Scientists have been using hydrogels in medical technology since the 1980s, but their lack of rigidity and durability limited their use. But by adding a small amount of clay to the mixture, the researchers succeeding in imbuing the hydrogels with the stiffness needed to make the material more versatile.
The clay enhances the hydrogel because the polymer used to bind the water into a gel simultaneously adheres to the clay, the water, and other polymer chains. By grabbing all the elements, the polymer forms a rigid scaffolding that supports the other molecules, and creates solid material. Plus, because the material is mostly water and clay, with only a little bit of polymer, the material has none of the toxic qualities of plastic.
In their paper in Nature describing the new material, the University of Tokyo researchers fail to address the cost of this new hydrogel. One of the key advantages of plastic is the low cost, and no material can be considered a viable replacement for plastic until someone can manufacture it just as cheaply.
Could it be used in 3-D printing being ecologically friendly?
umm, while it does have a lot less plastic in it, it still has plastic in it. So don't go crying the green rainbow of love that the world is saved yet.
but still, its a great improvement only "Less than 0.4 percent of it is petroleum-derived" as the article from the link says, which could easily change the damage of plastic from enormous to small.
<Im Awsome>lol I think its a good idea but I am working on stretchable steel which so far isnt working out i have half of it right because it does have tensile strength but it still isnt as solid as steel any ideas
<Im Awsome>lol can anyone help me wiht my stretchable steel im really at a loss here i could use some help considering that im a thirteen year old boy.
Do we really need a replacement for plastic that is as cheap as plastic? With cheap plastic, we make cheap crap that brakes and is thrown away. maybe we should focus instead on longer lasting products and adapting our economy back to a system that doesn't rely on cheap crap breaking and having to be replaced with new purchases.
I work at a doctors office and listened to a story how in the process of purchasing a new ekg machine, the saleman told the doctors that they'd need a service plan and that the machine probably wouldn't last 3 years. They flipped their lids since their last ekg machine lasted 27 years.
I'm sure it's not completely the fault of plastic, but no doubt, the breakable crap based economy is very much enabled by plastic.
This is not a joke! The religion of Islam and its offspring Sharia Law are taking modern Europe as we know it. Muslims want Islam to take over Europe and North America and force women to cover up or be punished! Please educate yourself on this dire matter immediately
Hey azriel13 i think that i could help you with your problem but only cause you are a young 13 year old boy. But before i could help you i would need to take you out to a movie and maybe come back to my place for a candle lit dinner and some wine. So how bout it?
And you wonder why your account has been banned 4 times...wow
Agreed that it is a step in the right direction to getting rid of plastic. also agreed that most things made of plastic suck and fall apart.
Best. Comment thread. Ever.
This new invention is great... http://www.amerisleep.com/
