Recent developments in lipase-catalyzed synthesis of polymeric materials

Abstract In the past three years, enzymatic polymerization has dramatically developed and provided many successful examples in the construction of functional polymeric materials. In this review, the lipase-catalyzed synthesis of polymeric materials is systematically summarized, focusing on the synthesis of complex and well-defined polyesters. Exploration of novel biocatalysts and reaction media is described, with particular emphasis on the enzymes obtained via immobilization or protein engineering strategies, green solvents and reactors. Enzymatic polyester synthesis is then discussed with regard to the different reaction types, including ring-opening polymerization, polycondensation, combination of ring-opening polymerization with polycondensation, and chemoenzymatic polymerization. Using enzymatic polymerization, many polymeric materials with tailor-made structures and properties have been successfully designed and synthesized. Finally, recent developments in catalytic kinetics and mechanistic studies through the use of spectroscopy, mathematics and computer techniques are introduced. Overall, the review demonstrates that lipase-catalyzed synthesis of polymeric materials could be a promising platform for green polymer chemistry, and will be potential to produce biodegradable and biocompatible polymers.
