Effect of Water Content on the Piezoelectric Properties of Nylon 11 and Nylon 7

Abstract

Studies of the piezoelectric properties of odd numbered nylons such as Nylon 11 and Nylon 7 are important, not only in their own right, but because they provide a way to examine the generality of concepts put forward to explain the piezoelectric and pyroelectric properties of poly(vinylidene fluoride) films. Over the past several years, a series of studies of Nylon 11 and Nylon 7 have been carried out. In a recent study appropriate sample preparation and poling techniques were described, which gave rise to mechanically unoriented but polarized films of Nylon 11 with values of the piezoelectric strain coefficient, d31, as high as 7.1 pc/n.
