Effect of Chain Flexibility of Epoxy Encapsulants on the Performance and Reliability of Light-Emitting Diodes
In this work, cycloaliphatic epoxy resin (3-4-epoxycyclohexane) methyl 3-4-epoxycyclohexyl-carboxylate (ECC) was formulated with flexible hydrogenated bisphenol A diglycidyl ether (HBADGE) to investigate the effect of chain flexibility on the performance and reliability of epoxy packaged Light-emitting Diode (LED) devices. The properties of epoxy packaging materials were characterized by using d...

Effect of silicone resin modification on the performance of epoxy materials for LED encapsulation
Cycloaliphatic epoxy resin was modified by phenyl methyl silicone resin to investigate the influence of silicone content on the performance and reliability of epoxy packaged light-emitting diode (LED). The silicone modification of epoxy encapsulants was characterized by transform infrared (FT-IR) spectrophotometer. Differential scanning calorimetry (DSC), thermogravimetric analyses (TGA), dynami...

One-Pack Epoxy Foaming with CO2 as Latent Blowing Agent
In this work, we have successfully developed a novel approach to epoxy foaming using CO2 as the latent blowing agent. The active amine groups of a commercially available curing agent for epoxy resin are blocked by CO2 to obtain ammonium carbamate. The prepared ammonium carbamate can be decomposed by heating. Above 100 °C, CO2 is released from the amine groups and acts as the blowing agent, whil...

[Composites Part A]Nanopolydopamine Coupled Fluorescent Nanozinc Oxide Reinforced Epoxy Nanocomposites
Fluorescent epoxy nanocomposites reinforced with polydopamine (PDA) functionalized zinc oxide (ZnO) nanoparticles have been obtained. Results reveal that the PDA functionalized ZnO nanoparticles are dispersed uniformly in the epoxy nanocomposites. The enhanced tensile strength of the epoxy nanocomposites filled with PDA functionalized ZnO nanoparticles (up to 106.7 MPa) is ob...

Effect of epoxy resin on the thermal behaviors and viscoelastic properties of poly(phenylene sulfide)
In this work, thermal behaviors and viscoelasticity of the PPS/epoxy resin mixtures prepared by melt mixing were studied, and the rheology was used as a tool to further explore the relation between chain structures and properties of the mixtures. The results show that the epoxy resin can promotes degradation and branching of the PPS during melt mixing due to its poor thermal stability. The formati...

28. Plant Oil-Derived Epoxy Polymers toward Sustainable Biobased Thermosets
Epoxy polymers (EPs) derived from soybean oil with varied chemical structures were synthesized. These polymers were then cured with anhydrides to yield soybean oil derived epoxy thermosets. The curing kinetic, thermal and mechanical properties were well characterized. Due to the high epoxide functionality per epoxy polymer chain, these thermosets exhibited tensile strength over an order of ...

Toughening of Epoxy Resin System Using a Novel Dendritic Polysiloxane
Dendritic polymers have attracted increasing attention in the field of epoxy resin toughening. This paper is the first report of the use of a novel dendritic polysiloxane (DPSO) bearing high epoxide groups to modify the diglycidyl ether of bisphenol-A (DGEBA). The thermal properties, toughness and morphology of the cured epoxy resins were examined by DSC, TGA, impact testing and SEM. The chemica...

Studies on the Thermal Properties of Epoxy Resins Modified with Two Kinds of Silanes
Dimethyldiethoxysilane (DMDES) and diphenyldimethoxysilane (DPDMS)-containing epoxy resins were synthesized by dehydration polycondensation. The chemical structures were determined by FT-IR, 1H NMR, and 13C NMR. The cured samples, with 4, 4''''-diaminodiphenylmethane (DDM) as curing agent, were investigated by differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), thermograv...

Mechanical and thermal properties and morphology of epoxy resins modified by a silicon compound
A silicon compound (GAPSO) was synthesized to modify the diglycidyl ether of bisphenol-A (DGEBA). The chemical structure of GAPSO was confirmed using FT-IR, 29Si NMR and GPC. The mechanical and thermal properties and morphologies of the cured epoxy resins were investigated by impact testing, tensile testing, differential scanning calorimetry and environmental scanning electron microscopy. The impa...
