Physicochemical Properties and Proposed Mechanism in the Obtainment of 4-Hidroxycoumarin Conjugated Polymers Using MALDI-Tof Analysis
(International Organization of Scientific Research, 2016-02)
The mechanism for the poly-condensation event of conjugated polymers with ending 4-hydroxycoumarin has been proposed. It happened under H2SO4 acidic conditions only using enolic-coumarins without any substituent at third ...
Polymer informatics for QSPR prediction of tensile mechanical properties. Case study: Strength at break
(American Institute of Physics, 2022-05)
The artificial intelligence-based prediction of the mechanical properties derived from the tensile test, plays a key role in assessing the application profile of new polymeric materials, specifically in the design stage, ...
Determination of Nanoscale Mechanical Properties of Polymers via Plasmonic Nanoantennas
(American Chemical Society, 2020-06)
Nanotechnology and the consequent emergence of miniaturized devices are driving the need to improve our understanding of the mechanical properties of a myriad of materials. Here we focus on amorphous polymeric materials ...
Efficient modeling of distributions of polymer properties using probability generating functions and parallel computing
(Pergamon-Elsevier Science Ltd, 2019-09-02)
High-fidelity models of polymer processes should include the prediction of distributions of polymer properties, including multivariate distributions. Deterministic models with this capability usually involve a large system ...
Effect of the Processing-Induced Morphology on the Mechanical Properties of Biodegradable Extruded Films Based on Poly(lactic acid) (PLA) Blends
(Springer/Plenum Publishers, 2019-09)
Biodegradable films based on poly(lactic acid) blends were obtained by cast extrusion. Their tensile and fracture behaviorwas investigated and the effect of the processing conditions through the extrusion rolling speed on ...
Nanoindentation: An emerging technique for polymer surface mechanical characterization
(Budapest University of Technology and Economics, 2007-10)
Polymer surfaces are the phase boundaries that reside between the bulk polymer and the outer environments. For many applications they have to be modified using physical or chemical processes to achieve the desired functional ...
Mechanical properties of linseed oil monoglyceride maleate/styrene copolymers
(John Wiley & Sons Inc, 2005-08)
In this study, rigid thermoset polymers were prepared from radical copolymerization of linseed oil monoglyceride maleates with styrene (St). First, linseed oil monoglycerides (LOMGs) were obtained from the reaction of ...
Influence of the addition of montmorillonite to the matrix of unidirectional glass fibre/epoxy composites on their mechanical and water absorption properties
(Elsevier, 2008-11)
Epoxy nanocomposites were used as matrix of glass fibre-reinforced composites. The dispersion of the clay in the epoxy was studied by X-ray diffraction analyses given strong evidence that the clay formed an intercalated ...
Polyethylene/(organo-montmorillonite) composites modified with ethylene/methacrylic acid copolymer: Morphology and mechanical properties
(Elsevier, 2008-12-12)
Several composites based on high-density polyethylene (PE), organically modified montmorillonite (OMMT) and ethylene/methacrylic acid copolymer (EMAA) were prepared by melt compounding. Three Na+-montmorillonites (MMT) of ...
How can polydispersity information be integrated in the QSPR modeling of mechanical properties?
(Taylor & Francis, 2022-01)
Polymer informatics is an emerging discipline that has benefited from the strong development that data science has experienced over the last decade. In particular, machine learning methods are useful to infer QSPR (Quantitative ...
