Preparation and performance research of the PBC/PLA biodegradable film

This paper mainly describes a novel biodegradable material poly(butylene carbonate) (PBC) to blending toughing modification for polylactic acid (PLA), and prepared the PBC/PLA biodegradable film) of improved toughness. To research the effect of thermol performance and mechanical properties (tensile strength and breaking elongation rate) through Fourier transform infrared spectroscopy(FTIR), differential thermal scanning calorimetry analysis (DSC) and tensile testing to expound different ratio of PBC and additive plasticizer, (lubricant and chain extender).
