Epoxy-Layered Silicate and Epoxy MWCNTs Nanocomposites

Applied Mechanics and Materials, 2011
The paper deals with the rheological properties of epoxy resin additivated with organically modified montmorillonites, carbon nanotubes and nanocarbon. The paper also presents the influence of nanoadditives over composites mechanical properties. The epoxy polymer is diglycidyl ether of bisphenol A (DGEBA) and the curing agent is an aliphatic tetraamine.

Epoxy‐amine networks with varying epoxy polydispersity

Journal of Applied Polymer Science, 2014
ABSTRACTSolid, high molecular weight DGEBA‐based epoxies were blended with high purity liquid DGEBA to create several resins with equivalent epoxy equivalent weights, but with polydispersity indices (PDIs) ranging from 3 to over 10. The resins were cured with a stoichiometric amount of polyetheramine and compared to a nonblended epoxy with PDI of 1.8 ...

Toughening of epoxy systems by brominated epoxy

Polymer Engineering & Science, 2018
Blends of brominated epoxy (BE) and conventional epoxy resins were studied following curing with aliphatic triethylenetetramine (TETA), etheric (polyether diamine‐ PEA4), and aromatic (3,3′‐diamino diphenyl sulfone [DDS]) hardeners. The addition of BE resulted in an increase in Tg in all tested blends. Blends with 50 wt% BE cured with TETA demonstrated

Epoxy Functionalized Hyberbranched Polymer/Epoxy Blends

1999
Abstract : In this preliminary study, two novel hyperbranched polymer (HBP)/epoxy blends were evaluated to determine their efficiency as blend modifiers and tougheners in a brittle epoxy resin. The HBP is miscible in the epoxy and phase separates as cure progresses to form a two-phase system with a dispersed secondary phase of HBP/epoxy compatibilizers

Epoxy+liquid crystalline epoxy coreacted networks: II. Mechanical properties

Polymer, 2002
Abstract The effect of coreacting diglycidyl ether of bisphenol F (DGEBP-F) with diglycidyl ether of 4,4′-dihydroxybiphenol (DGE-DHBP) on mechanical properties is investigated. DGE-DHBP shows a liquid crystal (LC) transition upon curing. Tensile, impact and fracture toughness test results are evaluated.

Thiol-epoxy and Amine-epoxy ‘Click’ Polymerizations

2018
Although an old reaction, the interest in the thiol-epoxy reaction, especially as a polymerization process, is only recent. The power of this chemistry lies in its efficiency and operation under ambient conditions, the commercial availability of a vast variety of thiol- and epoxide-carrying molecules that can be utilized as monomers, the long list of ...

Epoxy + Liquid Crystalline Epoxy Coreacted Networks

Molecular reinforcement through in-situ polymerization of liquid crystalline epoxies (LCEs) and a non-liquid crystalline epoxy has been investigated. Three LCEs: diglycidyl ether of 4,4'-dihydroxybiphenol (DGE-DHBP) and digylcidyl ether of 4-hydroxyphenyl-4"-hydroxybiphenyl-4'-carboxylate (DGE-HHC), were synthesized and blended with diglycidyl ether of
