Salt Template Assisted BN Scaffold Fabrication Towards Highly Thermal Conductive Epoxy Composites.
ACS Applied Materials and Interfaces, 2020With the trend of device miniaturization and higher integration, polymer composites with high thermal conductivity are highly desirable for efficient removal of accumulated heat to maintain high performance of electronics.

Polymer-Plastics Technology and Engineering, 1978
Abstract : This report reviews the state of knowledge of the basic factors that control the durability of epoxies in service environments. The structure-property relations of amine (diethylene triamine, DETA)-cured bisphenol-A-diglycidyl ether (DGEBA) and amine (diaminodiphenyl sulfone, DDS)-cured tetraglycidyl 4,4'diaminodiphenyl methane (TGDDM ...

Epoxy Functionalized Hyberbranched Polymer/Epoxy Blends
1999Abstract : 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

The effect of brominated epoxy on epoxy/phenolic reactive blends [PDF]
Journal of Applied Polymer Science, 2018 ABSTRACTInnovative reactive blends containing epoxy and brominated epoxy (BE) incorporated with resole‐type phenolic were studied with the aim to elucidate the curing kinetics and the final thermomechanical characteristics of this unique system. Curing kinetics was investigated by means of the activation energy determined using differential scanning ...

Publisher Summary Epoxy resins are formed from an oligomer containing at least two epoxide groups and a curing agent, usually either an amine compound or a diacid compound. Epichlorohydrin is the monomer used for the synthesis of glycidyl ethers and glycidyl esters.

Toughening of aromatic epoxy via aliphatic epoxy copolymers
Polymer, 2014Abstract While aromatic diglycidyl ether of bisphenol A (DGEBA) based epoxy polymer matrix systems are important for high-performance applications, their brittle nature is an issue that needs to be addressed. In this paper the authors show that small additions of a more flexible aliphatic epoxy copolymers, both di- and tri-functional, can ...

Determination of Epoxy Resin Concentration in Epoxy Modified Bitumens
2021Recently open graded mixes using epoxy modified bitumen have begun to be used in New Zealand for general road surfacing applications. To reduce cost and potential risk to plant and machinery, commercially available epoxy bitumen is commonly diluted with standard grade bitumen.
