Technical Abstract: Polylactic acid (PLA) is one of the most widely used biodegradable polyesters. PLA is blended with various forest and agricultural-based natural polymers for the development of biobased materials with improved water-resistance. PLA is also blended with synthetic polymers for the development of biocompatible and biodegradable blends for use in medical and other fields. Compatibility is one of the critical factors affecting the successful commercialization of PLA-based blends. One of the factors affecting compatibility is interfacial tension. In this work, the various factors affecting interfacial adhesion between PLA and polystyrene are investigated using an asymmetric double cantilever beam fracture test. The results are used to assess compatibility and interfacial tension in PLA-base blends.
