This article explores the insights provided by infrared (IR) spectroscopy into the optical properties and surface morphology of polyethylene (PE) polypropylene (PP), and polyvinyl chloride (PVC) films. Notably, IR spectroscopy can identify absorption lines attributed to various functional groups in addition to those associated with lower-density linear polyethylene. The specific characteristics of IR spectra for linear low density polyethylene are influenced by polymer processing conditions, branching, and monomer content. Moreover, the IR spectrum of PVC offers valuable information about its molecular structure and composition. Comparatively, polypropylene (PP) films exhibit higher absolute light transmission in the ultraviolet and visible spectrum when contrasted with films based on PE and PVC. The utilization of atomic force microscopy (AFM) and IR spectroscopy reveals that heat-induced decomposition and subsequent cooling do not impact the surface roughness or thickness of the films, confirming the retention of structural and electrophysical attributes.
