didnt pan out ...)
Needs more information that the graphene (electrical properties, large surface area property, structural property ? ) How this will *IMPROVE* water filtration systems ?
Old activated charcoal filters opened binding points on the carbon atoms (and had tiny granules for max surface area). Graphene is a 2 dimensional carbon matrix - if you start ‘activating’ it you destroy its structure. So it sounds like it is some other mechanism to be employed for its filtration effect - electrostatic attraction ?? (charged surface perhaps like in many fancy air filters) - which though only works on certain types of pollutants.
SO another incremental advancement which probably will require other process improvements (like mass graphene production) to make it viable for mass use.
Mass production of graphene - not so good yet - water filters will use alot
Many labs have come up with novel ideas for mass graphene production. I’ve posted some of them here in the past.
Technically graphene is three dimensional. It is only one atom thick, but that thickness makes it 3 dimensional. Current production methods do not produce economical large area graphene.
