Abstract (en)
[origin: WO8503596A1] It is discovered that a liquid dispersion of polymer powder particles, predominantly of polyvinylidene fluoride, simultaneously: (a) can suspend electrical property additives, such as crystalline, hard, dense particles of generally spherical shape, uniformly in desired concentrations; (b) while containing a useful concentration of any of a wide range of such particles, can be deposited by high shear transfer to a substrate in accurately controllable thickness and contour; (c) when so deposited can be fused into a continuous uniform film which has low absorptivity, e.g., of moisture, and acts as a barrier film; (d) where desired, can, as one layer, be fused with other such layers, containing other electrical property additives, to form a monolithic electrical component; and, (e) in general, can meet all requirements for the making of any useful electrical circuit components, including electroluminescent lamps, by printing and coating techniques with a high degree of accuracy and controllability.
