Unsaturated Polyester Resins: Chemistry and Technology

“…An increase in dynamic fracture toughness was observed. The importance of the interface strength between the UPR matrix and inorganic polysilicic acid nanoparticles was ascertained using the nanoparticles modified by the reaction of silanol groups on the nanoparticles surface with phenyltrimethoxysilane, 2-(p-styryl)ethyltrimethoxysilane and 3-(trimethoxysilyl)propyl methacrylate [223]. The homogeneous product cured at 150 • C was a transparent inorganic/organic hybrid material, which exhibited reduced shrinkage on curing and enhanced dynamic mechanical properties, due to increased interfacial force between the inorganic and organic components.…”

Nanodot‐Enhanced High‐Efficiency Pure‐White Organic Light‐Emitting Diodes with Mixed‐Host Structures

“…1). [21] The white emissive layer was made up of a mixed-host of 50 wt % 2-(N,N-diphenyl-amino)-6-[4-(N,N-diphenylamino)styryl] naphthalene (DPASN) and a 50 wt % N,N′-bis-(1-naphthyl)-N,N′-diphenyl-1,10-biphenyl-4-4′-diamine (NPB), doped with 0.5 wt % yellow-lightemitting 5,6,11,12-tetra-phenylnaphthacene (Rubrene). The (t-NPD) was studied for comparison.…”
