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 ...
Crystallization Kinetics and Nanoparticle Ordering in Semicrystalline Polymer Nanocomposites
(Elsevier, 2022-03-13)
There has been considerable interest in the nucleation and crystallization of polymers in the presence of nanoparticles (NPs, or nanofillers in general, NFs). Most of the extensive work in this area has focused on anisotropic, ...
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 ...
The effect of initial molecular weight on the structural evolution of Polyamide 1012 during high-temperature thermal treatments as revealed by Successive Self-Nucleation and Annealing
(ACS, 2022-08-24)
Successive self-nucleation and annealing (SSA) can thermally fractionate semi-crystalline polymers, thus detecting the characteristic structural features that lead to specific melting point distributions (corresponding to ...
Biodegradable binary blends of poly (butylene succinate) or poly (ε-caprolactone) with poly (butylene succinate-ran-ε-caprolactone) copolymers: Crystallization behavior
(Elsevier, 2022-08-12)
Poly (butylene succinate) (PBS) and polycaprolactone (PCL) are two immiscible biocompatible and biodegradable polymers. Aiming to combine the properties of these biodegradable polymers, this work explores for the first ...
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 ...
Unexpected structural properties in the saturation region of the odd-even effects in aliphatic polyethers: Influence of crystallization conditions
(ACS, 2022-01-04)
A series of aliphatic polyethers with different chain lengths (nCH2= 6 to 12, and 16) is
studied employing differential scanning calorimetry and X-rays scattering. The
calorimetric and structural behavior of samples ...
Experimental and Data Fitting Guidelines for the Determination of Polymer Crystallization Kinetics
(Springer Nature, 2022-05-05)
The crystallization kinetics of semicrystalline polymers is often studied with isothermal experiments and analyzed by fitting the data with analytical expressions of the Avrami and Lauritzen and Hoffman (LH) theories. To ...
Peculiar self-nucleation behavior of a polybutene-1/ethylene random copolymer
(Wiley, 2021-07-31)
The self-nucleation behavior of a polybutene-1/ethylene random copolymer, P(B1-ran-E), which undergoes a complex crystal-crystal transition behavior, has been studied in detail. Similar to PE random copolymers, this material ...
Generating Triple Crystalline Superstructures in Melt Miscible PEO-b-PCL-b-PLLA Triblock Terpolymers by Controlling Thermal History and Sequential Crystallization
(WILEY-VCH, 2019-09-10)
The morphology, crystallization behavior and properties of multi-crystalline polymer systems based on triple crystalline biodegradable PEO-b-PCL-b-PLLA triblock terpolymers are reviewed. The triblock terpolymers, with ...
