Abstract
With the continuing efforts to explore alternatives to petrochemical-based polymers and the escalating demand to minimize environmental impact, bio-based polymers have gained a massive amount of attention over the last few decades. The potential uses of these bio-based polymers are varied, from household goods to high end and advanced applications. To some extent, they can solve the depletion and sustainability issues of conventional polymers. As such, this article reviews the trends and developments of bio-based polymers for the preparation of polymer electrolytes that are intended for use in electrochemical device applications. A range of bio-based polymers are presented by focusing on the source, the general method of preparation, and the properties of the polymer electrolyte system, specifically with reference to the ionic conductivity. Some major applications of bio-based polymer electrolytes are discussed. This review examines the past studies and future prospects of these materials in the polymer electrolyte field.
Highlights
Introduction to BioBased PolymersBio-based polymers are growing in importance over the past few decades due to their potential as replacements or alternatives to conventional polymers
The second type of bio-based polymer refers to polymers that are chemically synthesized from naturally-derived monomers
Similar to conventional petrochemical-based polymer electrolytes, bio-based polymers suffer from low ionic conductivity when compared to liquid electrolytes
Summary
Bio-based polymers are growing in importance over the past few decades due to their potential as replacements or alternatives to conventional polymers. They are the key feature to solve many international issues such as global warming, price fluctuations, the shortage of petroleum resources, pollution, and other economic and ecological issues. Bio-based polymers refer to a type of polymer that is produced naturally by living organisms [1]. In other words, it is called a natural polymer. The first refers to polymers directly extracted from biomass, such as starch, cellulose, chitosan, and alginates They are the most abundant and a major resource of bio-based polymers.
