METHOD OF PRODUCING POLYMER-INORGANIC SENSORS FOR POLAR SUBSTANCES Russian patent published in 2008 - IPC G01N33/00 B32B27/06 

FIELD: chemistry; express analyses.

SUBSTANCE: in the known method of producing polymer-inorganic sensors for polar substances by action on amorphous-crystalline polymer, the polymer is used in the form of a non-oriented or partially oriented film (Film) from 10 to 300 mcm thick, the action including stretching of the Film at a rate of 1 to 200%/min to a deformation degree of 50 to 400% performed in liquid alcoxysiloxane or liquid alcoxysilane, followed by further steps of treatment of the stretched Film for at least 1 hour with vapour of water solution of an acid, ammonia or amine at a concentration of 5% or higher, the Film washing and drying in isometric conditions. The sensors produced are stable during storage and can be used repeatedly.

EFFECT: known method of producing polymer-inorganic sensors for polar substances is simplified, its labour-intensity and energy-intensity are reduced.
