“…Melt blending: Melt blending is a technique commonly employed for thermoplastic biopolymers. It involves melting the biopolymer and adding nanofillers, followed by mixing and solidification to obtain a homogeneous nanocomposite material ( Figure 5 a) [ 148 ]. Melt blending is relatively simple and scalable, making it suitable for the large-scale production of biopolymeric nanocomposites.…”

This review article focuses on the potential of biopolymer-based nanocomposites incorporating nanoparticles, graphene oxide (GO), carbon nanotubes (CNTs), and nanoclays in adsorption and membrane filtration processes for water treatment. The aim is to explore the effectiveness of these innovative materials in addressing water scarcity and contamination issues. The review highlights the exceptional adsorption capacities and improved membrane performance offered by chitosan, GO, and CNTs, which make them effective in removing heavy metals, organic pollutants, and emerging contaminants from water. It also emphasizes the high surface area and ion exchange capacity of nanoclays, enabling the removal of heavy metals, organic contaminants, and dyes. Integrating magnetic (Fe2O4) adsorbents and membrane filtration technologies is highlighted to enhance adsorption and separation efficiency. The limitations and challenges associated are also discussed. The review concludes by emphasizing the importance of collaboration with industry stakeholders in advancing biopolymer-based nanocomposites for sustainable and comprehensive water treatment solutions.

“…[116] One significant challenge lies in achieving a homogeneous dispersion of Gr within the polymer matrix due to the π-π stacking in layers and weak van der Waals (vdW) interactions with the polymer matrix. [117] Furthermore, due to its high surface energy and tendency to agglomerate, ensuring uniform distribution can be challenging, potentially leading to regions of reduced mechanical properties in the composite. [118,119] Additionally, Gr sheets tend to form restacking structures, diminishing their effective surface area and, consequently, limiting their reinforcing potential.…”

The expansion of nanofiller‐based polymers has been rapidly increasing in contemporary society due to their wide range of applications owing to their diverse physicochemical characteristics. This review focuses on a polymer nanocomposite in which graphene is incorporated as a nanofiller and polyurethane is used as a polymer. As polyurethane is well known for its shape memory behaviour and the reinforcement of graphene‐based nanomaterial sparks the physicochemical properties of the fabricated nanocomposites which makes it more adaptable and useful for a wide array of applications. The review provides insights into the recent synthesis approaches to the fabrication of graphene‐based polyurethane nanocomposites. Further, efforts were also made to cover the recent studies done on the use of these nanocomposites as an advanced shape memory material. Rather than merely serving as descriptive content, this article is intended to serve as a comprehensive guide for researchers seeking to harness the potential of graphene‐based nanomaterial reinforcement in polyurethane for high‐performance applications. By providing a detailed overview of the latest research in this domain, the review aims to propel the development of novel and sophisticated materials, unlocking new horizons in smart shape memory technologies.
