我们以一种独特的方式结合了两种现代超薄膜技术来生产异质结构薄膜。这些是等离子体沉积(这使得人们能够在任何具有活性的、在我们的情况下是带电的表面上获得薄的20-500-A明确的层)和聚阳离子/聚阴离子自组装的逐层沉积。后一种技术是我们小组最近发展起来的，它是基于相反电荷之间的静电吸引。阴离子和阳离子聚电解质从其水溶液中交替吸收到带电衬底上导致多层组装的形成
We combine in a unique approach two modern ultrathin film techniques for production of heterostructure films. These are plasma deposition (which permitted one to obtain thin 20-500-A well-defined layers on any solid surface with an active, in our case charged, surface) and layer-by-layer deposition of the polycation/polyanion self-assembly. The latter technique was recently developed in our group and is based on the electrostatic attraction between opposite charges. Alternating absorption of anionic and cationic polyelectrolytes from their aqueous solution onto charged substrate leads to the formation of multilayer assemblies
