Abstract

Polylactic acid (PLA) nanocomposites are lightweight, environmentally friendly, easy fabrication, low cost, and excellent biocompatibility. Its nanocomposites are usually made of PLA matrix filled with nano-fillers such as nanotubes (e.g., carbon nanotubes), quantum dots, nanoclays, nanofibers, graphene, and even other polymers. Compared to PLA, PLA nanocomposites can have improved electrical properties, higher thermal conductivity, dielectric constant, better thermal stability, biodegradability, and so on. Thus, PLA nanocomposites have been widely used for various sensing applications. This review discusses the common methods, such as chemical/physical modification and electrospinning, used to prepare the PLA nanocomposites. Meanwhile, recent applications of PLA nanocomposites as sensors in the field of moisture, piezo/strain, chemical/bio, thermal, and other fields are summarized in this review. The performances of each type of sensors have been highlighted in each section.

期刊介绍： Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field. The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest. Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials. Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
