Spectroscopic Analysis of Interfacial Adhesion in Natural Fibre Polymer Composites

The ideal substitute materials for plastic to address the issues of pollution and non-biodegradability are natural fibre reinforced composites. These are non-toxic, biodegradable, less expensive, and have potential applications in a variety of industries, including packaging, furniture, and home goods. This is because natural fibres are abundant in nature, biodegradable, and inexpensive. However, due to inadequate interaction/bonding between hydrophilic natural fibre and hydrophobic thermoplastic/thermoset matrix, its competency with thermoplastic is hampered by low mechanical qualities and other physical features. Numerous studies have been conducted with the goal of strengthening the chemical interaction between the fibre and matrix, either by roughening the surface of natural fibre or by altering resin. Spectroscopic examination, including Fourier transform infrared, Raman spectroscopy, nuclear magnetic resonance, and X-ray photoelectron spectroscopy are used to characterize the produced composites after modification of natural fiber. The strength of the composites in question is provided by the connection between functional groups of fibre and resin at the interface, which was discovered through spectral analysis of composites.
