Modern polymers are seldom used as pure materials, more often mixtures of different polymers are combined to give the desired physical characteristics. For example, the rigidity of polystyrene is often combined with an elastic polymer to produce stiff yet shock resistant materials. Polymeric laminates are important in the microelectronics, medical, food packaging, and chemical industries. Since, laminates act as moisture and/or oxygen barriers they are commonly used to protect foods and chemicals. There are many methods that can be used to generate these mixtures but one of the most common is to simply assemble the polymers into layers and create a laminate. The most widely used structural spectroscopic measurement for laminates is Fourier Transform infrared (FTIR). FTIR spectroscopy is a non-destructive technique that that allows chemical identification of the component materials in the laminate. Infrared spectroscopy provides the ability to study the interactions of the vibrational and rotational energies of atoms or groups of atoms within molecules.
