Electrostriction Effect of Polymers Exhibiting Dielectric Relaxation

Electrostriction Effect of Polymers Exhibiting Dielectric Relaxation [Pg.33]

In this section we consider electrostriction in a polymer exhibiting dielectric relaxation. We assume for simplicity a single relaxation process  [Pg.33]

In the right-hand side of Eq. (106), the first term is frequency-independent, the second term and the last term have a frequency dependence similar to that of (s — sj) and s , respectively. The last term has a maximum or a minimum at X = 1, depending on the sign of as. On the other hand, the first term on the right-hand side of Eq. (107) has a maximum or a minimum at X= 1, depending on the sign erf 8As/8S, in a similar way to [Pg.33]

The second term on the right-hand side of Eq. (107) has the form indicated in Fig. 15. The curve goes through 0 at X = 1 and has the form of a derivative of e with respect to X. [Pg.34]

If we measure the frequency dependence of k and k over a wide frequency range, we can obtain values erf dzJdS, SAz/dS and i.e., the strain dependence of characteristic parameters of relaxation. [Pg.34]
