Confined Crystallization of Polymers within Nanopores
(ACS, 2021-08-03)
Crystallization of polymeric materials under nanoscopic confinement is highly relevant for nanotechnology applications. When a polymer is confined within rigid nanoporous anodic aluminum oxide (AAO) templates, the ...
Direct Relationship between Dispersion and Crystallization Behavior in Poly(ethylene oxide)/Poly(ethylene glycol)-g-Silica Nanocomposites
(American Chemical Society, 2021-02-08)
The inclusion of polymer-grafted nanoparticles (PGNPs) can impart various
functional properties to polymer nanocomposites (PNCs). For semicrystalline
polymers, we can control the spatial dispersion of PGNPs and presumably ...
Polycaprolactone Adsorption and Nucleation onto Graphite Nanoplates for Highly Flexible, Thermally Conductive, and Thermomechanically Stiff Nanopapers
(American Chemical Society, 2021-12-15)
[EN] Free-standing nanopapers based on graphene and its related materials have been widely studied and proposed for flexible heat spreader applications. Given that these materials are typically brittle, this work reports ...
Suppression of the Self-Nucleation Effect of Semicrystalline Polymers by Confinement
(ACS, 2021-04-15)
The melt memory effect is well-known in polymer crystallization. It is caused by self-nuclei that
persist above the melting temperature. The origin and physical nature of self-nuclei are still under
debate. In this work, ...
Using Successive Self-nucleation and Annealing (SSA) to detect the solid-solid transitions in poly (hexamethylene carbonate) and poly (octamethylene carbonate)
(ACS, 2021-10-26)
Solid-solid transitions in poly (hexamethylene carbonate) (PC6) and poly (octamethylene carbonate) (PC8), denoted δ to α transition, have been investigated, using self-nucleation and Successive Self-nucleation and Annealing ...
Composition Dependent Miscibility in the Crystalline State of Polyamide 6 /Polyamide 4,10 Blends: from Single to Double Crystalline Blends
(Elsevier, 2021-02-22)
In this work, we studied the composition-dependent miscibility of polyamide 6 and biobased polyamide 4,10 (PA6/PA410) blends, as triggered by crystallization driven phase segregation. The blends were prepared by extrusion ...
Fractionated crystallization in semicrystalline polymers
(Elsevier, 2021-02-16)
The crystallization of heterogeneously nucleated bulk polymers typically occurs in a single exothermic process, within a narrow temperature range, i.e., a single exothermic peak is detected by Differential Scanning Calorimetry ...
Solid–Solid Crystal Transitions (δ to α) in Poly(hexamethylene carbonate) and Poly(octamethylene carbonate)
(ACS, 2021-07-21)
Poly (hexamethylene carbonate) (PC6) and poly (octamethylene carbonate) (PC8) were studied under different crystallization conditions. Using differential scanning calorimetry (DSC), a new solid-solid transition, denoted α ...
