The Use of Infrared Methods to Study Polymer Interfaces

摘要

The surfaces of polymers and interfacial reactions between polymers and other materials are of much interests to the coatings and adhesive industries. There are many techniques which are available to study these surfaces, but none can yield as much information about the chemical nature of polymer surfaces as infrared spectroscopy. In the past, such studies were severely limited by a lack of specialized surface-specific IR techniques for the study of opaque samples or samples with small quantities (monolayer amount) of surface species. With the development of Fourier infrared spectroscopy (FT-IR), this situation has changed. The increased sensitivity, selectivity, energy throughput, reproducibility, and the computerization of the FT-IR technique now allow the spectroscopists to probe the chemical nature of polymer surfaces routinely.
