Influence of the Addition of Polystyrene-blockpoly(methyl methacrylate) Copolymer (PS-b-PMMA) on the Morphologies Generated by Reaction-Induced Phase Separation in PS/PMMA/Epoxy Blends
(Wiley VCH Verlag, 2002-04-11)
Homogeneous solutions of polystyrene (PS) and poly(methyl methacrylate) (PMMA) in diglycidylether of bisphenol A, containing about 8 wt.‐% total thermoplastic, and with or without 0.5 wt.‐% of a PS‐b‐PMMA block copolymer, ...
Double phase separation induced by polymerization in ternary blends of epoxies with polystyrene and poly(methyl methacrylate)
(American Chemical Society, 2001-04)
Ternary blends based on a stoichiometric mixture of diglycidyl ether of bisphenol A (DGEBA) and 4,4'-diaminodiphenyl sulfone (DDS), monodisperse polystyrene (PS, 8.3 × 104 g/mol), and monodisperse poly(methyl methacrylate) ...
Polymer-Dispersed Liquid Crystals with Co-continuous Structures Generated by Polymerization-Induced Phase Separation of EBBA-Epoxy Solutions
(American Chemical Society, 2002-07)
Polymer-dispersed liquid crystals (PDLCs), consisting of a dispersion of LC-rich domains in a polymer matrix, are used in different types of electrooptical devices. Their efficiency can in principle be increased if the LC ...
Self-assembly of gold nanoparticles as colloidal crystals induced by polymerization of amphiphilic monomers
(American Chemical Society, 2008-07)
The self-assembly of inorganic nanoparticles (NPs) into hierarchical structures on different length scales is one of the main aspects of "bottom-up" approaches to create materials with specific electronic, optical, or ...
Evolution of morphologies of a PE-b-PEO block copolymer in an epoxy solvent induced by polymerization followed by crystallization-driven self-assembly of PE blocks during cooling
(Royal Society of Chemistry, 2016-03)
Polymerization-induced nanostructuration combined with crystallization-driven self-assembly was used to generate complex nanostructures in an epoxy network. A PE-b-PEO block copolymer (Mn = 1400; 50 wt% PEO), was dispersed ...
Polymerization-induced phase separation as a one-step strategy to self-assemble alkanethiol-stabilized gold nanoparticles inside polystyrene domains dispersed in an epoxy matrix
(Pergamon-Elsevier Science Ltd, 2012-06)
The rational design of nanoparticle (NP)/polymer composites with advanced functional properties is based on controlling the distribution and self-assembly of NPs in the polymer matrix. In this study we report a new one-step ...
From spherical micelles to hexagonally packed cylinders: the cure cycle determines nanostructures generated in block copolymer/ epoxy blends
(American Chemical Society, 2013-06-04)
Block copolymer (BCP)/epoxy blends have been intensively investigated during the past decade. Macrophase separation of the BCP in the cured thermoset is avoided by selecting one block that is initially immiscible or that ...
Thermodynamic Analysis of the Phase Separation during the Polymerization of a Thermoset System into a Thermoplastic Matrix. I. Effect of the Composition on the Cloud-Point Curves
(John Wiley & Sons Inc, 2004-04)
The cloud‐point curves of polystyrene (PS) mixed with reactive epoxy monomers based on diglycidyl ether of bisphenol A with stoichiometric amounts of 4,4′‐methylenebis(2,6‐diethylaniline) were experimentally studied. A ...
Monofunctional epoxy-POSS dispersed in epoxy - Amine networks: Effect of a prereaction on the morphology and crystallinity of POSS domains
(American Chemical Society, 2007-02)
Several studies have recently reported the use of monofunctional octahedral oligomeric silsesquioxanes (monofunctional POSS) to modify polymer networks. In most of these studies the final material is depicted as a network ...
Thermodynamic analysis of the reaction-induced phase separation in model systems based on blends of a rubber in diepoxide/monoamine precursors
(Wiley, 2003-08)
The reaction-induced phase separation in blends based on a carboxyl-terminated poly(butadiene-co-acrylonitrile) rubber (CTBN), dissolved in diglycidyl ether of bisphenol A (DGEBA) - benzylamine (BA) monomers, was studied. ...
