Fourier transform infrared spectroscopy: A power full method for creating fingerprint of molecules of nanomaterials

Abstract

The Fourier transform infrared spectroscopy (FTIR) technique is a very useful tool to determine bonding mechanisms in solids. This technique is essential for understanding the properties and behaviors of nanomaterials, which have applications across various fields including medicine, electronics, and environmental science. The FTIR spectra gives complete profile of specimen/sample thus showcasing a distinct molecular fingerprint that can be used to scan, screen and investigate the performance of samples for many different components. By analyzing FTIR Spectroscopy data, this paper aims to study the chemical composition, molecular interactions within nanomaterials, polymer matrices or other materials like membranes, composites, characterizing covalent bonding information and identify a molecule through the combination of all of the functional groups. For industrial purpose, FTIR spectroscopy is also used as a quality control measure wherein it provides the complete spectra of the product or raw material that an industry uses. The change in the composition of the material is denoted by studying the variations in the pattern of absorption bands/ spectra so obtained. Thus, FTIR can be significant in identifying and origin of any problem in any material typically by microanalysis. This paper presents the methodology, interpretation of results, providing insights into the efficiency of FTIR as a characterization tool and the importance of FTIR spectroscopy technique for creating the fingerprint of molecules of nanomaterials, and polymer matrices or other materials like membranes, composites. This review paper will be helpful for the beginners in the field of chemical application of nanomaterials and spectroscopy.
