Abstract
A simple demonstration of viscoelasticity can be carried out by attaching a weight to a polymer film and watching it extend over time. For accurate and quantifiable data on the deformation, an electronic displacement sensor should be incorporated. Most of such sensors are expensive. Here, an optical mouse was demonstrated to provide accurate data at low cost. The experiment was also devised in a manner to allow students to learn about viscoelastic deformation experientially.

DoetschmanJournal of Chemical Education2006 83 (10), 1531Two polymer–plastics experiments were developed for upper-level chemistry laboratories. In the first experiment, students prepare plasticized biopolymer films from aqueous solution and measure the dependence of mechanical properties on chemical ...
