Continuous Cooling Curve Diagrams of Isotactic-Polypropylene/Polyethylene Blends: Mutual Nucleating Effects under Fast Cooling Conditions
(American Chemical Society, 2021-05-25)
Crystallization kinetics under processing-relevant cooling conditions of polyethylene/isotactic-polypropylene (PE/PP) blends, with compositions similar to real recycled blends, was investigated through an in situ temperature ...
Crystallization of a Self-Assembling Nucleator in Poly(L-lactide) Melt
(American Chemical Society, 2021-09-01)
[EN]In the present work, crystallization of a soluble nucleator N, N′, N″-tricyclohexyl-1,3,5-benzenetricarboxylamide (TMC-328) in a poly(l-lactic acid) (PLLA) matrix has been studied at different temperatures. Based on ...
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 ...
Crystallization and Morphology of Triple Crystalline Polyethylene-b-poly(ethylene oxide)-b-poly(ε-caprolactone) PE-b-PEO-b-PCL Triblock Terpolymers
(MDPI, 2021-09-16)
The morphology and crystallization behavior of two triblock terpolymers of polymethylene, equivalent to polyethylene (PE), poly (ethylene oxide) (PEO), and poly (ε-caprolactone) (PCL) are studied: PE227.1-b-PEO4615.1-b-PCL3210.4 ...
Surface Roughness Enhances Self-Nucleation of High-Density Polyethylene Droplets Dispersed within Immiscible Blends
(American Chemical Society, 2022)
[EN] Highly linear or high-density polyethylenes (HDPEs) have an intrinsically high nucleation density compared to other polyolefins. Enhancing their nucleation density by self-nucleation is therefore difficult, leading ...
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 ...
Effect of the TrFE Content on the Crystallization and SSA Thermal Fractionation of P(VDF-co-TrFE) Copolymers
(MDPI, 2022-09-08)
In this contribution, we study the effect of trifluoro ethylene (TrFE) comonomer content (samples with 80/20, 75/25, and 70/30 VDF/TrFE molar ratios were used) on the crystallization in P(VDF-co-TrFE) in comparison with a ...
Temperature modulated DSC for composition analysis of recycled polyolefin blends
(Elsevier, 2022-09)
Post-consumer plastic waste contains blends of numerous types of polyethylene (PE) and isotactic polypropylene (i-PP), whose recycling is challenging due to the complexity of this waste stream. A comprehensive knowledge ...
Surface Nucleation of Dispersed Droplets in Double Semicrystalline Immiscible Blends with Different Matrices
(Wiley, 2022-11)
When a minor semicrystalline phase is dispersed in an immiscible blend with another polymer in the form of isolated droplets, its crystallization behavior is dominated by nucleation. In particular, nucleation can occur in ...
