Studying the degradation of polyhydroxybutyrate-co-valerate during processing with clay-based nanofillers
(Wiley, 2009)
Polyhydroxybutyrate-co-valerate (PHBV) is attracting interest as a new material for packaging applications and nanoparticulate layered silicates are being increasingly explored as a way to improve PHBV film properties. In ...
Development and characterization of unmodified kaolinite/EVOH nanocomposites by melt compounding
(Elsevier, 2016-10)
Nanocomposites of unmodified kaolinite (Kaol)/ethylene-vinyl alcohol copolymer (EVOH) with different Kaol contents have been obtained by a two-step process: melt blending in an internal mixer and film processing by ...
Insights into the potential effects of released engineered nanomaterials from polymer nanocomposites: environmental issues and future activities for risk assessment and management
(Springer, 2021-04-01)
The use, production, and disposal of engineered nanomaterials (ENMs) raise concerns about their environmental impact at all stages of the life cycle, considering that nanostructured materials can be released to the air, ...
Comparative study of nanocomposites of polyolefin compatibilizers containing kaolinite and montmorillonite organoclays
(Wiley, 2010-02)
This work studied the morphology and physical properties of nanocomposites of different ethylene copolymers and functionalized polyethylenes with two different types of organoclays, to assess the potential application of ...
Influence of crystallinity on the fracture toughness of poly(lactic acid)/montmorillonite nanocomposites prepared by twin-screw extrusion.
(© 2010 Wiley Periodicals, 2011-04)
The aim of this work was to study the effect of crystallinity degree on the thermal, mechanical, and fracture properties of poly(lactic acid)/organomodified montmorillonite (PLA/OMMT) nanocomposites. Samples with two ...
Aplicación de la mecánica de la fractura post-cedencia a polímeros
(Universidad Simón Bolívar, 2010)
The Essential Work of Fracture (EWF) technique has been used for the ductile materials characterization, where
yielding phenomenon occurs before crack propagation. The EWF method characterizes the post-yielding ...
