In consideration of environmental concerns and unsustainable fossil resource, biobased polymer is being paid great attention. Comparing with fossil polymers, all biobased polymers are renewable, and most of them are biodegradable and have less greenhouse gas emissions. Nevertheless, recent years witnessed the extensive applications of biobased polymers for value-added advanced functional materials, such as shape memory and biomedical and conductive materials. This special issue aims to create a multidisciplinary forum of discussion on the most recent advances in synthesis, characterization, application, and sustainability assessment of biobased polymers, providing a profound and instructional outlook for future studies.

We are pleased to launch this special issue and invite researchers worldwide to contribute their high quality research papers, which are original and reviews. The contribution may include both theoretical and experimental results that cover aspects of synthesis, characterization, application, and sustainability assessment of biobased polymers. The research topics, which are beyond the mentioned aspects but regard biobased polymers, are more than welcomed.

Potential topics include but are not limited to the following:

• Synthesis, modification, and characterization of biobased polymers
• New processes for the preparation of biobased monomers from natural feedstock
• The application of biobased polymers in biomedicine and tissue engineering
• The application of biobased polymers in multiresponsive materials
• The application of biobased polymers in nanotechnology and in advanced 3D printing
• The durability of biobased polymers
• The degradation of biobased polymers
• The life-cycle assessment analysis (LCA) on biobased polymers
