Clay–conducting polymer nanocomposites (CPNs) have gained attention as versatile materials that are easy to produce and useful across a wide range of technologies. Combinations of montmorillonite (MMT) clay with electronically conducting polymers (ECPs) such as polyaniline (PANI), polypyrrole (PPY), and poly(ethylenedioxythiophene) (PEDOT) stand out. These materials combine mechanical strength with the ability to conduct electricity, making them multifunctional. This review explores the development of MMT–ECP nanocomposites from early electroactive films to their growing roles in sustainable energy, industrial waste management, environmental cleanup, wastewater treatment, biomedical devices, and smart packaging. Different methods used to make these materials, such as in situ oxidative polymerization, solution intercalation, and electrochemical deposition are discussed. Each method influences how well the clay layers separate, how the polymer spreads, and how strongly the components bond together. Additionally, the effect of the structure of these nanocomposites on their performance is assessed, using tools such as spectroscopy, microscopy, electrochemistry, and thermal analysis. Their applications in areas including supercapacitors, solid-state batteries, electromagnetic interference (EMI) shielding, chemical sensors, and water purification are reviewed, with special attention to eco-friendly processes and systems that can integrate with biological environments. The review emphasizes strategies aimed at meeting performance needs without compromising sustainability. Cross-sectoral relevance is highlighted, spanning well-established areas such as energy storage alongside emerging fields such as biomedical systems and smart packaging. By bringing together insights from materials science, nanotechnology, and electrochemistry, these nanocomposites offer a promising foundation for building the green technologies of the future.
