A layer-by-layer technique was used for deposition of nano-layers of polyelectrolytes onto nonwoven textiles.

Polypropylene and polyester nonwovens grafted by acrylic acid were used as starting material for deposition of polymer complex layers. It was found that a layer-by-layer technique makes it possible to produce materials with diversified properties. Depending on the layer structure, hydrophilic properties, electro-kinetic potential and absorption of dyes were changed. Water-tightness and remission of methylene blue were measured for samples with different types of deposited layers.Using deposited layers as nano-reactors polymerization of aniline was carried out in order to obtain electro conducting materials. Moreover, nano-particles of gold, silver and metallic oxides were deposited onto such layers. Properties of the obtained materials were tested. It was found that particles are distributed without aggregation.
