Investigation of physical and mechanical properties of polyurethane-polycaprolactone porous membrane for tissue engineering

The flat-sheet porous membrane was prepared with the blend of polyurethane (PU) and polycaprolactone (PCL) by the phase inversion method. The morphology structure of PU-PCL membrane was studied by scanning electron microscopy (SEM). Also fourier transform infrared (FTIR), differential scanningcalorimetry (DSC) and thermo-gravimetric (TG) were used to investigate chemical composition, phase change behavior and thermal stability of membrane, respectively. The effect of concentration and different ratios of biodegradable blend polymer on physical and mechanical properties were reported
