Fractionated crystallization in semicrystalline polymers
(Elsevier, 2021-02-16)
The crystallization of heterogeneously nucleated bulk polymers typically occurs in a single exothermic process, within a narrow temperature range, i.e., a single exothermic peak is detected by Differential Scanning Calorimetry ...
Direct Identification of Three Crystalline Phases in PEO-b-PCL-b-PLLA Triblock Terpolymer by In Situ Hot-Stage Atomic Force Microscopy
(Elsevier, 2020-08-04)
In this work, we provide a detailed description of the tri-lamellar nanoscale morphology of a triple crystalline PEO-b-PCL-b-PLLA triblock terpolymer obtained by Hot-Stage Atomic Force microscopy (AFM) imaging and Wide ...
Nucleation of poly(lactide) partially wet droplets in ternary blends with poly(butylene succinate) and poly(ε-caprolactone)
(ACS, 2020-02-25)
This work presents the first investigation on the crystallization behavior of partially wet droplets in immiscible ternary blends. Poly(lactide), poly(ε-caprolactone), and poly(butylene succinate) (PLA, PCL, and PBS, ...
Controlling the Isothermal Crystallization of Isodimorphic PBS-ran-PCL Random Copolymers by Varying Composition and Supercooling
(MDPI, 2019-12-20)
In this work, we study for the first time, the isothermal crystallization behavior of isodimorphic random poly(butylene succinate)-ran-poly(ε-caprolactone) copolyesters, PBS-ran-PCL, previously synthesized by us. We perform ...
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 ...
Polyethylene Oxide/Sodium Sulfonamide Polymethacrylate Blends as Highly Conducting Single-Ion Solid Polymer Electrolytes
(American Chemical Society, 2023-04)
In this work, blends of polyethylene oxide (PEO) and poly(sodium 1-[3-(methacryloyloxy)propylsulfonyl]-1-(trifluoromethanesulfonyl) imide) (PNaMTFSI) in different compositions were investigated for their application as ...
Influence of FFF Process Conditions on the Thermal, Mechanical, and Rheological Properties of Poly(hydroxybutyrate-co-hydroxy Hexanoate)
(MDPI, 2023-04-07)
Polyhydroxyalkanoates are natural polyesters synthesized by microorganisms and bacteria. Due to their properties, they have been proposed as substitutes for petroleum derivatives. This work studies how the printing conditions ...
Morphology, Nucleation, and Isothermal Crystallization Kinetics of Poly(Butylene Succinate) Mixed with a Polycarbonate/MWCNT Masterbatch
(MDPI, 2018-04-10)
In this study, nanocomposites were prepared by melt blending poly(butylene succinate) (PBS) with a polycarbonate (PC)/multi-wall carbon nanotubes (MWCNTs) masterbatch, in a twin-screw extruder. The nanocomposites contained ...
Isothermal Crystallization Kinetics and Morphology of Double Crystalline PCL/PBS Blends Mixed with a Polycarbonate/MWCNTs Masterbatch
(MDPI, 2019-04-15)
In this work, the 70/30 and 30/70 w/w polycaprolactone (PCL)/polybutylene succinate (PBS) blends and their corresponding PCL/PBS/(polycarbonate (PC)/multiwalled carbon nanotubes (MWCNTs) masterbatch) nanocomposites were ...
Nucleation of Poly(lactide) on the Surface of Different Fibers
(ACS Publications, 2019-08-14)
The nucleation process of poly(lactide) (PLA) on a series of fibers was studied by means of in-situ Polarized Optical Microscope (POM) during crystallization. Several synthetic and natural fibers (PLLA stereocomplex fibers ...
