Paper Stronger Than Cast Iron

TaeKwonDood writes "All paper is made of cellulose, which at the nanoscale level is quite strong, but paper processing makes large, fragile fibers that break easily. Researchers in Sweden have have come up with a manufacturing process that keeps the fibers small, resulting in 'nanopaper' with over 1.6 times the tensile strength of cast iron (214 megapascals vs. 130 mPa). And since cellulose is the most abundant organic compound on the planet, it's cheap to use compared to other exotic, expensive-to-produce options — such as carbon nanotubes."

Great, but is it fireproof?

Or treatable to be fire-resistant?

I can see a lot of uses for it even if it isn't. But I can see some fairly awe-inspiring ones if it's possible.

I suddenly had an image of Japanese-style paper walls made of this stuff. I wonder how much this would cost after it becomes commonplace? Would it be a viable replacement for drywall or wood? Would it be a good insulator?

Interesting indeed.

Actually, you are probably right. More porous and stronger? Sounds like a new paper towel to me. Hmmm what other paper products do we use that might benefit?

Saturated paper products: Tar paper, sheetrock, and other products that are basically using paper to contain some other product, etc.

Non-saturated: string spindles et al, books, food and product packaging materials, shipping materials...

If it turns out that thicker pieces constructed with pressure or other methods, perhaps we'll finally get a throwaway computer or dvr case? Perhaps we'll find that a lot of carbon based plastics might be better created with nanopaper processes? How much oil would that save? How much cleaner could commercial enterprises become?

There are a lot of things that paper is only just a bit less suitable than some other product that creates pollution or distributes toxins either during creation or after it's use.

Obviously, I'm not the expert, but if this can make some of that come true it will be a very good thing.

After I ran 6.2 kilometer yesterday, I was feeling thirsty. So I drank 1.6 liter of water. It took 37 minute to walk back to my car. I fired it up, and saw that the engine was already 52 degree from sitting in the hot sun. I got home, and collapsed from exhaustion. I slept an entire 9 hour.

Adjective vs. noun usage?
