Alignment of Ag nanoparticles with graft copolymer bearing thiocarbonyl moieties

Facile networked alignment of AgNPs was attained by employing a graft copolymer bearing C=S moieties prepared via combination of free radical polymerization and polyaddition. The self-assembly induced the formation of the networked structure with cavities leading to translucency. The vertical conductivity depended on contact force, and suggests potential applications for printable devices such as touch screens.
