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 ...
Natural Deep Eutectic Solvents Based on Choline Chloride and Phenolic Compounds as Efficient Bioadhesives and Corrosion Protectors
(American Chemical Society, 2022)
[EN] Natural deep eutectics solvents (NADES), owing to their high solvation capacity and nontoxicity, are actively being sought for many technological applications. Herein, we report a series of novel NADES based on choline ...
(PVDF)2(PEO)2 miktoarm star copolymers: Synthesis and isothermal crystallization leading to exclusive β-phase formation
(Elsevier, 2022-10)
In this work, we study how chain topology can induce different polymorphic behaviors in poly(vinylidene fluoride) (PVDF)-based materials. A linear PVDF precursor with two azido groups at the junction point, (PVDFx-N3)2 and ...
Enhanced and Reusable Poly(hydroxy urethane)-Based Low Temperature Hot-Melt Adhesives
(American Chemical Society, 2022)
[EN] Poly(hydroxy urethane)s (PHUs) based on 5-membered cyclic carbonates have emerged as sustainable alternatives to conventional isocyanate-based polyurethanes. However, while from the point of view of sustainability ...
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 ...
Recent Applications of the Successive Self-nucleation and Annealing (SSA) Thermal Fractionation Technique
(Frontiers Media S.A., 2022-09-28)
Successive Self-nucleation and Annealing (SSA) is a thermal fractionation technique that is performed by Differential Scanning Calorimetry (DSC). The combination of non-isothermal and isothermal steps applied during SSA ...
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 ...
Effect of compatibilizer addition on the surface nucleation of dispersed polyethylene droplets in a self-nucleated polypropylene matrix
(Elsevier, 2022-12)
A significant portion of the global plastics market encompasses the production of polyolefin materials and especially polypropylene (PP) and polyethylene (PE), as commodity polymers with a wide range of applications. ...
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 ...
