Abstract
|
The advent of polymer-based dielectrics marked a significant breakthrough in dielectric materials.
However, despite their many advantages, they pose serious environmental threats. Therefore, in recent
years, there has been growing interest in bio-based polymers as a sustainable alternative to traditional
petroleum-based polymers. Their renewable nature and reduced environmental impact can fulfil the
rising demand for eco-friendly substitutes. Beyond their ecological benefits, bio-based polymers also
possess distinctive electrical properties that make them extremely attractive in a variety of applications.
Considering these, herein, we present recent advancements in bio-based dielectric polymers and
nanocomposites. First, the fundamental concepts of dielectric and polymer-based dielectric materials
are covered. Then, we will delve into the discussion of recent advancements in the dielectric properties
and thermal stability of bio-based polymers, including polylactic acid, polyhydroxyalkanoates,
polybutylene succinate, starch, cellulose, chitosan, chitins, and alginates, and their nanocomposites.
Other novel bio-based dielectric polymers and their distinct dielectric characteristics have also been
pointed out. In an additional section, the piezoelectric properties of these polymers and their recent
biomedical applications have been highlighted and discussed thoroughly. In conclusion, this paper
thoroughly discusses the recent advances in bio-based dielectric polymers and their potential to
revolutionize the biomedical industry while cultivating a more sustainable and greener future.
