Polymer formulations containing urethane acrylates, adhesion promoters and conductive monomers. By selecting suitable conductive monomers, it is possible to obtain formulations having a volume resistivity of 10 6 to 10 10 Ohm·cm after acclimation at 25° C. and 50% relative humidity for one week. Such formulations are suitable for incorporation into electro-optic materials, such as electro-optic displays or variable transmission films, eg for architectural applications. In other embodiments, the formulation additionally comprises metal oxide nanoparticles to alter the refractive index and/or electrical conductivity. The addition of certain metal nanoparticles additionally facilitates non-destructive measurement of layer thickness using X-ray fluorescence spectroscopy. |
