摘要：

Thin films of nylon 79 were prepared by vapor deposition polymerization of 1,7-diaminoheptane and azelaic acid chloride. Preliminary values for the piezoelectric stress constant, e31 (= 2 mC/m2), and the pyroelectric constant, p3 (= 2 mC/m2 K), were obtained for poled films. Three relaxation processes in the temperature dependence of the dielectric constant Ε3 were observed at -130°C (γ), -50°C (β), and 70°C (α) similar to those for nylon 7 and 11 and aliphatic polyureas. The piezoelectric constant e31 remained up to about 130°C.
