Ligament tears can strongly influence an individual’s daily life and ability to engage in physical activities. It is essential develop artificial scaffolds for ligament repairs order effectively restore damaged ligaments. In this experiment, the objective was evaluate fibrous membranes as repair. These were created through electrospinning using piezoelectric polyvinylidene fluoride (PVDF) composites, which contained 1 wt.% 3 of copper-impregnated nanohydroxyapatite (Cu-nHA). The proposed electrospun membrane would feature aligned fiber structure achieved high-speed roller stretching, mimics properties biomimetic Nanoparticles Cu-nHA had been composited into PVDF enhance pirzoelectric β-phase crystallines. study assessed physicochemical properties, antibacterial activity, biocompatibility vitro. A microstructure analysis revealed that composite exhibited a bionic with fibers resembling human performance experimental group containing significantly improved 25.02 ± 0.68 V/g·m−2 compared pure at 18.98 1.18 V/g·m−2. Further enhancement by 31.8% manipulating semicrystalline structures. Antibacterial cytotoxicity tests showed inherited nanoparticles without causing cytotoxic reactions. Tensile membrane’s flexibility strain adequate use particular, mechanical two groups enhanced those group. favorable flexible are highly beneficial tissue regeneration. This successfully developed PVDF/Cu-nHA biocompatible, unidirectional potential applications repair scaffolds.
