Self-nucleation Effects on Polymer Crystallization
(ACS, 2020-05-28)
The existence of a “memory” of the previous crystalline state, which survives melting and enhances re-crystallization kinetics by a self-nucleation process, is well-known in polymer crystallization studies. Despite being ...
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 ...
Competition between Chain Extension and Crosslinking in Polyamide 1012 during High Temperature Thermal Treatments as Revealed by SSA Fractionation
(ACS, 2021-08-03)
Self-nucleation and annealing (SSA) is an efficient way to thermally fractionate semi-crystalline polymers. The thermal fractions produced by SSA have distinct melting points that correspond to different average lamellar ...
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 ...
Melt Memory Effects in Poly(butylene succinate) Studied by Differential Fast Scanning Calorimetry
(MDPI, 2020-11-26)
It is widely accepted that melt memory effect on polymer crystallization depends on thermal history of the material, however a systematic study of the different parameters involved in the process has been neglected, so ...
Phase Transitions in Poly(vinylidene fluoride)/Polymethylene-Based Diblock Copolymers and Blends
(MDPI, 2021-07-24)
The crystallization and morphology of two linear diblock copolymers based on polymethylene (PM) and poly(vinylidene fluoride) (PVDF) with compositions PM23-b-PVDF77 and PM38-b-PVDF62 (where the subscripts indicate the ...
Flame Retardant Polyphosphoester Copolymers as Solid Polymer Electrolyte for Lithium Batteries
(RSC, 2021-05-19)
Solid-state lithium batteries are considered one of the most promising battery systems due to their high volumetric energy density and safety. Poly(ethylene oxide) (PEO) is the most commonly used solid polymer electrolyte ...
Fast successive self-nucleation and annealing (SSA) thermal fractionation protocol for the characterization of polyolefin blends from mechanical recycling
(Wiley, 2022-04-29)
The sorting stage of mechanical recycling of post-consumer polyolefins has severe challenges. Polypropylene (PP) is often contaminated with polyethylene (PE) and vice versa. To meet quality requirements, characterization ...
Self-assembly and crystallization of double crystalline aliphatic thermoplastic biopolyurethane and its nucleation with cellulose nanocrystals
(Elsevier, 2022-01-13)
[EN] An aliphatic segmented thermoplastic biopolyurethane (STPU), based on aliphatic hexamethylene diisocyanate (HDI) and 1,3 propanediol (1,3PD) as urethane rich phase and a poly(sebacate) as a macrodiol phase, with ~50 ...
