In this study, we used poly L-latcide, poly DL-latcide-co-glycolide 75:25 (PLGA7525) and poly DL-latcide-co-glycolide 50:50 (PLGA5050) during citric acid inducing ammonium bicarbonate gas forming process to form porous polymer film, and rolled the porous polymer film to make nerve conduits with pores and multi-layered. Electron Spectroscopy for Chemical Analyzer and Attenuated Total Reflectance – Fourier-Transform Infrared Spectrometer were employed for determining elements' functionabilities and chemical compounds. Charge Coupled Device camera and Scanning Electron Microscope were employed for macroscopic and microscopic morphologies and structural observation. Differential Scanning Calorimetry was employed for measuring glass-transition temperature. Nano-indentation system was employed for measuring elastic modulus and hardness. Biodegradation and water absorption ratios were measured to analyze their chemical properties and SEM was employed for microscopic morphology of the tested nerve conduit.
