Analysis of Composite Films using FTIR
Composite films are mainly used for the packaging of food where many requirements have to be met in order to preserve taste and freshness of the product. Packaging needs to prevent water vapor from entering or leaving the packaging. FTIR Microscopy allows for the identification of different materials in composite films and can determine their distributions. Furthermore, defects in polymer matrix can also be localized and identified.
Getting accurate IR spectra on monolayer of molecules
April 18th 2024Creating uniform and repeatable monolayers is incredibly important for both scientific pursuits as well as the manufacturing of products in semiconductor, biotechnology, and. other industries. However, measuring monolayers and functionalized surfaces directly is. difficult, and many rely on a variety of characterization techniques that when used together can provide some degree of confidence. By combining non-contact atomic force microscopy (AFM) and IR spectroscopy, IR PiFM provides sensitive and accurate analysis of sub-monolayer of molecules without the concern of tip-sample cross contamination. Dr. Sung Park, Molecular Vista, joined Spectroscopy to provide insights on how IR PiFM can acquire IR signature of monolayer films due to its unique implementation.
