Like other polymers, the long molecules are not laid out in straight lines but become entangled during manufacture, like long strands of spaghetti. Silly putty is described as being …

2012年10月1日 · We consider in this paper the elastic and viscous properties of Silly Putty and confirm the well known fact that the properties depend on the rate at which the material is …

Under stress, the bonds can be broken over a relatively long time scale and the strands can be untangled. Hydrogen bonds can reform over the same time scale.

2019年10月11日 · Students synthesize polymeric materials and create two different formulations of imitation Silly Putty. Then they design new versions of the putty that satisfies one of two …

Silly Putty. Description: Silly Putty is a silicone polymer which is a non-Newtonian fluid, similar to slime. It has dilatant properties; it expands when sheared, resulting in an increased viscosity …

2016年5月2日 · New insights into the characteristics of collagen, the protein that provides structure and stability for cells but which also stretches like Silly Putty, could help scientists …

2013年11月6日 · A new method was developed for quantitative determination of the viscoelastical characteristics of hyaluronic acid (HA) putty (formed at pH 2.5) using a stress relaxation …

2016年5月4日 · Writing in the Proceedings of the National Academy of Sciences, the researchers report that the stiffer collagen networks become in response to a deformation, the more quickly …

Writing in the Proceedings of the National Academy of Sciences, the researchers report that the stiffer collagen networks become in response to a deformation, the more quickly they relax …

2020年2月25日 · Students learn about viscoelastic material behavior, such as strain rate dependence and creep, by using silly putty, an easy-to-make polymer material. They learn …
