Abstract

Abstract A substrate structure having three-dimensional functional film network comprising a plurality of radio frequency discharge plasma film layers. The plasma film layers include a first layer, comprising a plurality of a first functional group, and a second layer, comprising a plurality of a second functional group. The employment of three-imensional film networks with desired functional groups located either on the periphery or both the periphery and interstitial spaces of the networks provides means for significantly increasing the surface functional density.
