Poly(glycerol sebacate) (PGS) and its derivatives have been developed and used for various biomedical applications over the past two decades. Several publications have reviewed the development of PGS from different perspectives, typically focusing on the biofabrication techniques and intended biomedical applications of PGS. However, a comprehensive review of the progress in the research on PGS and its derivatives over the past two decades, in terms of material design, synthesis, and properties have not been conducted. Herein, we review the design and preparation of PGS using different synthesis processes, ranging from the traditional heat curing method to various novel synthesis approaches, before systematically exploring the development of novel PGS derivatives prepared by functional groups modification or (and) hybridizing with other substances. Moreover, a statistical analysis of related publications is presented to quantify the progress in the research on PGS and its derivatives from different perspectives and identify any trends. We expect that this review and the design principles of PGS-based materials summarized herein will inform and promote the further development and optimization of PGS and its derivatives for biomedical applications.

Metal-organic frameworks (MOFs) have drawn a lot of interest as prospective starting points for highly effective electromagnetic wave (EMW) absorbers. However, the inevitable shrinkage and probable densification that occur during pyrolysis significantly reduce the microwave-loss capacity. A dual-layer MOF, ZIF-8@ZIF-67, is created and effectively decorated on graphene sheets as a solution to this problem. The shrinkage and densification were then suppressed by the subsequent pulverization effect between the two MOFs. Due to suitable compositions and specialized microstructures, G/Co@C exhibits excellent impedance matching and dissipates EMW by combining magnetic and dielectric loss. The maximum reflection loss of G/Co@C-7/paraffin is -55.0 dB at 5.8 GHz with just 7% filler. Therefore, the preparation of high-efficiency MOF-derived microwave absorbers by the pulverization effect is demonstrated to be an efficient strategy.
