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 self-nucleation of PLA, PBS and PCL in their immiscible binary and ternary blends
(Elservier, 2019-06-13)
Three semicrystalline polyesters, poly(lactic acid), poly(caprolactone) and poly(butylene succinate) (PLA, PCL and PBS) were melt blended to prepare binary and ternary systems of selected compositions. In binary blends ...
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 ...
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 ...
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 ...
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 ...
