PIEZOELECTRIC BEHAVIOUR OF THE BLENDED SYSTEMS (NYLON 6/NYLON 11)

摘要

There is great importance for the study of combination of an engineering plastic polyamide and the best commodity product Nylon-6, which could lead to new blends with better piezoelectric properties. Keeping commercial approach in view Nylon 6 and Nylon 11 blends have been prepared. Compositions of two different proportions 90 :10 and 10:90 were developed. The blended samples were poled using Corona discharge technique with poling field of 200 kV/cm and 350 kV/cm. The piezoelectric coefficients (d_(33)), as a function of temperature for blended samples were measured up to 100°C with Piezometer. The study suggests that due to mixing of small quantity of Nylon 11 in the Nylon 6 (10:90) the piezoelectric response has improved considerably despite of the fact that Nylon 6 is not a piezoelectric material. The study indicates that even blending of small quantity (10%) of Nylon 11 in the (90%) Nylon 6 generates good piezoelectric response. The measured piezoelectric response of such compositions is almost equal to the pure Nylon 11.
