Nevertheless, the dispersion of Fe<sub>3</sub>O<sub>4</sub> in PVDF matrix was a challenge. Herein, Fe<sub>3</sub>O<sub>4</sub> nanoparticles were in situ grown on the surface of graphene oxide (GO) nanosheets (GO@Fe<sub>3</sub>O<sub>4</sub>) to inhibit their aggregation in PVDF scaffold. Specifically, the enormous specific surface area of GO supplied abundant space for the uniform nucleation and growth of Fe<sub>3</sub>O<sub>4</sub> nanoparticles. In turn, Fe<sub>3</sub>O<sub>4</sub> would act as steric hindrance to suppress the stacking of GO nanosheets. Morphological analysis indicated that GO@Fe<sub>3</sub>O<sub>4</sub> was uniformly distributed in PVDF matrix. Particularly, X-ray photoelectron spectroscopy and polarization microscope measurements revealed that oxygen-containing functional groups on GO forced the orientation arrangement of -CF<sub>2</sub> groups in PVDF through hydrogen bonding, forming piezoelectric β phase. As a result, the electrical output of the scaffold was significantly enhanced, with an output current of 57 nA and voltage of 8.5 V. Cell culture demonstrated that the enhanced electrical stimulation and synergistic magnetic stimulation effectively promoted the proliferation and differentiation of cells.

The introduction of co-solvents can enhance the mutual solubility between aqueous and organic phases, which promotes the PIP diffusion rate and contributes to high-performance NF membranes characterized by smaller pore sizes. Notably, membranes prepared with DMAc demonstrated enhanced retention of divalent ions (MgCl<sub>2</sub>: from 41 % to 83.4 %) and maintained high permeability (46.6Lm<sup>−2</sup> h<sup>−1</sup> at 0.3 MPa), whereas excessive co-solvents could damage the performance. Additionally, Molecular dynamics (MD) simulations show that the co-solvent regulates PIP diffusion rate with its diffusion rate by hydrogen bonding with the PIP molecules and moving together with PIP. Significant variations in the PIP diffusion rate resulted in a wrinkled morphology on the membrane surface.

The DP-MD approach demonstrates superior concordance with experimental observations compared to the RIA-MD and MC/BCA methods, as evidenced by reduced normalized root mean square error metrics.
