Petroleum-derived polymers have been popular for decades due to their interesting attributes, such as their lightness and strong mechanical properties, which makes them extremely useful for a wide range of application areas, such as packaging, transportation, household, construction, and aerospace. Despite this, in recent years there has been a strong research focus on a new class of polymers, namely, biopolymers (e.g., polysaccharides and proteins) and biobased polymers (e.g., polylactide and bio-polyesters). Much effort has already been devoted to replacing traditional oil-based polymers with these biopolymers and biobased polymers. In this regard, a major reason is that the heavy use of non-degradable synthetic polymers for decades has negatively influenced people’s health and caused irreversible damage to the environment. Given this, our human society urgently needs sustainable solutions to address the issues induced by the traditional ‘produce–use–discard’ practice. The other motivation to embrace biopolymers and biobased polymers is associated with their unique properties and appealing functionality. In particular, these polymers present enormous potential for environmental and biomedical applications due to their biodegradability, nontoxicity, chemical versatility and reactivity, biocompatibility, and bioresorbability.
Despite their enormous potential, challenges remain for the application of biopolymers and biobased polymers. Engineering difficulties may exist for these ‘green’ polymers that prevent them from being cost-effectively processed into materials with desired forms and structures. Besides this, the resultant materials from biopolymers and biobased polymers may exhibit unsatisfactory properties (e.g., mechanical) for certain applications. Numerous studies have therefore been undertaken to enhance the competitiveness of biopolymers and biobased polymers by various means such as molecular design, chemical modification, material hybridisation, and process innovation. This Topical Collection is concerned with the chemistry and engineering aspects of different biopolymers (e.g., cellulose, chitosan/chitin, starch, proteins, and pectins) and biobased polymers (e.g., polylactide and polyhydroxyalkanoates). The collection provides an opportunity to discuss the trends in the field of biopolymers and biobased polymers, addresses the fundamental understanding of the structure–processing–property relationship for materials design, and highlights new, advanced, and functional materials developed from these sustainable polymers for diverse and emerging applications.
