“…Various synthesis strategies (e.g., chemoenzymatic methods, enzymatic ring opening polymerization, radical ring opening polymerization, coordinative ring opening polymerization, anionic ring opening polymerization, photo-initiated ring opening polymerization, and so on) have been widely employed in the preparation of a diverse mixture of biodegradable polymer blends with different compositions, phases, and morphologies [7,[9][10][11][12][13][14][15][16][17]. Among biodegradable polymeric blends, more recently, poly(hydroxybutyrate-valerate) (PHBV) and poly(caprolactone) (PCL) have garnered extensive interest concerning a wide range of technological applications, thereby providing opportunities to develop emergent technologies in the future [18][19][20][21][22].…”

In this study, we investigated the influence of γ-irradiation (0, 50, and 100 kGy) doses on the chemical and mechanical properties of biodegradable poly(hydroxybutyrate-valerate)/poly(caprolactone) (PHBV/PCL) polymer blends rich in low-molar-mass PCL, which were prepared using a co-rotating twin-screw extruder. In parallel, the density functional theory (DFT) and the time-dependent DFT (TD-DFT) methods were used together with a model containing four monomer units to provide an insight into the electronic structure, chemical bonds, and spectroscopic (such as Nuclear Magnetic Resonance (NMR) and Ultraviolet-visible (UV-vis)) properties of PHBV and PCL blend phases, which are critical for predicting and designing new materials with desired properties. We found that an increase in γ-irradiation doses caused splitting instead of crosslinks in the polymer chains, which led to evident deformation and an increase in tensile strength at break of 2.0 to 5.7 MPa for the PHBV/PCL blend. Further, this led to a decrease in crystallinity and proved the occurrence of a more favorable interaction between the blend phases.

“…In the field of medical implants, biodegradable materials have garnered significant attention in recent years. Biodegradable surgical sutures, which were made by polydioxanone, polylactic, and polyglycolic acid, have been applied in clinical practice and effectively reduce the side effects caused by permanent materials [ [7] , [8] , [9] ]. However, the mechanical properties of these polymers are too low to provide adequate mechanical support.…”

Mechanically robust and tough polymeric materials are in high demand for applications ranging from flexible electronics to aerospace. However, achieving both high toughness and strength in polymers remains a significant challenge due to their inherently contradictory nature. Here, a universal strategy for enhancing the toughness and strength of polymer blends using ligand‐modulated metal–organic framework (MOF) nanoparticles is presented, which are engineered to have adjustable hydrophilicity and lipophilicity by varying the types and ratios of ligands. Molecular dynamics (MD) simulations demonstrate that these nanoparticles can effectively regulate the interfaces between chemically distinct polymers based on their amphiphilicity. Remarkably, a mere 0.1 wt.% of MOF nanoparticles with optimized amphiphilicity (ML‐MOF(5:5)) delivered ≈3.4‐ and ≈34.1‐fold increase in strength and toughness of poly (lactic acid) (PLA)/poly (butylene succinate) (PBS) blend, respectively. Moreover, these amphiphilicity‐tailorable MOF nanoparticles universally enhance the mechanical properties of various polymer blends, such as polypropylene (PP)/polyethylene (PE), PP/polystyrene (PS), PLA/poly (butylene adipate‐co‐terephthalate) (PBAT), and PLA/polycaprolactone (PCL)/PBS. This simple universal method offers significant potential for strengthening and toughening various polymer blends.
