Crystallization-Induced Gelling as a Method to 4D Print Low-Water-Content Non-isocyanate Polyurethane Hydrogels
(American Chemical Society, 2021-09-14)
[EN]The use of three-dimensional (3D) printable hydrogels for biomedical applications has attracted considerable attention as a consequence of the ability to precisely define the morphology of the printed object, allowing ...
Even-odd Effect in Aliphatic Polycarbonates with Different Chain Lengths: from Poly (hexamethylene carbonate) to Poly (dodecamethylene carbonate)
(ACS, 2020-12-17)
We have characterized a series of aliphatic polycarbonates synthesized by organocatalysis containing a variable number of methylene groups (nCH2) in their repeat units ranging from nCH2 = 6 to 12. The melting and crystallization ...
Ionic Polyureas—A Novel Subclass of Poly(Ionic Liquid)s for CO2 Capture
(MDPI, 2020-09-18)
The growing concern for climate change and global warming has given rise to investigations in various research fields, including one particular area dedicated to the creation of solid sorbents for efficient CO2 capture. ...
Organocatalyzed Polymerization of PET-mb-poly(oxyhexane) Copolymers and Their Self-Assembly into Double Crystalline Superstructures
(ACS Publications, 2019-08-30)
Double crystalline multi-block copolymers exhibit two well-defined melting temperatures associated with the two phases formed by their constituent blocks. The crystalline superstructure formed in these copolymers is complex ...
Synthesis, Structure, Crystallization and Mechanical Properties of Isodimorphic PBS-ran-PCL Copolyesters
(MDPI, 2021-07-09)
Isodimorphic behavior is determined by partial inclusion of comonomer segments within the crystalline structure and arises from the comparatively similar repeating chain units of the parental homopolymers. Isodimorphic ...
Effect of Chain Stereoconfiguration on Poly(3-hydroxybutyrate) Crystallization Kinetics
(American Chemical Society, 2022-08)
Poly(3-hydroxybutyrate) (PHB) is naturally accumulated by bacteria but can also be synthesized chemically. Its processability is limited, as it tends to degrade at temperatures above its melting temperature; hence, ...
Using Successive Self-nucleation and Annealing (SSA) to detect the solid-solid transitions in poly (hexamethylene carbonate) and poly (octamethylene carbonate)
(ACS, 2021-10-26)
Solid-solid transitions in poly (hexamethylene carbonate) (PC6) and poly (octamethylene carbonate) (PC8), denoted δ to α transition, have been investigated, using self-nucleation and Successive Self-nucleation and Annealing ...
Self-healable dynamic poly(urea-urethane) gel electrolyte for lithium batteries
(Royal Society of Chemistry, 2022)
[EN] Self-healing materials are actively studied in order to extend the lifetime and performance of batteries. Dynamic covalent networks have recently emerged as one of the best self-healable materials which allow thermosets ...
Enhanced and Reusable Poly(hydroxy urethane)-Based Low Temperature Hot-Melt Adhesives
(American Chemical Society, 2022)
[EN] Poly(hydroxy urethane)s (PHUs) based on 5-membered cyclic carbonates have emerged as sustainable alternatives to conventional isocyanate-based polyurethanes. However, while from the point of view of sustainability ...
3D Printed Bioplastics with Shape-Memory Behavior Based on Native Bovine Serum Albumin
(ACS, 2022-04-19)
Bio-based plastics that can supplant petroleum-derived materials are necessary to meet the future demands of sustainability in the life cycle of plastic materials. While there are significant efforts to develop protein-based ...
