Talk:Adhesion

Suction Cups?
What type of adhesion do suction cups fall under?--DataSurfer 21:37, 2 October 2006 (UTC)
 * Suction cups don't work (primarily) by adhesion. They are held onto the surface by atmospheric pressure and held in place by friction. —Ben FrantzDale 19:26, 17 January 2007 (UTC)

Water
There are three pictures of water adhering to different things. How does that work? Is it related to the hydrogen-bond cohesion? Askewchan 10:02, 12 February 2007 (UTC)

Molecular attraction?
One of the mechanisms listed, mechanical adhesion, isn't attraction on a molecular level -- which is how adhesion is defined in the first paragraph. Are we sure that adhesion ONLY refers to "sticking" that occurs at a molecular level? In which case, it would seem that mechanical adhesion, such as velco wouldn't qualify; and if not, what would you call it when things stick to one another but not at a molecular level? Limbo socrates 21:38, 26 July 2007 (UTC)

the first paragraph does not say that adhesion is defined as only being on a molecular level, but more importantly, mechanical adhesion does happen on a molecular level. Stringing is one example. It is somewhat analogous to velcro on a molecular scale. —Preceding unsigned comment added by 98.227.75.175 (talk) 23:12, 18 April 2010 (UTC)

Meniscus
How does adhesion affect the meniscus of a test tube? If there's very high adhesion, is the meniscus concave or convex? —Preceding unsigned comment added by 24.247.43.141 (talk) 03:37, 12 December 2009 (UTC)

If high ADhesion, concave (adheres to glass in tube); if high COhesion (to itself) then convex. Art4med (talk) 03:20, 24 December 2012 (UTC)

Proposed merge with adhesive surface forces
These articles cover the same topic therefore they should be merged. Plus ASF is an orphan. Wizard191 (talk) 17:56, 16 April 2010 (UTC)


 * this article discusses the specific mechanisms by which surfaces adhere to one another from a materials science perspective. it has a focus on technical mathematical models, and simply adding it to the adhesion page would disproportionately increase the technical details regarding surface adhesion mostly as an application of materials engineering. i agree that its status as an orphan needs work, wouldn't it be better to link up this page with Adhesion, Sticky Tape, Glue, Biomimetics, van der Waals forces, etc? —Preceding unsigned comment added by 98.227.75.175 (talk) 22:59, 18 April 2010 (UTC)


 * Yeah this page needs help in general. I think there is a lot of redundancy between the two articles right now that can be eliminated if they are merged. Just because the incoming text is a little more technical doesn't mean it shouldn't be merged. Wizard191 (talk) 16:03, 19 April 2010 (UTC)
 * Support merger. Rlsheehan (talk) 13:41, 25 September 2010 (UTC)

Assessment comment

Hydrogen bonding listed under "chemical adhesion".
Hydrogen bonding is a kind of dipole-dipole bonding (Keesom forces) that involves hydrogen, and is therefore a very strong kind of dipole-dipole bonding. Given how Keesom forces are a sub-category of Van der Waals forces, shouldn't hydrogen bonding be mentioned under the dispersive category, and not the chemical category? Also, I noticed that Debye forces were missing from the dispersive category as well, but perhaps adhesion via Debye forces doesn't happen due to the dipole-containing substance's preference towards cohesion rather than adhesion in cases where its met by a non-polar substance? If this is the case, perhaps this should be mentioned in the category of dispersive adhesion?

wrong link
The link from "mechanical effects" at the end of the 2nd paragraph links to the special effect page instead. 209.104.123.250 (talk) 12:23, 17 October 2023 (UTC)
