High thermal conductivity of bulk epoxy resin by bottom-up parallel-linking and strain: a molecular dynamics study [PDF]
arXiv, 2018 The ultra-low thermal conductivity (~0.3 Wm-1K-1) of amorphous epoxy resins significantly limits their applications in electronics. Conventional top-down methods e.g. electrospinning usually result in aligned structure for linear polymers thus satisfactory enhancement on thermal conductivity, but they are deficient for epoxy resin polymerized by ...

Efficient Hole Injection From Indium Tin Oxide in Quantum‐Dot Light‐Emitting Diodes
Advanced Functional Materials, EarlyView.The realization of QLEDs‐based displays remains challenging due to the acidic surface from PEDOT:PSS. Here, an analysis is conducted by examining the degradation mechanism of PEDOT:PSS. By replacing PEDOT:PSS with 2BrCzPA, the formation of strong dipoles at the ITO/2BrCzPA SAM interfaces exhibits excellent hole injection abilities.

Curing and post-curing luminescence in an epoxy resin [PDF]
arXiv, 2006 A spontaneous luminescence is reported when epoxy resin samples are heated in air. This phenomenon is very sensitive to the nature of the atmosphere. The same treatment in nitrogen leads to an extinction of the luminescence. The emission process is restored when samples are kept for a sufficient time in air.

Postbuckling behavior of graphite-epoxy panels [PDF]
, 1984 Structurally efficient fuselage panels are often designed to allow buckling to occur at applied loads below ultimate. Interest in applying graphite-epoxy materials to fuselage primary structure led to several studies of the post-buckling behavior of ...

Glass transition of an epoxy resin induced by temperature, pressure and chemical conversion: a configurational entropy rationale [PDF]
, 2001 A comparative study is reported on the dynamics of a glass-forming epoxy resin when the glass transition is approached through different paths: cooling, compression, and polymerization. In particular, the influence of temperature, pressure and chemical conversion on the dynamics has been investigated by dielectric spectroscopy.

Advanced Functional Materials, EarlyView.Internally catalyzed siloxane dynamic chemistry is demonstrated resulting from amides covalently linked through alkyl chains to siloxanes. The alkyl length in the siloxane‐containing monomer tunes the network cross‐link density. Siloxane exchange dynamics are faster with increasing cross‐link density, because associative exchange is second order in ...

The effect of clay on the mechanical properties of epoxy resins subjected to hygrothermal ageing [PDF]
arXiv, 2016 Epoxy polymers are an important class of material for use in various applications. Due to their hydrophilic nature, epoxy resins tend to absorb moisture. Absorption of moisture degrades the functional, structural and mechanical properties. For polymers, it is known that moisture absorption can lead to both reversible and irreversible changes.
