Molecular Velcro
A material made of similarly shaped particles that stick to eachother by hooking similar parts of their shapes | |
The idea would be that a material made out of lots of little
particles with similar shapes that could link into fastened
structures would have interesting properties -- it would act
like a liquid under a certain amount of presure from a solid
object, but "freeze" and hold its shape as the presure
from
that object was lessened.
Maybe the shape of each particle could be like a cube with
each corner twisted into a widening corkscrew hook -- or
maybe a cube with lots of little corkscrew hooks on its surface
would work better.

What does the H stand for? |
|
| |
It's to remind you that in Spanish it's pronounced 'Haysoose'. |
|
| |
This sounds like the glue on 3M's Post-It notes. |
|
| |
A related material: micro paperclips. Shaking a mass of them causes them to cross-link, forming a gel. |
|
| |
"it would act like a liquid under a certain amount of presure from a solid object, but "freeze" and hold its shape as the presure from that object was lessened." kind of sounds like clay. |
|
| |
Molecules that bind with other molecules due to matching shapes are used every day - that's how our body fights germs. |
|
| |
But on the whole, molecular bonds are extraordinarily difficult to part - that is why most solids stay that way, rather than collapsing into piles of dust. So when you manage to stick two molecules together, they will likely stay stuck. |
|
| |
You might very well find molecules that will bind and unbind in your magic chemistry set, but I suspect do will do so under different conditions than the ones you specify. I think your best bet would be an applied electric field. |
|
| |
Otherwise, stick with Blutak. Or, per Detly, Post-Its. |
|
| |
"A gecko's foot contains millions of minuscule hairs, or setae, with tiny pads at their tips. Because they are only 200-billionths of a meter wide, the tips get close enough to any surface to be pulled by the surface's weak molecular forces. The combined strength of all the setae on a single gecko, Dr. Autumn found, is enough to lift an offensive lineman, about 280 pounds." |
|
| |
This 'van der Waal' weak force will keep the moleclules bound but not chemically, so removing them is a matter of peeling them off like a suction cup. |
|
| |
"I'm not a scientist, I'm just drawn that way." |
|
| |
Ferro-fluid might be of interest. It normally flows like liquid until a magnetic field is applied, then it solidifies. Good for halfbaking. |
|
| |
As is a bottle or two of wine. What were we talking about again? |
|
| |
I was thinking, allbeit not so eloquently, that the
individual particles could be any size, say the size of golf
balls. |
|
| |
"the individual particles could be any size, say the size of golf balls" |
|
| |
So this is a new kind of velcro on a larger scale than regular velcro? |
|
| |
You might want to change the name of the invention then. |
|
| |
Or on the same scale as regular velcro, just not only
micro level. Maybe Modular Velcro minimal units, velcro
particles, Velcro
individuals, Velcro balls? |

//it would act like a liquid under a certain amount of presure from a solid object, but "freeze" and hold its shape as the presure from that object was lessened." kind of sounds like clay// Sounds more like....anti-custard! |

See link: when things are that small, you don't need hooks and loops - things just stick to eachother anyway. |
