Bilayer polymer films which contain microstructured conducting layer of radical ion salt
of TTF-I or BEDT-TTF-I on the surface of different polymers were obtained. Sensitivity of conducting layer to water vapors mostly depends on the polymer nature. Conductivity of films based
on cellulose triacetate and poly(carbonate-siloxane) copolymer remains constant while the films
are exposed to water vapors. These films are recommended as suitable for tactile devices which
are able to operate in biological environment. Conductivity of polycarbonate bilayer films changes
reversible under water vapors treatment. These films may be use dinnovelsensor devices.

The solid forms of an aluminium-silicate flocculate-coagulant were received by the drying. It
is established that the final product of a solids process is sulfate of aluminum and insoluble dioxide of
silicon. Was studied efficiency of purification of modeling sewage from the weighed substances and
iron in comparison with aluminum sulfate. It is proved that process of drying leads to loss of flocculate
properties of solution of an aluminium-silicate flocculate-coagulant.
