Nucleation modalities in poly(lactide), poly(butylene succinate) and poly(ε-caprolactone) ternary blends with partial wetting morphology
(John Wiley & Sons, Inc., 2020-08-17)
Ternary biodegradable polymer blends of poly(lactic acid) (PLA), poly(butylene succinate) (PBS), and poly(ε‐caprolactone) (PCL) with the composition 45/10/45 wt% and exhibiting partial‐wetting morphology were prepared. In ...
Electroactive 3D printable poly (3,4-ethylenedioxythiophene)-graft-poly(ε-caprolactone) copolymers as scaffolds for muscle cell alignment
(Royal Society of Chemistry, 2021-12-02)
The development of tailor-made polymers to build artificial three-dimensional scaffolds to repair damaged skin tissues is gaining increasing attention in the bioelectronics field. Poly (3,4-ethylene dioxythiophene) (PEDOT) ...
Polyether Single and Double Crystalline Blends and the Effect of Lithium Salt on Their Crystallinity and Ionic Conductivity
(MDPI, 2021-06-25)
In this work, blends of Poly(ethylene oxide), PEO, and poly(1,6-hexanediol), PHD, were prepared in a wide composition range. They were examined by Differential Scanning Calorimetry (DSC), Polarized Light Optical Microscopy ...
Composition Dependent Miscibility in the Crystalline State of Polyamide 6 /Polyamide 4,10 Blends: from Single to Double Crystalline Blends
(Elsevier, 2021-02-22)
In this work, we studied the composition-dependent miscibility of polyamide 6 and biobased polyamide 4,10 (PA6/PA410) blends, as triggered by crystallization driven phase segregation. The blends were prepared by extrusion ...
Study of the interlayer adhesion and warping during material extrusion-based additive manufacturing of a carbon nanotube/biobased thermoplastic polyurethane nanocomposite
(Elsevier, 2021-04-07)
A thermoplastic bio-polyurethane from renewable sources (TPU) and the nanocomposite developed by mixing it
with carbon nanotubes (CNT) are investigated as potentially adequate for Material Extrusion-based Additive
Manufacturing ...
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, ...
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 ...
