Abstract
In recent years, the interest of researchers in developing materials that can solve the problems of energy scarcity and environmental pollution has led to a special focus on nanocellulose and carbon nanotube-based composites. Nanocellulose has outstanding characteristics that promote highly ordered structures that are renewable and biodegradable. Carbon nanotubes, in turn, have high surface area, strength and electrical functionality. Their combined use holds promise for the development of composites with unique properties applicable in a variety of applications. However, despite the research conducted, questions remain unresolved regarding the technological aspects of production and specific applications of nanocellulose and carbon nanotubes. This review presents recent advances in the field of multifunctional hybrid nanocellulose and carbon nanotube-based nanocomposites, with a focus on their role in addressing environmental and energy challenges. The paper discusses the characteristics and advantages of the components of the composites, methods for their synthesis, as well as potential problems and possible directions for further research. Particular emphasis is placed on improving the interactions between the components, reducing the cost of production, and extending the scope of applications by integrating additional nanomaterials.
