METHOD OF PRODUCING POLYANILINE COMPOSITE [PANI(NX)-TiO)] Russian patent published in 2011 - IPC C08L77/00 B82B3/00 

FIELD: chemistry.

SUBSTANCE: invention relates to production of a conducting film based on a hybrid polymer-inorganic composite of polyaniline filled with titanium oxide nanoparticles [PANI(NX)-TiO₂)]. The polyaniline composite [PANI(NX)-TiO₂)] is obtained as follows. A polyaniline solution (basic) solution in an organic solvent is mixed with titanium dioxide precursor gel in 2-methoxyethanol and a dopant solution in 2-methoxyethanol, dimethyl formamide, dimethyl acetamide, formamide or N-methyl pyrrolidone. Components are mixed in volume ratios corresponding to content of titanium dioxide in the composite in amount of 5-70% of the weight of PANI. In order to obtain a composite film based on the [PANI(NX)-TiO₂)] composite, the composite is prepared in form of a film [PANI(NX)-TiO₂)] through spin-deposition of the polyamine solution and titanium dioxide gel in 2-methoxyethanol onto the substrate or through immersion followed by drying on air.

EFFECT: invention enables to obtain a composite conducting film with controlled thickness and uniform distribution of titanium dioxide particles in the polymer matrix.
