Toughening of Polylactide PLA by Blending with Elastomeric Materials



Toughening of polylactide by blending with various elastomeric materials
Meyva, Yelda; Kaynak, Cevdet; Department of Polymer Science and Technology (2014)
The purpose of the first part of this thesis was to investigate influences of three different ethylene copolymers on the toughness and other properties of very brittle biopolymer PLA (polylactide). For this aim, PLA was melt blended by twin-screw extruder with various amounts of ethylene vinyl acetate (EVA), ethylene methyl acrylate (EMA) and ethylene-n-butyl acrylate-glycidyl methacrylate (EBA-GMA). SEM and DSC analyses indicated that these ethylene copolymers were thermodynamically immiscible with phase s...
Toughening of Polylactide by Bio-Based and Petroleum-Based Thermoplastic Elastomers
Meyva, Y.; Kaynak, Cevdet (2015-11-01)
The purpose of this study was to improve toughness of inherently very brittle polylactide (PLA) without sacrificing strength and thermal properties, so that biopolymer PLA could be used in engineering applications. For this purpose, PLA was blended with various amounts of two different thermoplastic elastomers; TPU (petroleum-based thermoplastic polyurethane) and TPE (bio-based thermoplastic polyester). Melt blending and specimen shaping were achieved by using a twin-screw extruder and injection molder, res...

Softening due to Grain Boundary Cavity Formation and its Competition with Hardening in Helium Implanted Nanocrystalline Tungsten
Cunningham, W. Streit; Gentile, Jonathan M.; El-Atwani, Osman; Taylor, Chase N.; Maloy, Stuart A.; Trelewicz, Jason R.; Efe, Mert (Springer Science and Business Media LLC, 2018-2-13)
The unique ability of grain boundaries to act as effective sinks for radiation damage plays a significant role in nanocrystalline materials due to their large interfacial area per unit volume. Leveraging this mechanism in the design of tungsten as a plasma-facing material provides a potential pathway for enhancing its radiation tolerance under fusion-relevant conditions. In this study, we explore the impact of defect microstructures on the mechanical behavior of helium ion implanted nanocrystalline tungsten...
