FIGURE 15.23 The dependence of parameter b m on nanoclusters butt-end and cylindrical
surfaces are ratio S b / S c value for PC [55].

The stated above results were experimentally confirmed by the EPR-
spectroscopy method [56]. The Eqs. (4.63), (15.1) and (15.6) comparison
shows, that dipole-dipole interaction energy ∆ H dd has structural origin,
namely [56]:

As estimations according to the Eq. (15.30) showed, within the tempera-
ture range of T = 293÷413K for PC ∆ H dd increasing from 0.118 up to 0.328
Ersteds was observed.
Let us consider dipole-dipole interaction energy ∆ H dd intercommunica-
tion with nanoclusters geometry. I n Fig. 15.24 t he dependence of ∆ H dd on
the ratio S c / S b for PC is adduced. As one can see, the linear growth ∆ H dd at
ratio S c / S b increasing is observed, that is, either at S c enhancement or at S b
reduction. Such character of the adduced in Fig. 15.24 dependence indi-
cates unequivocally, that the contact nanoclusters-loosely packed matrix is
realized on nanocluster cylindrical surface. Such effect was to be expected,
since emerging from the butt-end surface statistically distributed polymer
