Mechanisms of Directional Polymer Crystallization
(American Physical Society, 2020-07-21)
Zone annealing, a directional crystallization technique originally used for the purification of semiconductors, is applied here to crystalline polymers. Tight control over the final lamellar orientation and thickness of ...
Cellulose as an Inert Scaffold in Plasmon-Assisted Photoregeneration of Cofactor Molecules
(American Chemical Society, 2020-04-29)
Plasmonic nanoparticles exhibit excellent light-harvesting properties in the visible spectral range, which makes them a convenient material for the conversion of light into useful chemical fuel. However, the need for using ...
Residual alignment and its effect on weld strength in material-extrusion 3D-printing of polylactic acid
(Elsevier B.V, 2020-06-30)
Gaining a molecular understanding of material extrusion (MatEx) 3D printing is crucial to predicting and
controlling part properties. Here we report the direct observation of distinct birefringence localised to the ...
Poly(ionic liquid)–ionic liquid membranes with fluorosulfonyl derived anions: characterization and biohydrogen separation
(ACS, 2020-04-21)
Clean and sustainable energy production has become a key global issue concerning the world’s energy shortage and environmental problematic. Despite the recognized potential of biohydrogen (bioH2) for sustainable development, ...
Imidazolium-based co-poly(ionic liquid) membranes for CO2/N2 separation
(ACS, 2019-01-04)
The development of efficient carbon dioxide capture and separation technologies is at the fore front of the priorities in the climate change policies. Poly(ionic liquid)s (PILs) have been emerging as extremely promising ...
Synthesis, Structure and Crystallization Behavior of Amphiphilic Hetero-arm Molecular Brushes with Crystallizable Poly(ethylene oxide) and N-Alkyl Side Chains
(ACS, 2020-02-24)
A series of hetero-arm amphiphilic molecular brushes (AMBs) with poly(ethylene glycol) (PEG) and long chain n-alkyl side chains were synthesized via conventional free radical polymerization (FRP) of mainly 4-vinyl benzyl-PEG ...
Crystallization, Orientation and Solid−Solid Crystal Transition of Polybutene‐1 Confined within Nanoporous Alumina
(ACS, 2020-07-31)
The effect of confinement on the crystallization, crystal orientation, and polymorphic crystal transition of bulk and infiltrated polybutene-1 (PB-1) within nanoporous alumina templates (AAO) were studied. After cooling ...
Effect of the crystallization conditions on the exclusion/inclusion balance in biodegradable poly(butylene succinate-ran-butylene adipate) copolymers
(ACS, 2020-07-14)
Biomedical applications of polymers require precise control of the solid-state structure, which is of particular interest for biodegradable copolymers. In this work, we evaluated the influence of crystallization conditions ...
Graphene Oxide–Silver Nanoparticle Nanohybrids: Synthesis, Characterization, and Antimicrobial Properties
(MDPÎ, 2020-02-21)
Drug resistance of pathogenic microorganisms has become a global public health problem, which has prompted the development of new materials with antimicrobial properties. In this context, antimicrobial nanohybrids are an ...
Effect of Organic Modifier and Clay Content on Non-Isothermal Cold Crystallization and Melting Behavior of Polylactide/Organovermiculite Nanocomposites
(MDPI, 2020-02-07)
In clay/polymer nanocomposites, the crystallization behavior and kinetics of the polymer can be affected by the presence of clay, its content and the degree of miscibility between the clay and the polymer matrix. The effect ...
