Progress on preparation methods and performance regulation of isosorbide-based polycarbonates
Bisphenol A-based polycarbonate(BPA-PC)has limited applications in food packaging and other fields due to the non-renewable and estrogenic effects of bisphenol A.In recent years,isosorbide(IS),a non-toxic and harmless bio-based renewable monomer,is regarded the most promising key raw material for replacing bisphenol A in the synthesis of polycarbonates.And the isosorbide-based polycarbonate(IS-PC)has shown good application prospects in packaging,automobiles,electronics,biomedicine and other fields due to its non-toxicity,excellent optical properties,scratch resistance,thermal stability,biodegradability and biocompatibility.Herein,the preparation methods and performance regulation of IS-PC were reviewed.The research status of IS-PC synthesized from melt transesterification was then introduced in detail.Finally,the regulation methods on the performance of IS-PC were summarized,and the future research directions were prospected.
