POLYMER PIEZOELECTRIC MATERIAL Russian patent published in 1995 - IPC

FIELD: polymer piezoelectric materials. SUBSTANCE: proposed material contains (mass parts): ceramic powder of lead titanate which contains additive of 0.01-5 mass % manganese oxide 400-1200, organic polymer matrix 100, plasticizer 10-30 and cross-linking agent 2.5-16. Polybutadiene chloride, polyvinylchloride or their mixture are used as mentioned above organic polymer matrix. Mixture of zinc oxide, magnesium oxide and stearic acid at ratio 1: 1: 0.5-7: 7.2-2.5-16 is used as mentioned above cross-linking agent. Thus prepared material has high elasticity and may be processed by extrusion. EFFECT: improves quality of the material. 4 cl, 2 tbl
