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 ...
Tunable enzymatic biodegradation of poly(butylene succinate): biobased coatings and self-degradable films
(Elsevier, 2023-05)
Biodegradation of polyesters driven by enzymes is considered as one of the most effective way of degradation of these materials, as a way to control plastics accumulation in the environment. In this study, we present two ...
Crystallization, morphology and self-assembly of double, triple and tetra crystalline block polymers
(Elsevier, 2023-04)
This review compiles a comprehensive analysis of the crystallization behaviour and self-assembly of block copolymers with up to four potentially crystallizable phases. It covers the recent advances in block copolymer ...
The effect of initial molecular weight on the structural evolution of Polyamide 1012 during high-temperature thermal treatments as revealed by Successive Self-Nucleation and Annealing
(ACS, 2022-08-24)
Successive self-nucleation and annealing (SSA) can thermally fractionate semi-crystalline polymers, thus detecting the characteristic structural features that lead to specific melting point distributions (corresponding to ...
Supramolecular Networks Obtained by Block Copolymer Self-Assembly in a Polymer Matrix: Crystallization Behavior and Its Effect on the Mechanical Response
(American Chemical Society, 2023-02)
In recent years, there has been growing interest in the study of supramolecular networks obtained by self-assembly of amphiphilic molecules due to their responsive behavior to different external stimuli. The possibility ...
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 ...
