FIELD: chemistry.
SUBSTANCE: invention relates to the field of production of elastomeric materials based on polysiloxane compositions and can be used in high-technology fields of electrical engineering and robotics as an electrically active material in creation of sensors, actuators, artificial muscles. Proposed is a polysiloxane composition including polydiorganosiloxane with terminal hydroxyl groups and/or analogue thereof with terminal 3-aminopropyl diethoxysilyl groups by the formula (I), wherein X represents a hydrogen atom, -Si(OC2H5)2(CH3)2NH2; R1 represents CH3, C2H5or C6H5-; R2 represents CH3-CH2=CH - or C2H5-; one or multiple functional metallo-siloxanes by the formula (II), wherein M is a bi-, tri-, or tetravalent metal selected from Zn, Zr, Ti, and Fe(III); p+m corresponds to the valency of the metal, provided that p≠m, wherein m equals 1, 2, 3, or 4; R and Alk independently represent C1-C4–alkyls; R’ represents C6H5-, CH2=CH-, SH(CH2)3-, CH2=CHC(O)O(CH2)3-, CH2=C(CH3)C(O)O(CH2)3-, (III) or (IV); and ethoxysiloxane, wherein the mass ratio of polydiorganosiloxane(s) and the functional metallo-siloxane(s) is in the range from 3:0.1 to 3:2, and of the polydiorganosiloxane(s) and ethoxysiloxane is in the range from 3:1 to 3:4 pts. wt., respectively. Also proposed are a method for producing an elastomeric material, an elastomeric material produced by the claimed method, application thereof, and a method for adjusting the dielectric properties of the elastomeric material.
EFFECT: production of new elastomeric materials based on polydiorganosiloxanes with an adjustable value of dielectric permeability in the range from 3 to 100 (10 Hz) by a method ensuring production of a material containing no microdefects in the form of bubbles of residual amounts of a solvent, suitable for use in various electromechanical apparatuses.
