Preparation and Performance Research of the PBC / PLA Biodegradable Film

Abstract

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) .

Influence of aliphatic polycarbonate middle block on mechanical and microstructural behaviour of triblock copolymers based on poly(l‐lactide) and polycarbonate

“…Also, aliphatic carbonates with linear chains exhibit a flexible nature with glass transition temperature ( T g ) below room temperature. For example, poly(butylene carbonate) has T g of ca −36 °C with excellent impact strength and has already been used with PLA to improve its toughness . Hence, aliphatic polycarbonates have the potential to enhance the toughness of any brittle polymer when they are used together.…”
