Promotion of self-nucleation with latent Form I nuclei in polybutene-1 and its copolymer
(American Chemical Society, 2018-08-02)
The formation of Form I nuclei of polybutene-1 (PB-1) and its copolymer with polyethylene (PB1-ran-PE) has been studied by means of modified self-nucleation protocols. Even when the self-nucleation temperature was high ...
Crystallization of isodimorphic aliphatic random copolyesters: pseudo-eutectic behavior and double-crystalline materials
(Elservier, 2018-02-28)
Isodimorphic random copolyesters are intriguing polymeric materials that can crystallize in their entire composition range, despite the random distribution of comonomer units along their chains. This behavior stems from ...
Nucleation and crystallization in bio-based immiscible polyester blends
(Springer, 2019-08-21)
Bio-based thermoplastic polyesters are highly promising materials as they combine interesting thermal and physical properties and in many cases biodegradability. However, sometimes the best property balance can only be ...
The origin of memory effects in the crystallization of polyamides: Role of hydrogen bonding
(Elsevier, 2019-12-23)
The effect of hydrogen bonding stability on the memory effects in the crystallization of long chain polyamides have been investigated by the self-nucleation calorimetric technique. Self-nucleation is characterized by three ...
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 ...
