In the current study, a phase inversion scheme was employed to fabricate hydroxyapatite (HA)/polysulfone (PSF)-based asymmetric membranes using a film applicator with water as a solvent and nonsolvent exchanging medium. Fourier Transform Infrared (FTIR) and X-ray diffraction (XRD) spectroscopic studies were conducted to confirm the bonding chemistry and purity of filler. The inherent thick nature of PSF generated sponge-like shape while the instantaneous demixing process produced finger-like pore networks in HA/PSF-based asymmetric membranes as exhibited by scanning electron microscope (SEM) micrographs.

FTIR and Raman spectroscopic analysis was done to obtain information about the bonding chemistry of the obtained filler. The intermolecular interaction that existed between dahllite/hydroxyapatite/collagen filler and pristine PSf was confirmed by Raman spectroscopic study.

- The study demonstrates the creation of a CO3Ap/HAP additive from chicken bones through high-temperature calcination, which shows strong interactions with the polysulfone polymer.
- Electron analyses revealed the structure and bonding of the composite membranes, highlighted by distinct finger-like patterns in the CO3Ap/HAP/PSF blend compared to a sponge-like structure in pure PSF.
- The membranes exhibited enhanced hydrophilicity, increased water permeability, and significant resistance to fouling, with in vitro tests indicating good biocompatibility and anticoagulation properties.
