Talk:Self-healing material

Technical

This page is very technical.

It would be great if someone who knows about these things (ie not me!) could write a non-technical summary at the beginning.

I'd also be interested to know what self-healing mechanism so-called self-healing cutting mats use.

Cutting board

Yeah, I'd like to know too, or if those mats are even self-healing. The article for Cutting board talks only about the culinary kind, and this article doesn't list any uses for self-healing material. I'd be interested knowing what people plan on doing with such materials. Ron Stoppable (talk) 02:03, 16 October 2011 (UTC)

I wound like to know which organization founded "self-healing material".Picaxe01 talk 01:55, 13 October 2012 (UTC) University of Michigan — Preceding unsigned comment added by 141.211.182.53 (talk) 21:32, 15 March 2013 (UTC)

Serious Inaccuracies?

Two items are questionable:

• The statement "The first report of a man-made self healing material was by the group of prof Scott White of the University of Illinois" as insterted in 2006 by the user "Fongs" in [version here].

This cannot be considered accurate given the work for example in studying the discoveries of Roman Cement/pozzolanic mortars and the role in Hagia Sophia's resistance to Earthquakes.

• Second, in 2009, the user "Chem540f09grp11" replaced the entire foreword,

From this:

A self-healing material is a material that has the built-in ability to partially repair damage occurring during its service lifetime. Usually, certain properties of any engineering material degrade over time due to environmental conditions or fatigue, or due to damage incurred during operation. This damage is often on a microscopic scale, requiring periodic inspection and repair to avoid them growing and causing failure. Self-healing materials address this degradation through the inclusion of an "active" phase that responds to the micro-damage by initiating a repair mechanism. Several mechanisms have been proposed for a range of engineering materials (e.g. metals, polymers, ceramics, cemetitious, elastomeric and fibre-reinforced composite materials;). Most are currently under investigation at a laboratory or research scale.

Supported by the citation S. van der Zwaag (Editor). "Self-healing Materials: an Alternative Approach to 20 Centuries of Materials Science" 2007. (Dordrecht, The Netherlands: Springer).

To this:

Self-healing materials are a class of smart materials that have the structurally incorporated ability to repair damage caused by mechanical usage over time. The inspiration comes from biological systems, which have the ability to heal after being wounded. Initiation of cracks and other types of damage on a microscopic level has been shown to change thermal, electrical, and acoustical properties, and eventually lead to whole scale failure of the material. Usually, cracks are mended by hand, which is difficult because cracks are often hard to detect. A material (polymers, ceramics, etc) that can intrinsically correct damage caused by normal usage could lower production costs of a number of different industrial processes through longer part lifetime, reduction of inefficiency over time caused by degradation, as well as prevent costs incurred by material failure.

This is supported by one citation (Zang, M.Q. (2008). "Self healing in polymers and polymer composites. Concepts, realization and outlook: A review". Polymer Letters.)

The problem is that it the current version gives the impression of restricting the term "self healing Material" to "Smart Materials". :I believe the earlier version was more accurate and more inclusive and therefore is not taking a "position". I also think that to talk about a material having "inspiration" is not correct.

I would therefore propose moving the text back to how it was

(any comments please put on my talk page too)

Links to wrong page

In the History -> Materials science section, self-cleaning materials seems to link to an unrelated article. I don't know how to fix this, but I wanted to point it out. 2603:3020:1B01:3700:EFA8:1AD:CFE2:46E5 (talk) 22:21, 5 October 2022 (UTC)
