What makes tape stick?

[JDErickson]

Is it chemical bonding between the materials or an interleaving of the molecules? Like velcro?

[wacki]

Yes and no, it varies from glue to glue. Some glues work simply by creating a microscopic lock and key mold to lock materials together. Others use hydrogen bonds, Van der Waals bonds, ionic bonds, covalent bonds, or any combination of the above.

heheh

i think you just made someones list

van der Waal's forces make up some of it, but these forces aren't very strong . The theory on stuff like Scotch tape is that there are little air bubbles caught bewteen the weak adhesive that creates a suction effect. All of these little suction cups cause the tape to stick much better then inter-molecular forces would suggest.

Goo is what tape is all about. Goo is what makes it tape. Without goo, it would just be paper.
