“…So, the presence of EG particles, at a relative smaller content, reduces the dipole-dipole interactions of PUPH molecules and, plays an inert diluent role to decrease the self-association interaction of PUPH molecules. Similar tendency has been observed in other composites [16,17,18,19,20].However, for high content (15-30 wt%) of EG particles, an increase in the T g is observed. This can be associated with the reduction of molecular mobility of the polyurethane chains imposed by the EG particles.…”

Segmented polycarbonatediol polyurethane has been synthesized and modified with different amounts of graphite conductive filler (from 0 to 50 wt %). Thermal and Dynamical thermal analysis behavior of the composites clearly indicates the changes in polyurethane relaxations upon addition of graphite. Broadband Dielectric Spectroscopy has been used to study the dielectric properties of the composites in the frequency range from 10 −2 to 10 7 Hz and temperature window of -140 to 170 • C. Conductivity, relaxation processes associated with different molecular motions, Maxwell-Wagner-Sillars and electrode polarization are discussed and related with the graphite content.

“…The relaxation time was mainly measured using dielectric spectroscopy [183,184], NMR spectroscopy [185][186][187][188][189][190][191][192], and neutron scattering [193,194]. T g was determined using dynamic mechanical spectroscopy [195][196][197][198][199], calorimetry [191,[200][201][202], and dilatometry [184,203] techniques. Since the mobility of the polymer chains around the fillers is related to the interfacial interaction, the presence of the interaction and their strength can be estimated by measuring T g and relaxation time [11,204].…”

Composite materials and especially polymer composites are widely used in daily life and different industries due to their vastly different properties and design flexibility. It is known that the properties of the composites are strongly related to the properties of its constituents. However, it has been reported in many studies, experimentally and by simulations, that the characteristics of the composites do not follow the rule of mixing. It means that in addition to properties of the constituents, there are other parameters affecting the final physicochemical properties of composites. The interfacial interactions between fillers and host is one of the factors which can strongly affect the properties of the composite. In this review, we summarized the type of interactions between the constituents, their improvement techniques, interaction measurement methods, and the effects of interfacial interactions on thermal, mechanical, and electrical properties of composites.

“…Dynamic mechanical testing is a common technique to study the effect of particles on the T g of polymers, [11][12][13][14][15][16][17][18][19][20][21][22][23] and a summary of these studies is given in Table I. Many investigators draw conclusions based on the temperature of the maximum in the isochronal loss tangent, tanδ = G"/G' (abbreviations are defined in the appendix).…”

We review the literature concerned with the effect of proximity to a filler surface on the local segmental mobility of polymer chains. This mobility is commonly assessed from either the glass transition temperature, Tg, or the segmental relaxation times measured by mechanical, dielectric, or NMR spectroscopy. Published studies report increases, decreases, or no change in Tg upon the addition of carbon black, silica, and other reinforcing fillers. Similarly, the segmental relaxation times have been found to increase or be invariant to the presence of nanometer-sized particles. Some of these discrepancies can be ascribed to ambiguous methods of data analysis; others likely reflect the variation in filler-polymer interaction among different systems. There are unequivocal examples of polymers that have segmental dynamics and glass transitions unaffected by nano-particle reinforcement. However, the general principles governing the behavior remain to be clarified, with further work, focusing on the micromechanics at the particle interface, required for resolution of this important aspect of rubber science and technology.
