Polymer nanocomposites can be defined as materials in which nanoscopic inorganic particles, in at least one dimension, are dispersed in an organic polymer matrix to improve its performance properties. Polymer nanocomposites represent a new alternative to conventional filled polymers. Because of their size, the filler dispersion that nanocomposites exhibit markedly improves their properties when compared to pure polymers or their traditional composites. These properties include increased tensile strength and thermal stability as well as decreased flammability.

This special issue focuses on the synthesis, characterization, electrical properties, and applications of polymer nanocomposites such as energy storage (lithium-ion batteries and fuel cells), water treatment, and biosensors. We invite all researchers working in this area to submit their original research as well as review articles to this special issue.

Potential topics include but are not limited to the following:

• Synthesis and characterization of polymer nanocomposites
• The structure and electrical properties of polymer nanocomposites
• The application of polymer nanocomposites in lithium ion batteries
• The application of polymer nanocomposites in fuel cells
• The application of polymer nanocomposites in water treatments and biosensors
