PBS-DLS-PEG copolymers, comprising PBS as hard segment and DLS and PEG as soft segments, have been synthesized using 2-step polycondensation as described in previous work . Extensive investigations into their chemical, thermal, mechanical, and biological properties have been documented in previous articles ,( ), . Notably, these copolymers have demonstrated remarkable potential for biomedical applications, showcasing tailored mechanical properties, a favorable biodegradability profile, and excellent cytotoxicity. Moreover, these copolymers exhibit suitability for both melt and solution processing techniques, such as electrospinning and 3D printing. Based on these findings, the PBS-DLS copolymer comprising 70 wt.% of hard segments and 30 wt.% of soft segments, along with its modification with 5 wt.% PEG, were chosen for this study due to their exceptional processibility, mechanical properties, and biodegradability profile.
