Thermo-rheological effects on succesful 3D printing of biodegradable polyesters
(Elsevier, 2020-06-23)
Biodegradable polybutylene succinate (PBS) and poly (butylene succinate-ran-adipate) (PBSA) were characterized to find the thermo-rheological bases for 3D printing by Fused Filament Fabrication (FFF). In dynamic viscoelastic ...
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, ...
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 ...
Sequential crystallization and multi-crystalline morphology in PE-b-PEO-b-PCL-b-PLLA tetrablock quarterpolymers
(ACS, 2021-08-10)
We investigate for the first time the morphology and crystallization of two novel tetrablock quarterpolymers of
polyethylene (PE), poly(ethylene oxide) (PEO), poly(ε-caprolactone) (PCL), and poly(L-lactide) (PLLA) with ...
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. ...
Influence of Chemical Structures on Isodimorphic Behavior of Three Different Copolycarbonate Random Copolymer Series
(American Chemical Society, 2020-01-10)
Three series of aliphatic random copolycarbonates, poly(heptane-co-dodecane carbonate) P7C-P12C, poly(butane-co-dodecane carbonate) P4C-P12C and poly(butane-co-heptane carbonate) P4C-P7C, were synthesized by two-step ...
Chemical Structure Drives Memory Effects in the Crystallization of Homopolymers
(ACS, 2020-06-11)
Although the study of melt memory has attracted much interest, the effect of polymer chemical structure on its origin has not been fully elucidated. In this work, we study melt memory effects by Differential Scanning ...
Solid–Solid Crystal Transitions (δ to α) in Poly(hexamethylene carbonate) and Poly(octamethylene carbonate)
(ACS, 2021-07-21)
Poly (hexamethylene carbonate) (PC6) and poly (octamethylene carbonate) (PC8) were studied under different crystallization conditions. Using differential scanning calorimetry (DSC), a new solid-solid transition, denoted α ...
