Thermal Degradation and Identification of Heat-Sensitive Polymers. Applications of Pyrolysis and Distillation and Instrumental Methods of Analysis  Stuart C. Clough and Emma W. Goldman
An experiment for undergraduate teaching laboratories is described that involves the identification of samples of polystyrene and poly(methyl methacrylate). This involves the thermal degradation of the polymers (a destructive distillation) into their respective monomers. The monomers are then identified using infrared spectroscopy, proton nuclear magnetic resonance spectroscopy, and gas chromatographymass spectrometry.

Electropolymerized Conducting Polymer as Actuator and Sensor Device: An Undergraduate Electrochemical Laboratory Experiment  María T. Cortés and Juan C. Moreno
A trilayer formed by two conducting polymer films sandwiched around an adhesive polymer layer works as actuator and sensor simultaneously. This device can be bent up to 180 and it can be used as a sensing device of physical chemistry parameters such as cell temperature and electrolyte concentration. In this article, it is shown in a didactic way how to electrochemically synthesize ClO4-doped polypyrrole (PPy) films, how to fabricate a trilayer device, and how to evaluate its actuating and sensing capabilities. The required materials are simple and a complicated setup is not necessary.

Making and Using a Sensing Polymeric Material for Cu2+: An Introduction to Polymers and Chemical Sensing  Jean R. Paddock, Anne T. Maghasi, William R. Heineman, and Carl J. Seliskar
In this experiment, students will be introduced to concepts of polymer chemistry, chemical sensors, metal chelates, spectroscopy, and quantitative analytical methods. A polymer network is generated by students and consists of crosslinked poly(vinyl alcohol) blended with the polyelectrolyte poly(acrylic acid), which is then doped with the spectroscopically-active chelating agent PAN, 1-(2-pyridylazo)-2-napthol. All components of this hydrogel serve as an ion-exchange medium trapping cations that, when exposed to solutions of 2+ metals, can act as a material in a chemical sensor.

Introduction to Photolithography: Preparation of Microscale Polymer Silhouettes  Kimberly L. Berkowski, Kyle N. Plunkett, Qing Yu, and Jeffrey S. Moore
In this experiment, a glass microscope slide acts as the microchip. Students can pattern this "microchip" by layering negative photoresist on the slide using a solution containing monomer, crosslinker, photoinitiator, and dye. The students then cover the photoresist with a photomask, which is the negative of a computer-generated image or text printed on transparency film, and illuminate it with UV light. The photoresist in the exposed area polymerizes into a polymer network with a shape dictated by the photomask. The versatility of this technique is exemplified by allowing each student to fabricate virtually any shape imaginable, including his or her silhouette.
