Nanocomposites with superparamagnetic behavior based on a vegetable oil and magnetite nanoparticles
(Pergamon-Elsevier Science Ltd, 2014-01)
The direct reaction of unmodified tung oil and styrene initiated by boron trifluoride diethyl etherate allowed obtaining thermoset polymers with valuable properties like shape memory behavior. On the other hand, the addition ...
Core-crystalline nanoribbons of controlled length via diffusion-limited colloid aggregation
(Royal Society of Chemistry, 2019-05-21)
It has been previously reported that poly(ethylene) (PE)-based block copolymers self-assemble in certain thermosetting matrices to form a dispersion of one-dimensional (1D) nanoribbons. Such materials exhibit exceptional ...
Tetramethyl guanidine-assisted synthesis and thermal crosslinking of multifunctional benzoxazine monomers based on natural phloretic acid
(John Wiley & Sons Inc, 2021-09)
An efficient strategy to synthesize novel biobased multifunctional benzoxazine compounds was developed using the 1,1,3,3-tetramethyl guanidine (TMG)-triggered esterification of natural phloretic acid with organic halides ...
Comparison of morphologies and mechanical properties of crosslinked epoxies modified by polystyrene and poly(methyl methacrylate)) or by the corresponding block copolymer polystyrene-b-poly(methyl methacrylate)
(Elsevier, 2005-03)
Polystyrene (PS, Mn=28,400, PI=1.07), poly(methyl methacrylate) (PMMA, Mn=88,600, PI=1.03), and PS (50,000)-b-PMMA (54,000) (PI=1.04), were used as modifiers of an epoxy formulation based on diglycidyl ether of bisphenol ...
Epoxy vitrimers: The effect of transesterification reactions on the network structure
(MDPI AG, 2018-01-03)
Vitrimers are covalently crosslinked polymers that behave as conventional thermosets below the glass transition temperature (Tg) but can flow above a particular temperature, Tv > Tg, by bond exchange reactions. In epoxy ...
Controlling the generation of bilayer and multilayer vesicles in block copolymer/epoxy blends by a slow photopolymerization process
(Royal Society of Chemistry, 2017-09)
Vesicles are a highly attractive morphology to achieve in micellar dispersions of block copolymers (BCP) in epoxy thermosets due to the fact that small amounts can affect a large volume fraction of the matrix, a fact that ...
Making Benzoxazines Greener: Design, Synthesis, and Polymerization of a Biobased Benzoxazine Fulfilling Two Principles of Green Chemistry
(American Chemical Society, 2018-10)
Sesamol and furfurylamine are used to synthesize a novel benzoxazine monomer as part of the quest to develop greener benzoxazine monomers simultaneously fulfilling two Principles of Green Chemistry, the use of renewable ...
A Model System for the Thermodynamic Analysis of Reaction‐Induced Phase Separation: Solutions of Polystyrene in Bifunctional Epoxy/Amine Monomers
(Wiley VCH Verlag, 2004-03)
A model system, consisting of a linear polymer dissolved in a bifunctional monomer/co‐monomer solvent, was selected to test the applicability of the Flory‐Huggins (FH) theory in the absence of the usual assumptions present ...
High-Energy Dissipation Performance in Epoxy Coatings by the Synergistic Effec of Carbon Nanotube/Block Copolymer Conjugate
(American Chemical Society, 2017-01)
Hierarchical assembly of hard/soft nanoparticles holds great potential as reinforcements for polymer nanocomposites with tailored properties. Here, we present a facile strategy to integrate polystyrene-grafted carbon ...
