Optical characterization of polyaniline nanocellulose composite films for electronic applications

Abstract

Nanomaterials' one-of-a-kind characteristics and versatility have piqued a lot of interest in their incorporation into composite films for use in electronics. The optical characterisation of composite films made of polyaniline and nanocellulose is the main focus of this work, which aims to explore the materials' versatility and their applications in electrical devices. Combining nanocellulose, which is sourced from sustainable resources, with polyaniline, a conductive polymer with outstanding electrical characteristics, produces composite films. One easy and scalable step in the production process is the creation of polyaniline nanoparticles, which are then dispersed inside a nanocellulose matrix. Spectroscopic techniques, such as UV-Visible spectroscopy, are used to carefully study the optical characteristics of the composite films. The objective of the investigation is to clarify how the optical transparency and absorbance properties of the nanocellulose composite films are affected by the addition of polyaniline. The research also delves into how different concentrations of polyaniline affect the films' optical performance. Within the framework of their optical characteristics, the possible uses of these composite films in electronic devices including sensors, flexible displays, and optoelectronic devices are addressed. Insights into the design and optimization of materials for electronic applications are gained from this study, which adds to our basic knowledge of the optical behaviour of polyaniline nanocellulose composite films. Composite films made of nanocellulose are very attractive to new technology because of their low environmental impact and long lifespan, which might lead to more efficient and less harmful electrical gadgets.
