Description
The composition and structure of an ablative polymer has a multifaceted influence on its thermal, mechanical and ablative properties. Understanding the molecular level information is critical to the optimization of material performance because it helps to establish correlations with the macroscopic properties of the material, the so-called structure-property relationship. Moreover, elucidation of the molecular structure is also essential to predict the thermal decomposition pathways as well as to identify decomposition species that are fundamentally important to modeling work. In this presentation, I will illustrate the use of infrared transmission spectroscopy (FT-IR) as a convenient tool to elucidate the structures of several major classes of ablative polymers.
