Reduced Graphene Oxide/Polymer Monolithic Materials for Selective CO2 Capture
(MDPI, 2020-04-17)
Polymer composite materials with hierarchical porous structure have been advancing in many different application fields due to excellent physico-chemical properties. However, their synthesis continues to be a highly ...
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 ...
Reprogrammable Permanent Shape Memory Materials Based on Reversibly Crosslinked Epoxy/PCL Blends
(MDPI, 2020-03-29)
Epoxy/Polycaprolactone (PCL) blends cured with a conventional diamine (4,4′-diaminodiphenylmethane, DDM) and with different amounts of a disulfide containing diamine (4, 4´-dithioaniline, DSS) were prepared through melting. ...
Analysis of the Process Parameters for Obtaining a Stable Electrospun Process in Different Composition Epoxy/Poly ε-Caprolactone Blends with Shape Memory Properties
(MDPI, 2019-03-12)
In this work Poly epsilon-caprolactone (PCL)/ Diglycidyl ether of bisphenol A (DGEBA) blends were electrospun and the obtained mats were UV cured to achieve shape memory properties. In the majority of studies, when blends ...
Isomorphic polyoxyalkylenes copolyethers obtained by copolymerization of aliphatic diols
(American Chemical Society, 2019-05-01)
Isomorphism in random copolymers occurs when comonomer units can crystallize within a single crystalline lattice in the entire composition range. This ideal behavior is rare in random copolymers and only a few examples of ...
Improving the barrier character of poly(caprolactone): transport properties and free volume of immiscible blends
(Elsevier, 2019-03-11)
Miscible and thermally stable blends of biodegradable poly(butylene adipate-co-terephthalate) (PBAT) with poly(hydroxy ether of bisphenol A) (PH) are investigated to obtain membranes for packaging applications. Previously ...
Recyclable, remendable and healing polyurethane/acrylic coatings from UV curable waterborne dispersions containing Diels-‐Alder moieties
(Elsevier, 2020-02-01)
The aim of the present work is to increase the sustainability of UV curable waterborne polyurethane dispersions using the Diels-Alder chemistry. In this way, the obtaining of crosslinked polyurethane coatings presenting ...
Miscibility and degradation of polymer blends based on biodegradable poly(butylene adipate-co-terephthalate)
(Elsevier, 2018-02-21)
The aim of this work is to analyse the effect of the preparation method on the miscibility of poly(butylene adipate-co-terephthalate) (PBAT) and poly(hydroxy ether of bisphenol A) (PH) blends and to provide a better ...
Tributyl citrate as an effective plasticizer for biodegradable polymers: effect of the plasticizer on the free volume, transport and mechanical properties
(Society of Chemical Industry. Wiley, 2018-06-16)
The effectiveness of tributyl citrate (TbC) as plasticizer for polylactide (PLLA) and poly(hydroxybutyrate) (PHB) was analyzed in order to improve the ductility of these polymers and make them good candidates for food ...
One pot stimuli-responsive linear waterborne polyurethanes via Diels-Alder reaction
(Elsevier, 2019-01-25)
Different strategies were used to obtain waterborne polyurethanes containing Diels-Alder moieties. In the first one (two pot), furan and maleimide end capped waterborne polyurethane dispersions were synthesized with the ...
