Biobased thermosetting epoxy foams: Mechanical and thermal characterization
(American Chemical Society, 2015-05-22)
Thermosetting epoxy foams were synthesizedby replacing the commercial synthetic epoxy resin by abiogenic epoxidized vegetable oil. Foam formulations weredeveloped avoiding the use of amine hardeners, organicvolatile compounds ...
Bio-based thermosetting epoxy foams: mechanical and thermal characterization
(American Chemical Society, 2015-07-06)
Thermosetting epoxy foams were synthesized by replacing the commercial synthetic epoxy resin by a biogenic epoxidized vegetable oil. Foam formulations were developed avoiding the use of amine hardeners, organic volatile ...
Epoxy networks based on solutions of silsesquioxanes functionalized with 3-glycidoxypropyl groups in diglycidylether of bisphenol A (DGEBA)
(Springer, 2001-10-20)
In previous publications we reported the synthesis and characterization of silsesquioxanes derived from the hydrolytic condensation of (3-glycidoxypropyl) trimethoxysilane (GPMS) using diglycidylether of bisphenol A (DGEBA) ...
Zirconium-methacrylate oxoclusters as new hybrid materials for the modification of epoxy systems
(Springer, 2015-04-01)
Oxozirconium clusters bearing methacrylate moiety (ZrMe) were synthesized by sol-gel process and used in epoxy networks to develop epoxy-based nanocomposites with potential application as encapsulant for light-emitting ...
Linear viscoelasticity, extensional viscosity, and oxygen permeability of nanocomposites based on propylene copolymer and organoclay
(John Wiley & Sons Inc, 2018-02-13)
Random propylene-terpolymer (PEBC)/organophilic montmorillonite nanocomposites were prepared by melt mixing, using PEBC modified with maleic anhydride (PEBCg) as compatibilizer. Clay concentrations up to 8 wt %, ...
Study of the addition of poly(ethylene-co-methyl acrylate-co-glycidyl methacrylate) thermoplastic to epoxy resin for use in self-healing composites
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIA E ENGENHARIA DE MATERIAIS, 2017-04-28)
Repair of damaged composite structural elements to restore pristine conditions and
meet regulatory requirements can be a great challenge. Thus, materials capable of
self-healing when damaged are of great interest. In one ...
Energías de dispersión y surfactantes en una solución de nanotubos de carbono en agua: aplicaciones en pastas de cemento portland
(Manizales - Ciencias Exactas y Naturales - Maestría en Ciencias - FísicaDepartamento de Física y QuímicaUniversidad Nacional de Colombia - Sede Manizales, 2020)
El presente trabajo se centra en estudiar la optimización de las variables: energía y molaridad del dispersante, en el proceso de dispersión impulsado por sonicación de nanotubos de carbono de pared múltiple en una solución ...
Development of an epoxy-bio-epoxy system and its use in the construction of encapsulated elements for decorative use
(Universidad Católica de ColombiaFacultad de IngenieríasBogotáMaestría en Ingeniería y Gestión de la Innovación, 2022)
This project studies the formulation of an epoxy system for use in artistic encapsulation applications, with eye-catching and customized finishes. The motivation stems from the need to solve some of the problems of epoxy ...
