Abstract Tissue-engineering was important and popular which combine medical applications and engineering materials knowledge, just like decellularization techniques were employed to remove the cellular components from porcine elastic cartilages, leaving a native decellularized extracellular matrix(dECM) composition and architecture integrity of largely insoluble collagen, elastin, and tightly bound glycosaminoglycans. Particularly, an extraction process of supercritical carbon dioxide(ScCO2) was used to remove cellular components from porcine skins. The porcine skins must remove lipids and other impurities by using ScCO2 procedure. In this study, a series of new composite membranes with decellularized scaffolds could be designed and obtained from porcine skin tissue by using supercritical carbon dioxide fluid technology. The retain decellularized extracellular matrix (dECM) and integrity scaffold-structure could be observed in the new composite membranes. This work provides a simple and time-saving method process for preparation of biomedical composite membranes with dECM scaffolds for biomimetic bioinks, which were further characterized by Fourier transform infrared spectroscopy (FTIR), thermo-gravimetric analysis (TGA), and scanning electron microscope(SEM).
