What is it about?
Polymeric composite (PC) materials are multifarious materials widely used in almost all industries due to their fascinating properties of being flexible, light weight, durable, cost effective and ease of mass fabrication in variety of shapes and sizes. Further the thermo physical properties of these polymeric materials can be further enhanced by addition of appropriate amount of organic or inorganic filler. Their high refractive index renders them to be used as components in manufacturing of opto-electronic devices and hence certain opto electronic parameters can be tailor made by insertion of appropriate filler in the host polymer. PMMA is one such versatile polymer with interesting optical properties which can be further tuned up with filler enforcement for desired application. This review deals with such organic and inorganic filler doped PMMA composites with enhanced optical properties. Initially, the authors throw light on general physical and chemical properties of PMMA and its suitability to incorporate various fillers and the varied approaches of PMMA filler interactions. The review addresses briefly the various techniques of synthesis and optical characterisation of these PMMA based PC Further it attempts to summarize the underlying theories and concepts that construe the correlation between structure and optical parameters. The introduction of filler to bring a change in optical behaviour as desired is challenging one. Hence authors have included not only the present state of art of these materials and the challenges thrown but also how the researchers are to mitigate them in future.

Why is it important?
Band gap engineering and optical characterization of filler-reinforced PMMA thin films involve the modification and study of the electronic band structure and optical properties of these nanocomposite materials. This is an essential aspect of tailoring the material for specific applications in areas like photonics, optoelectronics, and sensors. To achieve desired optical properties in PMMA nanocomposite films, it is crucial to carefully select the type and concentration of nanoparticles, optimize dispersion techniques, and control film thickness
Perspectives
As the main author of the article "Bandgap Engineering and Optical Characterizations of Filler Reinforced PMMA," I explore the transformative impact of integrating fillers into PMMA (Polymethyl Methacrylate) to manipulate its electronic and optical properties. By engineering the bandgap, we aim to enhance its potential for applications in photonic and optoelectronic devices. Detailed optical characterizations provide insights into how filler materials influence the absorption, transmittance, and overall performance of PMMA, contributing to the development of advanced polymer-based materials with tailored functionalities.
