DOE National Lab Develops Supertough Bioplastic

Researchers at Oak Ridge National Laboratory (ORNL) announced the development of a method to create a supertough renewable plastic with improved manufacturability.  The method involved the addition of a small amount of silanes to polylactic acid (PLA), a bioplastic commonly used in packaging, textiles, biomedical implants, and 3D printing.  The new bioplastic demonstrated improved tensile strain and tensile toughness, without a loss in tensile strength and modulus.  According to ORNL’s Soydan Ozcan, the new method offers a fast, scalable route to increasing PLA toughness, which will broaden the use of PLA.
