A Review on Potential Applications of PLA Nanofibers

Abstract

In recent years, bio-based polymeric materials have attracted increased attention due to their renewability and environmental friendliness. Polylactic acid (PLA), a biodegradable bio polyester, has emerged as the dominant polymer in industrial applications and is often referred to as the “polymer of the 21st century.” It possesses biocompatibility, biodegradability, and a biobased nature, making it unique among polymers synthesized on a large scale. PLA, a non-toxic linear aliphatic thermoplastic polyester, exhibits favorable thermomechanical properties and finds widespread use in various fields, including biomedical applications, the food industry, air and water filtration, and sensors. Nanofibers are most attractive materials in the scientific world due to their enormous applications in various fields. Electrospun membranes have been showed high porosity and high specific surface, as well as tunable mechanical properties and topological features. This review focuses on recent developments, current findings, and emerging trends in the field of PLA-based nanofibers, highlighting advancements in PLA properties and providing detailed insights into the preparation and diverse applications of nanofibers based on PLA.
