Lignocellulose:a green platform for synthesizing renewable monomers and polymers
High-value utilization of lignocellulose offers a promising pathway to gradually run away from fossil fuel dependence,which is the key for economic viability of the lignocellulosic biorefinery industry.In this review,we first described the structure and properties of lignocellulose,which would be helpful in understanding the deconstruction of lignocellulose to generate renewable polymeric monomers.As multifunctional properties of lignocellulose could be utilized in the development of various bio-based polymers,we then presented the sources and future trends of value-added renewable sugar-based compounds and lignin-based compounds from the three major components of lignocellulose,and provided a systematic summary of their polymer development.In addition,we outlined the role of bio-based aliphatic polyesters in toughening poly(lactic acid)(PLA)materials,including the property modifications of the derived polyesters through changing the composition,content and grafting method of the monomers.Finally,we highlighted that lignocellulose-derived polyester research could be potentially integrated across disciplines,with a list of new strategies and trends for the development of bio-based materials at the process,application,and economic levels.
